New intake manifold likely

**Boosted2.0** · 06-26-2007, 10:11 AM

Just a heads up - it is looking VERY likely that I will be developing a new 2ZZ-GE intake manifold in conjunction with Littlerocket as a result of the research we have been doing on 2ZZ-GE head flow. It will move the peak torque to a higher RPM (probably around 8000) and should represent a significant increase in flow and HP.

It will not clear the stock hood (although it won't stick out too far). The Throttle body we use will likely NOT be a toyota peice so a standalone like the Power FC or Hydra will be required.

Best gains will require head porting and some other modifications to increase the rev range to a 9000 RPM redline, but our initial testing idicates it should create significant gains even on a stock GTS.

Before anyone asks:

No - we don't have an exact timeline
No - it will probably not incorporate ITBs
The high power version will probably not be designed to clear the hood - plan on cutting a hole to clear it
We will TRY to design a version that clears the stock hood and still makes good power but we promise nothing at this point
Yes - we will be doing dyno testing before the product is offered
Yes - it will continue to utilize the MAF

Its waaaay to early to say what the pricing will be with any certainty, but I would guesstimate it in the $700 - $1000 ballpark.

Littleguy · 06-26-2007, 10:19 AM

I'm guessing if it won't clear the celica hood, there will be no way it fits the MRS? Cutting the firewall maybe?

great nothing for the 1zz huh

of course not. I wouldn't R&D anything for it either. the head design is cr@p.

vegeta4ss · 06-26-2007, 10:53 AM

I like the idea of a nicer manifold, but the whole hood cutting thing is a big deterrent(for me at least). Good job boosted, I figured if this would ever get done that you would have your hands in it somewhere.

GTsRasta · 06-26-2007, 11:11 AM

The TRD hood with the bulge would be the way to go then. Problem solved.

**jlitman** · 06-26-2007, 11:16 AM

Boosted,
Think there'd be any value in porting the Greddy S/C intake manifold? If so, I may just sent that to you when everything is in pieces.

Good idea. The invader maybe too?

GTsRasta · 06-26-2007, 11:30 AM

Nah, I think the invader hood only has a bulge in that small part it's lifted up in, which would be closer to the radiator. Otherwise, it looks like the space where it's over the intake manifold is flat like stock.

Oh, and he did say that porting the restrictive 3rd runner and giving it thermal coatings would help performance a bit in a pm reply. Give it a try!

Yup - it should work perfectly assuming the dimensions fall where we think they will.

Yes - the Greddy manifold would definitely benefit from some porting - look at the number 3 runner when you take it off - its got a huge boss for the bolt passage restricting it. Theres also a bunch of casting flaws that could be improved. There is also a friction reducing coating used for the inside of intake runners that could be applied. It might also be worthwhile to port match it to the head. For that matter porting the head would probably be worth your while as well if you have the budget for it.

Yeah I don't think the invader would clear it.

Will it clear an XRS hood?? I know the XRS has more room in that area i believe.

JSPITZ · 06-26-2007, 01:37 PM

Yeah way more, went to put collant in my corolla last week and was like dam I could put a big block v8 in here j/k but it does have a lot of room

GTsRasta · 06-26-2007, 01:38 PM

I saw a 1zz Corolla with the TRD supercharger in the engine bay, so my first guess is yes. The special hood made for the Celica was meant to house the same 1zz TRD supercharger. So you could be good to go. Measure your clearance to the hood to be sure when the time comes.

metal112524 · 06-26-2007, 01:40 PM

why not design it around the trd hood as to allow for a viable alternative to cutting the stock hood.

Boosted doesn't care about it clearing the celica hood. I'd be willing to bet it will fit into an Elise just fine.

GTsRasta · 06-26-2007, 02:40 PM

I'm sure he'll see what he can do. Limiting a product to a particular group of buyers wouldn't be a good thing.

Redliner9k · 06-26-2007, 02:51 PM

Hmm, am interested to see what your testing has brought up. I tried to design a IM a while back for the 2zz-ge, but endless simulations came to the conclusion that the gains were small and not worth my time. Maybe you guys found something I didn't.

I think you'll see that these will be sold to elise owners much more than celica owners, as the elise people are more willing/able to spend the kind of money on a product like this. We (2zz Spyder/2zz Celica people) should be happy the elise uses a 2zz or we wouldn't see alot of the new products being developed right now.

Celicasaur · 06-26-2007, 03:33 PM

ouch, 9000rpm peak? Isn't this then something for the real big guns only then with fully built blocks? I wouldn't mind cutting my hood for a good mod if it works, but that does sound a bit much for me personally.

Yeah this looks like one for the race crowd and moslty elise heads.

No idea if it will fit the elise without modification or not. The lack of hood clearance is dictated by flow and intake pulse tuning, not packaging for a specific vehicle

Toyota already makes a nice manifold that clears the hood - it comes on the car stock.

