Is a JRSC too hot for roadtrack racing?

[tze]

Hi ppls

I was wondering if any of you feel that a JRSC application at 6 or 8psi would run too hot in continuous track lapping?

Not drag racing but road racing?

or should I go for a low psi turbo instead??

THanks!

Donno for sure but I will be able to answer this question on July 17. I will be at TWS (texas world speedway) and will be doing the 2.9 mile course. It is a 2 day event and will certainly know if the base kit can handle such abuse. I can't wait to be there that is for sure.. I see it now..

130mph on 45 degree banked turn.... YEEE HAWWWW !

I would think that you would have to run water injection to do that successfully. The heat is going to kill you after a couple of laps... trust me.

I already did a 2 day school at TWS in 1999 and had no heat related problems at all. The car did great and I passed most cars on the track. I was passed only by a modified 911 turbo two times over the two days.

Have fun Alex! I'll be in NY that weekend. Learn from my mistake. Get a helmet with a visor. Don't "sandblast" your corneas like I did when I took an off-road excursion!

Not hot at all. I just finished a day of driving lessons at a local road circuit here in the Philippines.

As you know this is a tropical country with avg. temps in the 90's. I have a JRSC in my B16A engine with a low temp thermostat. I went about 15 continuous laps in a 1.75 mile track with 3 people on board, and A/C running at full blast all the time. Them temp gauge didn't move, radiator never boiled over, and the reservoir tank level never rose.

Pretty good I'd say.

The problem isn't engine coolant temp, it is combustion chamber temperature. During a track event the chambers will reach stabilized temperatures (much more harsh than a regular drag race) which with an already marginal fuel system could spell trouble. I wouldn't run a non-intercooled forced induction setup on the track (and certainly not water-injection), and I would make sure to have a very fat tune before doing so.

tze: whaz UP!--hey foo, da suckas that i put they JRSC in be run'n they heaps in 2-day autocrosses and some road racing shitz and no dumbazz drag'n for a da whole f--k'n season wid no f--k'n probs!...and its on 6psi--believe that. da boost aint constantly on like some turbo nonsense...heat'n up yo engine internals all night/day!--intercooled or NOT.

SC SiR: whaz UP!--damn, ya run yo hoopdee in the Phillippines in that heat?--shitz! what kinda low-temp thermostat ya run? (Mugen?) hey, foo ya notice it be reducing da temps way lower than wid da stocker?

peace.

GSRMatt:

I was running RC 370cc/min injectors and was tuned to be richer than ideal. I didn't have time to tune it properly so I decided to err on the safe side. The A/F meter was on rich all the way.

Code:

I'm using the Mugen thermostat. I never really took a baseline reading on the stock thermostat, so I can't answer your question accurately.

What I know is, with the temps here, the low temp therm pratically remains open all the time. I wasn't sure I needed it when I got it. It was just good insurance.
