Buddy,
I like that!

Oak, we had (4) run groups at Road America and about 40 cars in
each run group. I was in the fastest run group (and probably close to
the slowest in the group). I was on street tires and my straightaway speeds on the two long striaghts did not indicate any kind of significant loss
of power over the course of a 20-25 minute session going ***** out.

mk, thanks how do you think it would hold up out west, desert condition +95 degree plus +140 asphalt. even when almost stock I could feel heat soak robbing power. all day track sessions long sessions as long as you like.

just wondering how a mod at your extreme would handle this. by your claims your mods will withstand better than stock. would you say so?

 

Oak,

I ran 1.1 bar all weekend with monstrous intercoolers and A/F ratios in the
high 11's.
I am not even close to an expert, but before, with my PSI 480 kit ran 1.0 bar
and had the undersize (for serious track work) stock intercoolers.
I would like to know the facts also to see what types of stresses are caused by this type of system (and so much torque running thru it).

I do remember hot days at brainerd in my 993TT (which really suffer heat
soak) and power was severely robbed within a 20 minute session (10 laps).

I often do not run the whole session (at my home track of Brainerd), I
quit when I am ahead. I am not the guy out on the track on the last lap
of the last session, going 10/10ths.

Cheers, good discussion
and I do remember that the GT700 kit did not include intercoolers at one time
and THIS would not be a good idea. I do not know if they are now part of
the $28K kit??

you are running 628 WHP at 1.1 bar???!!!??!?!!??! wow that is pretty damn impressive!!! SH** I knew proto was good but Sh**!

 

Oak,

You were arguing pretty strongly a while back that stock IC's were not susceptible to heat soak, right?

I ask because we mean old men need to stick together, and I am a big fan of upgraded IC's.

 

Newbie here needs an education. Does the motor have to come out of the car for the plenum install? Do the silicon hoses produce heat soak?

 

EVOMS GT700 kit does not include the I/C or throttle body in the $28K
price tag. $ 33,245 includes larger throttle body and Intercoolers.
Wow that must be interesting with the stock intercoolers !!!

628 whp=1.35 bar

 

You just have to lower it. The silicone hoses are not suppose to swell like stock hoses under high boost but have never heard of them producing heat soak.
