morning all

just watching this vid from ten of the best

http://www.totb.co.uk/images/movies/movie-cdr_supra.wmv

and noticed he mentione dhe's got nos to the intercooler only, not to the engine.

does this help with cooling? and would it be beneficial on a scoob? looks pretty good too.

take it does what a IC wtaerspray should have done?

cheers

 

Would have thought that pure nitrogen would have been better on the intercooler rather that Nitrous oxide as nitrogen has cooling properties (hence why they probably used NOS).
CO2 may have been an option also

ahh okay, not worth te cost unless running big power i take it?

 

been thinking about this earlier..

would they be a way to do this with a TMIC?

as i was thinking an STI-8 IC is good for 400 bhp on a classic.. well 380 reliably say.. how hard would it be to get nos or the like to cool it down and make it good for everyday if you dont wanna go the front mount route?

good comprimise?

what you guys think?

 

ps. i think it would also look pretty cool steaming out of the scoop

 

I had this setup on my old type R a few years ago, it worked very well.
I used a nitrous express 10lb bottle filled with C02 and a cryogenics intercooler hoop, I fitted a charge temp gauge and you could see the charge temp drop from +50deg C down to -25deg C!

The car made 405bhp and 396ft/lbs on a dyno dynamics RR on pump fuel using a 20G

 

nice

how much did it cost to setup? and how long does a bottle last? how much to refill?

i think itd be good now and again for those times when your at lights and temperature rises.. as long as your not relying on it.

p.s. does it steam like in the vid?

 

Yeah, it does look good

to fill the bottle was costing me around a tenner a time and I got around 30 hits out of it.

I got the bottle and solenoid 2nd hand from a mate so it cost very little, the hoop wasn't cheap though, I am sure it cost me around £80 at the time.

 

Exactly. If you DON'T map for it then that's fine. The last thing you want is to be mapped for it's low temps... and then for the bottle to run out!

If it's mapped as a normal TMIC but then subsequently run with the NOS on, it'll give a nice bit of headroom against det due to those colder-than-mapped-for intake temps i.e the timing will never get to be 'on the egde'. But if the bottle runs out then - nee bother - as the car will have been mapped as if it wasn't present anyway, so back to status quo, regardless...

 

thats not bad price.

any kits available? or is a sort of do it yuorself thing? any pointers?

 

yeah thats exactly what i had in mind, extra safety as even when mapped for sti-8 IC , you'll be suprised how sometimes on a hot summers day, you can be caught out with high temps

 

Yeah, you have to be very weary when coming to a halt on a hot summer's day after a sustained high boost/WOT run. It's this classic scenario that heatsoak skyrockets. If you find yourself in this situation, DO NOT EVER be tempted give it beans from rest again (e.g at a traffic light grand prix lol).

But, of course, and as you say, this is where the NOS comes in very handy, as it pretty much stops heatsoak in its tracks (if it can achieve temps as low as MINUS 25deg C! ).

 

just been looking to these..

jonny_gav was yours gas? or liquid c02?

found this link .. Tuning | Car Modifying Parts and Accessories

this kit is liquid c02 but just looking at the selection there such as the air cooler and the fuel bar etc.. makes you have doubts.. like if it was so good why dont many use it?

anyway ive heard about nos/c02 on ICs before so i cant doubt that.. and youve used it with 400 bhp. just makes u weary..

 

wow! bloody hell didnt notice he said that, i misread it as +50deg to +25deg.. thats amazing if it gets it too -25deg!

 

Yeah, that's what NOS does - it super cools.

This why it works brilliantly in engines, and why all of a sudden you get a massive slug of instant power... because, in an instant, the ICTs have plummeted. Also, the Nitrogen content conveniently acts as a dulling-effect 'cushion' - helping prevent any det spiking through to the top the piston crown, through the rods and ultimately on to the bigend bearings.

If not set up correctly, though, it can have spectacular results i.e. read, huge blow-ups!

 

i like the idea of this, going to pass it accross to my mate instead of going front mount .. he's currently on the broder of sti-8 with 380 break..

think it'd be a good test

where can you get the nos kit from though?

think gas would look miles better than liquid.. but then again what works better? nos or liquid c02

 

Probably liquid CO2 - that stuff's mental! Do you remember the ol' leaf in liquid CO2 demo in Physics lessons? lol

Dangerous stuff though - handle with care (unless you're not too keen on your fingers ).

 

cool,

what happens to it when it goes on the intercooler? take it evaporates?

 

also anyone able to recommend a good place for the kits?

 

It was liquid co2 mate

 

what's cooler, NOS or liquid co2?

 

Liquid C02 Mate

Although Nos looks better lol with the steam, but hey its cooling your after, geta fake purge kit if you want that ..

still if anyone can recommend a decent kit, post up..

is the demon tweaks link posted the best place?

also anyone know where to get refills in the yorkshire area? (liquid C02)

 

Check this web site out they do nitrous kits, Cryo2 kits and the gas Automotive Supplies by Nitrous Oxide Supplies

 

i use a co2 bottle from my local paint supplier, 25 quid for the first bottle and then 15 quid exchange, and there just fire extinguisher bottles painted grey.and a solinoid from the local shop, but i bought the jets of the bay so it cost me about 50 quid for the full setup.

surly a front mount rather then a c02 setup on a top mount would be far more cost affective...

P.S. Was adding a NO2 kit to the 2.1 next year.......

 

looked like he was just purging gas from the system onto the ic for some cooling effect, but the prime reason for that is to rid the system of the gas so he gets liquid N2O at the hit,
nitrous systems use liquid N20 not gas
best place to look for a kit is Eurodragster.com. Your guide to Drag Racing in Europe put an add in the wanted section loads of second hand kits about,
you only need some nozzels/solanoids/bottle a few hoses and relays and your done
then its a case of when not if does your engine self destruct

 

1 - If you're gonna use Nitrous, you may as well plumb it in directly to the engine. Far more charge cooling and all that lovely energetic atomic oxygen in an excited state as the N2O dissociates, which can then create a hell of a lot more power

2 - Another option is to use 50/50 water/methanol in the conventional IC spray, and have the spray mapped for hard throttle/high temp use. That's what the Solaris ECU can do and that's another reason why I'm going to have one fitted soon

3 - The standard ECU can cope very well with temperature differences; if you use N2O or CO2 to cool the IC, (even unmapped) you'll get more power. If it runs out, you'll get less power - simple as.