The torque peak will be about 8000 not 9000 but we predict great power increases from 8000 - 9000

Built and ported motors will see more benefot, but it should pick up some decent power on a stock motor too. The power is all ricer math right now anyways. We've got the flow issues figured out and the length ballpark dialed in but it needs testing and development. I just wanted to kind of throw a teaser out there so that the guys that DO want to maximize NA or turbo powered cars would be able to strat thinking about what they want to do with their hoods.

You should probably read what I posted. I said most. If you are willing to put the cash into you celica, than the hood should be no problem. And please learn to use the ' button on your computer.

metal112524 · 06-26-2007, 10:39 PM

I never asked for a manifold that clears the stock hood, said one that would utilize the trd hood at best.

youngxlos · 06-27-2007, 12:00 AM

if this requires the hood to be cut, then that means this is probably for a track car. besides if the peak power is at 8 to 9k then the low end would suffer and it would suck for a daily driver. good luck boosted.

Northy · 06-27-2007, 03:44 AM

will be keeping a close eye on this one for sure.

The AIT hood doesn't look that bad man:

You already invested a lot into your NA build, whats a little bit more?

**Boosted2.0** · 06-27-2007, 11:27 AM

To clarify - the goal here is to build a manifold for optimum power. The project is based on performance, not fit. When we find what works best thats what we will build. Form follows function - if this makes 10 or 15 HP then someone will make a hood or FRP cowl to clear it.

FWIW I have nothing against developing things for the 1ZZ, I just don't have the time right now and I would need manifolds, heads, etc. From what I've seen theres not enough money spent on 1ZZ performance to merit the time and investement it would require at this time, especially since we will be investigating a 2AZ swap kit.

I stand corrected! I figured the thick wallets of Lotus owners would prompt you to put the celica fitment a little lower on the totum pole. I'm glad to hear that you are strictly following a "form follows function" approach.

Its good to be back. I didn't see that thread, but I thought everyone knew I had a baby due and was going to be taking a while off to take care of mom and daughters /shrug

Anyways yes, we know exactly what the CFM difference will be.

The other night we were testing the effects of blending / porting the mating flange on the stock intake and I was screwing around with different things while Littlerocket blended the outlet. We already knew we wanted to change the runner length, but I was very suprprised to find after taking all the relevant measurements that we would have to use shorter runners than I originally thought to get to the total length we wanted. So I made a couple down and dirty runners to play with flow and stumbled on a design that flows at zero loss versus a radiused bell on the port. (The stock manifold causes quite a bit of flow loss versus just the port with a bell on it)

Shizuma · 06-27-2007, 01:13 PM

congrats on the baby...I assume everything went ok?

....nice...so you're going to keep the numbers and pictures proprietory until launch??...you tease

anyway, what about the plenum? Are you staying with a similar volume and design (eg integrated velocity stacks)...I can only assume that you'd want to keep the volume the same if not increase it due to the shift in the powerband...and what throttle body were you thinking about (brand? mm?....)....also, I've been wondering about the vaccuum nipples on the stock manifold and how they affect flow into the manifold itself, as they're located almost directly above the intake path of the incoming air...do you have any data on that specific point?

westrock · 06-27-2007, 01:14 PM

Shizuma · 06-27-2007, 01:20 PM

^ true, but you CAN roughly calculate what runner lengths will correspond to what RPMs (in terms of resonance frequencies), and from there you can make your adjustments...the fact that he said cutting the hood would be necessary makes me think that he's already taken straight runners (and therefore resonance frequencies) into account...he's also said that he's not done with the final design as well.....plus, I don't think Boosted is going to half-a$$ it

Yup - everything went great thanks.

Plenum may be a bit larger

Yes I am going to keep numbers and things under wraps until we have confirmed dyno proven results. I will say that the difference on a ported head is about 10% flow increase over the stock manifold configuration at 28" of vacuum

Throttle body will probably be custom. We are looking at a couple mustang throttle bodies and another custom manufacturer as well. We want to try about 80-85mm

The vacuum nipples being blocked or unblocked made no difference in flow on the stock manifold.

Shizuma · 06-27-2007, 02:00 PM

interesting...so you WERE testing on a ported head?...what kind of job was done on it? (3,5 angle...valve stems....etc)....also, the q45 TB I'm using on my manifold is 84mm at the neck...you can pick them up pretty cheap and the TPS can be wired directly into the harness (it uses the same voltage range)

When it comes to manifolds in a NA application the flow capabilities are only half of the equation. The major aspect of the design is the harmonics of the manifold. Your trying to develop a resonant "frequency" between the piston movement and the manifold that will boost effeciency at a certain RPM. Thats something that can't be duplicated on a flow bench.

