Nitrous on a supercharged Celica

[MyRomeo]

its your choice at the end of the day but I know what I would be investing in

[Celicasaur]

No kidding on the price ^^^

My system cost me nearly

[MyRomeo]

mine didnt cost THAT much but was still close to if not slightly over 1000 USD, IMO worth every penny tho!

I'm planning on upping my jets to 50bhp in a few weeks time when I get a chance and hopefully the next purchase will be a progressive controller and some 75hp jets

[Celicasaur]

yeah i need the progressive controller too...ahem, that'll be another couple hundred more to spend...

[MyRomeo]

Indeed...

That will be my summer treat I think!

Got a NX (I think) controller knocking about somewhere but never tried it with the WON kit, it should work the same but ive never had the chance to set it up.

[AndrewsElise]

any more updates? I'm very curious how the car is running

[Gtsjeg04]

It was working just fine for a couple of weeks. While I was at the track trying to tune out the fuel, a V8 broke something a wet the whole track down. I shut the car off in the staging lanes and forgot to turn off all of power switches. I came back about 15 minutes later after they had the mess all cleaned up and tried to start the car and it was one loud pop. Blew the intake pipe right off the throttle body and bent the throttle plate into a "U". So the throttle is off being fixed while I am setting up a new fuel setup, and try to buy another motor so I go bigger on the boost and nitrous. I am not sure what happened while I was away from the car but I do know the next time I turn the car off all those switches will be off first. Nothing happen to the supercharger or the engine internals. Airfilter caught on fire. Nothing to special. Should be back at it buy this weekend. I think the nitrous fired when the car was off and pooled on the throttle plate and when I went to start the car it fired off the huge puddle of nitrous and that is what blew all the extra pieces off the TB. All in good fun.

[v3bahumut]

Nitrous doesn't pool, fuel does.

[Entranced]

I bet that was a fun sight to see for everyone around you in the staging lanes. haha. Did you manage to get a run down before it backfired?

[Gtsjeg04]

Not a good run. I have been messing with the launch control trying to get my 60ft times lower.

Probably just going to run a 35 shot.

[Celicasaur]

That looks delicious

[MyRomeo]

for many years that has been the car that I would buy first if I had the money... one day!!!

Get a progressive setup and take the nitrous slowely on it, remember, FI will make more power than NA on the same jets so 35hp could give you 50+ quite easily.

now excuse me whilst I mop up this drool...

[newman]

Yeah, let's hope it doesn't become a 70,000 dollar paperweight. :O

HAHA, thanks.

I'm going to start REALLY small. The problem w/ the lotus is that the only tuning options (that don't require hacking up the factory harness) is 2500+ which is a bit more more than I want to spend right now...

So essentially I have no timing control.

So I'm going to install a fast acting EGT probe and obviously a wideband and start with a 25 shot and work up from there. Definitely not going to go any bigger than a 50 shot. I do have a window switch.

I don't have a progressive controller, so I'll probably hold off on the juice til 4200 or so...

[the ronin]

That's gonna be such a pretty paperweight with no timing control....dude get the Gotham tune from Charlie before you waste your engine........4200, juice and when you hit lift at 4600 you're screwed.......oh well

[newman]

The more and more I'm reading the more and more it seems like some cluster****.

Ronin, what are your thoughts on a smaller pulley + methanol tune, ecu in open loop?

[Entranced]

I'll take your paperweight once you make it that

[newman]

Ronin I PMed you...

[MyRomeo]

if your willing to spend the time and money on a good nitrous setup can I advise you speak with the wizards of nos in the UK? their stuff has THE best reputation over here and I believe is just starting to get its foot in the US market.

I run a wizards kit as does celicasaur and i'm sure Ron will agree with me, they are superb.

Not sure how the exchange is at the moment but I think its in your favor at the moment?

www.noswizard.com

for interest its the streetblaster 150i wet kit that we both run but ron has gone direct port where I am single fogger.

They also have a superb help forum and the company owner frequents the forums daily and is very helpful.

