Nitrous into the Intercooler...

[Oo DaRk StAr oO]

Me and David talked about this I would like to get some feedback... i'm planning on shooting a 50shot into my Intercooler, whacha all think?

[swift 21]

i think you are one crazy mofo that is going to fly!

[Oo DaRk StAr oO]

I cant wait to meet up with all you guys!

[zac83]

not that it would be any major loss in power, but i think the intercooler material would absorb the extra coldness in the nos shot, loosing maximum compression... probably wouldnt do much for you that way since the intercooler steals heat above its running temperature AND steals coolness below its running temperature. not to mention the plumbing beyond the intercooler could steal coolness when you could put it alot closer to the intake.

not tryin to rain on a parade, just wana throw a physics spin on it.

[Oo DaRk StAr oO]

a lot of guys in the Supra board spray in ther IC's.

[larryd]

yes it can be done but but your just as good just shooting a 50 shot single fogger before the throttle body.its going to have the same affect..if your looking for something to just cool off the charge rather then create more direct power like nitrous does, then look into water spray for the intercooler.. they make water injection kits and water spray kits

[Oo DaRk StAr oO]

I think squeezin would be too much for the celi.

[celicauk]

I reckon 50 shot would be too much, the only reason for doing this is top cool the charge so a 25 shot should do the trick nicely.

Water injection is a better idea though, then you can also have the nitrous for a real kick rather than cooling.

[Oo DaRk StAr oO]

What about 8psi and a 25 shot .... Rods and Lower comp pistons. What about getting a custom block guard?

[larryd]

like was said.. if you want more power, run more boost.. if you want to cool the intake charge look into water injection

[Oo DaRk StAr oO]

Oh no I mean Turbo with Nitrous.

[celicauk]

I wouldn't want to run more than 25shot with the turbo, don't forget that the increase in power is greater with FI than on NA engines.

Personally, I would go for 6psi and 25 shot nitrous, then you should be able to leave the internals alone, add to that water injection and you should be safe.

If you can get a block guard, lower comp pistons etc then up the boost to about 12psi, stick with 25 shot and that will be more than enough for this car.

[Oo DaRk StAr oO]

Hey Simon did they make you a block guard. I really want one!

[celicauk]

No, haven't gone this far yet. Once I get everything up and running and I am happy its safe, then I will be doing some more work on the engine so I can increase the boost, at that point I will probably do something similar to the work done by EIP, where they have sleeved the bores and fitted block guards. I also intend to talk to crower about a custom engine build up kit.

This is sometime off yet, so I would suggest you contact EIP and get there guard.

[Oo DaRk StAr oO]

Hey... i can get you rods from crower... they are doing a partial sponsorship with me. 700 bucks takes 8 weeks.

[celicauk]

Thats good, but I really want the full monty, crank, rods, pistons and valve train stuff, I am also looking into enlarged valves but not sure yet if the cooling/lubrication in the head is too close.

On the subject of Valves etc, I had a thought a few days ago about electronic valves, solenoids etc, would be pretty nifty as you would get continuosly variable inlet/exhaust, no timing gear etc. Just don't know how much the force the solenoids would need to exert to open the valves up. Just something to chew over :)

What is a block guard?

[Baldhead_J]

Am I reading this correctly and at least 2 of you have got your celica's turboed? I'd be fascinated to know all about the projects. Where did you have it done....specs..install, etc.

[oldster]

CelicaUK has a s/c and dark is getting a t/c.............

It's a big CNC machined piece of metal that fits down between the pistons sleeve and the outer block casing. It's designed to hold the cylinder walls in place so they don't shift under high stress (read: high boost) situations.

Due to the open deck design, under higher boost levels, the cylinder sleeve will begin to move, causing a leaky head gasket situation.

Hi guys. I haven't really been on this message board for a while. Anyway, if you want to run NOS and turbo, it would take some pretty expensive mods. You would have to bore out your engine, put titanium sleeves, new pistons, rods, cranks, head gasket, all new fuel system so you can reinforce it pretty good. With the titanium sleeves 30-40 over stock so you get even more power. Well, you can most likely set your boost to 20psi and set your nitrous to do a 150 shot. But of course, you have to have a lot of money or trust yourself very much ripping your engine apart.

Thanks, found some more interesting information:

Great info Oldster!!! thanks

Not too sure I agree on this, why would you want to overbore and sleeve in titanium? I know titanium has good heat properties but if the bores are that hot you have far bigger problems to worry about.

As for crank, rods etc, fair enough if you do overbore as there are issues with the cam lobes and piston skirt clearance.

To run a 150 shot and that much boost, these sort of modifications would be needed, I don't think Matt wants to go that far though.

As for ripping it apart and modifying it, been there, done that, got the free t-shirt :)

[Oo DaRk StAr oO]

Simon you still crack me up! I also dont quite agree with that. Also 150 shot phew maybe on a 2JZGTE. Im thinking more 15psi and 50 shot at the most. Ill be doing 8.75:1 pistons and Rods with a Block guard though for sure.

[celicauk]

:D Nothing like a bit of excess is there ;)

Let me know how you go on with the block guard.

Cheers

Im prollie gona get it done at EL Prototypes later on this year

yeah if you are just spraying onto the I/C to cool it down it would be a waste of money. I'd rig a water sprayer. IIRC www.dsm.org has instructions on how to make your own sprayer by tapping into the windshield washer bottle

I might buy a Water - Air Apexi one in the future and shoot a 30-50 shot.

No an air/water I/C is differnt that a water sprayer, spraying water onto the outside of the I/C to cool it down.

[celicauk]

I would suggest fitting an ERL water injection system would be more useful, this will put water into the cylinders keeping bore temps down, much more useful.

Sounds like a cheaper idea hehehee....

[celicauk]

They do it with a mappable controller too so you can have it vary injection rates based on boost, very cool :)

[celicauk]

BTW - No pun intended :)