Nope. But the formula to get to that length is simple if you know where you want your torque peak, and you know the wave speed of the low pressure wave when the intake valves open opens and the number of crank degrees after intake valve opening that you want the pressure wave to hit at. Which I do.

Considering that I know all that AND I know exactly how far it is from the intake valve to the head flange and exactly how far it is from the manifold flange to the bell in the stock intake - I would say that I have enough info

Mind you all that math just gets you into the ballpark. eventually you have to go to a dyno and play with fine tuning the lengths to get the exact curve you want.

BTW - your post is wrong on the intake manifold runner length by over 2 inches.

Correct. The formula to calculate the length seems dead on, seeing as how we ran the stock manifold length through it and it came out right about 7000 rpm which is where the stock torque peak is.

The special hood made for the Celica was meant to house the same 1zz TRD supercharger. So you could be good to go. Measure your clearance to the hood to be sure when the time comes. __________________ 03 Celica GT-S, 6 Speed Manual, Carbon Blue >=) Performance Mods: eBay Intake, TWM Short Shifter, Kumosport Shifter Base Bushings

Limiting a product to a particular group of buyers wouldn't be a good thing. __________________ 03 Celica GT-S, 6 Speed Manual, Carbon Blue >=) Performance Mods: eBay Intake, TWM Short Shifter, Kumosport Shifter Base Bushings

I tried to design a IM a while back for the 2zz-ge, but endless simulations came to the conclusion that the gains were small and not worth my time. Maybe you guys found something I didn't. __________________ "Live For Lift"

Isn't this then something for the real big guns only then with fully built blocks? I wouldn't mind cutting my hood for a good mod if it works, but that does sound a bit much for me personally. Yeah this looks like one for the race crowd and moslty elise heads. __________________ Need Denso 440cc injectors for your N/A beast? I'm your man.

Boosted2.0 Moderator Join Date: Oct 2003 Location: Houston, TX Posts: 13,058 iTrader: (14)	To clarify - the goal here is to build a manifold for optimum power. The project is based on performance, not fit. When we find what works best thats what we will build. Form follows function - if this makes 10 or 15 HP then someone will make a hood or FRP cowl to clear it. __________________ Now offering: 2ZZ Performance Intake Manifold \| 2ZZ Ported Headers \| 2ZZ Ported Cylinder Heads \| PowerFC Harnesses for DBW and Auto 2ZZ \| MR2 Spyder 2ZZ Swap Kits \| Engine Builds \| Turbo / Supercharger installation \| Tuning

Since you have a design in mind, I can only assume you have a rough idea of how much more it will flow... ...btw, nice to see you back on the boards, I don't know if you saw it but somebody actually started a thread on you being gone lol __________________ Measure twice, cut once, swear, measure again, cut, cuss, measure one more time, cut your fingers, bad, cut again, kick the air compressor, bandage foot, retire.

Shizuma Automotive Masochist Join Date: Mar 2005 Location: Lexington, SC Posts: 3,854 iTrader: (27)	congrats on the baby...I assume everything went ok? ....nice...so you're going to keep the numbers and pictures proprietory until launch??...you tease anyway, what about the plenum? Are you staying with a similar volume and design (eg integrated velocity stacks)...I can only assume that you'd want to keep the volume the same if not increase it due to the shift in the powerband...and what throttle body were you thinking about (brand? mm?....)....also, I've been wondering about the vaccuum nipples on the stock manifold and how they affect flow into the manifold itself, as they're located almost directly above the intake path of the incoming air...do you have any data on that specific point? __________________ Measure twice, cut once, swear, measure again, cut, cuss, measure one more time, cut your fingers, bad, cut again, kick the air compressor, bandage foot, retire.

Shizuma Automotive Masochist Join Date: Mar 2005 Location: Lexington, SC Posts: 3,854 iTrader: (27)	^ true, but you CAN roughly calculate what runner lengths will correspond to what RPMs (in terms of resonance frequencies), and from there you can make your adjustments...the fact that he said cutting the hood would be necessary makes me think that he's already taken straight runners (and therefore resonance frequencies) into account...he's also said that he's not done with the final design as well.....plus, I don't think Boosted is going to half-a$$ it __________________ Measure twice, cut once, swear, measure again, cut, cuss, measure one more time, cut your fingers, bad, cut again, kick the air compressor, bandage foot, retire.

Shizuma Automotive Masochist Join Date: Mar 2005 Location: Lexington, SC Posts: 3,854 iTrader: (27)	interesting...so you WERE testing on a ported head?...what kind of job was done on it? (3,5 angle...valve stems....etc)....also, the q45 TB I'm using on my manifold is 84mm at the neck...you can pick them up pretty cheap and the TPS can be wired directly into the harness (it uses the same voltage range) __________________ Measure twice, cut once, swear, measure again, cut, cuss, measure one more time, cut your fingers, bad, cut again, kick the air compressor, bandage foot, retire.