I would have no doubt at all that set up right and using the best kit available you could get a substancial gain from your lotus

any pointers just ask, were all here to help

.There's safer ways to make power and of course smaller pulleys with a proper tune work..

[Gtsjeg04]

Doesnt that car come stock with a blower?

[Gtsjeg04]

Tested out the 100 shot direct port set up today. its quite intense and rather sporty.

I wouldn't use the nitrous either -- high cylinder pressures on stock pistons will get you cracked ring lands in no time. Yes nitrous will cool the charge, but it will greatly lean out the mixture causing in-cyilinder temps to skyrocket.

Now, a 35 shot is probably okay with the stock pulley, but not with that 2.6" one, which is gonna make between 12 and 14 psi!!

As for the Lotus guys, anyone pushing 300 whp on a stock 2ZZ is a cvnt hair away from having a bad day. You can easily break a piston with 0 knock and a great tune around that power level. Ask me how I know.

didn't need to read past this post.


but anyeway, 50 shot or go home. /thread.



seriously, you'd be surprised at what a 50shot would do on a boosted motor.

otherwise, dont bother. sell it and get some $$

ooweeee..uumm can you please post a vid. you got some balls of steel man.

Bah, that's an insult.

He's clearly got balls of forged magnesium

Thank you Thank you. I will try to see if I can get some today at the 1/8 mile track.

I just had some dyno time to trim some things out and I was putting 225 whp with ignition timing pulled a little to allow for the juice. She is moving pretty good

[Gtsjeg04]

Cut a 8.576 pass at the track today. Lost my call out race on a local forum to a K swaped 92 honda hatch. That guys **** was fast. He broke something after the last 2 out of 3 races. Any who, it seems to be holding the 100 shot of nitrous just fine on the boost. Tried a 150 shot but i couldnt keep it undercontrol. I dont see what the big deal is. Nitrous isnt as bad as everyone makes it out to be. Its far easier to setup than a turbo or supercharger setup.

[StraightXrs]

Would love to see what that would be on a 1/4 mile.

[Gtsjeg04]

there is still power to be had. It should be shaking down a solid 8 second pass here shortly. I am going to convince the old lady to let me take it to Montgomery AL to 1/4 mile track and see what happens.

[Entranced]

8.5 in the 1/8th is quick! That's gunning for a low 13 run.

[Gtsjeg04]

It could have ran better. The tune on the car still needs some working out.

[Gtsjeg04]

Here is the dyno with out nitrous.



Here is the nitrous setup that I am running now.











whats everyones thoughts

[Celicasaur]

Nice!!! Good to see a direct port set up on a 2zz y0!!!

Don't take this the wrong way, but are the nitrous and fuel lines both the same size? If they are, then you'd be better off with trimming the fuel line slightly to prevent any lean hits on activation. That NOS system distribution block is also very questionable and I reeeeally think you'd get significantly better and safer results with using a wizards on nos block (if that's possible to mate with NOS solenoids...i dont know). Those lines in general are pretty long and I'm going to have the same problem as you when I finally put mine all together. Hmm...

About that dyno...I might be reading it wrong, but that 224whp is just from the S/C, right? Man you must be soooo quick with the added boost of juice

[Gtsjeg04]

The lines are the same size around but not the same lenght. They are about 3inches shorter. The NOS block isnt questionable. It is equal distance and distributes as evenly as possible. I think you guys(Brittish) are just very partial to that brand which is totally cool just not for me. The longest the lines are is 18 inches which isnt very long compared to lines from a single wet kit. It is a very well thought out and planned kit. There wasnt a skipped step. The stainless lines were used bc i couldnt get a good bend off the nossles to get the hood to close right.

Yeah its 224.9 WHP just on the super charger, is that good? I am thinking about taking it to the dyno and maxing it out just to see and then roll the timing back to allow for the nitrous. I run more 112 leaded octane gas through this thing than regular gas now that my sponsor is picking up the gas tab. However the dyno was done with 93 octane pump gas.

[Entranced]

wtf, I want a gas sponsor! lol. and damn.. your engine looks busy! lol. 225whp isn't bad at all if your running with a bit of timing pulled.

Keep it up man!

[Gtsjeg04]

Its deffinently not a lazy engine. How many horses are you running in your celica? I wonder who has the most on a roots type supercharged celica.

[Celicasaur]

There's one guy in the uk with around 260hp ~ 240ish whp. And there's a couple others...I'm thinking of a Spectra blue coloured one, but I can't remember whom...

224whp is really good if you've taken away some timing also I commend you for being different and seeking power down this road...I'll be doing the same on my high compression N/A engine very soon. When you went to the 1/8 track the other night, did you do that on street tyres? which ones did you run for that? Any plans to go to the 1/4 mile track and set some scorching times?

Oh and going back slightly, I stand by what I said about the nitrous system being less than ideal...NOS use generic solenoids, despite their pretty packaging. That distribution block really doesn't distribute evenly and those pipe lengths....personally I'd chop the fuel ones slightly shorter even still as the nitrous flows faster than fuel, which may result in another backfire under the wrong conditions...just a heads up bro. You've got a lovely car and I like the fact that you're mixing nitrous with a 'charger...I just hope nitrous doesnt get the blame, should something nasty happen inside the block.

[Gtsjeg04]

I would like to see there list of mods and the type of dyno they used to get those readings. Trying to make it as gentle on the block as possible thats why the timing is pulled so much. It could be a little leaner on the fuel at the last 2000 rpms but it kinda keeps it safer. The tires I was using were Goodyear R1's. They are a medium soft compound. I only bought them bc they fit on the stock wheels but they work pretty good. They are DOT approved. I am trying to get a group of people together to go to the nearest 1/4 mile track and see what she shakes out.

I'm not defending NOS but I am saying i dont think you stuck either distribution block on a flow bench and tested them and a three inch difference is plenty. Dont want to bog the car out. This is a fastest race not a safest race. The nitrous wont get the blame. According to most people on this site my car shouldnt have made it this far. I just think most people are scared of Nitrous. Once you respect it, its a great power adder and its safe. I should be heading out to the track with a couple of new pieces that should lower my times a few tenths of a second.

[Celicasaur]

Fair play man, I hope you manage to break into the 12's with your set up. I really do.

There's not enough 7th gen's that have run 12's and we need to change that

[Gtsjeg04]

I dont think 12's would be to far of a reach.

[Celicasaur]

On street tyres?

[Gtsjeg04]

I guess you could call them street tires. They are DOT approved road course tires. Not drag radials. But i can do a 5500 rpm drop and they dont spin, just grab and go. Goodyear R1's

[MyRomeo]

I would echo what Ron has said about this distribution blocks but if your happy then thats your call.


What I would strongly advise tho is get rid of the 90 degree joins on the injectors, fuel and nitrous alike dont like sudden bends, you would get much smoother delivery if you were to get rid of them bends but I don't know how possible this is using the braided lines.




ps, if it were my car I like Ron would have went WON but again, im british

oooh sounds lovely. I hope I can do that on my GSD-3 F1 Goodyear rubber. I'm going also have the compound specially softened with some magical treatment so that should help also.

If you look at the distribution blocks, there isnt a difference. But you guys can say what you will. Have you tried bending tubing? Better yet have you tried bending tubing for direct port nitrous? Thats about as good of a bend as its going to get to get it to fit under the hood.

I think you need to google goodyear R-1 and see what kind of tire I am talking about. There is a very big difference between the two.

[Celicasaur]

Ahhh crap, yeah I see what you mean....maybe the toyo r888 on the front wheels might give me comparable grip...

[hombredelassrta]

nifty. thats not a bad number at all w/o the nitrous

[Gtsjeg04]

The Goodyear R1's are a little more stout than those. And the R1's are less expensive as well. They Toyo's look pretty though.

Well as soon as I can get an engine built I am going to run a smaller pulley and bigger shot and see what happens. Stay tuned it should get exciting around these parts.

[hombredelassrta]

what pulley now, the 3.1?
