Can anybody tell me how much power the stock internals can take on a 93 uk tt, and how how much boost can you safely run?

:D

Ignore that :)

Brain not working today!

intake temps were at 70c, but now down to 60 with the larger intercoolers

 

(readings taken just before the throttle bodies)

 

They said that it was perfectly safe to run but they would like to see the temps down at 50c. Did also say that it would be better on the road as thier fans were not all that effective.

How much higher was that than the ambient temps?

Well it was done in jan 07 so it was about 5c outside.

 

Turbos seem to be kicking out some heat, heating the air passing through them a lot. Its then cooled to about 60c before hitting the intake as thats where it was measured. Bigger ic's did help and got me a 15hp increase and a 10c air temp drop running the same boost as before.

 

They only had a smallish fan and the bay door was closed. Said the intercoolers should do a much better job when being blasted with air while out on the road.

 

So yes, its possible my afr was lowered by a warm intake but I cant really measure it while running on the road to be sure.

 

Do you think I could fit a sensor on one or both of the intake hard pipes to measure the air temp on the road? Shouldnt be too dificult.

IIRC they should only run around twenty degrees more than ambient temp.

Might be worth me looking into a temp sensor for the intake then as the intercoolers were not cooling as much as they should on the rollers. It could well have been down to thier fan though, i remember now that the problem was getting the fan pointed at both intercoolers as they were so far appart, he had to move it back and center it meaning the air flow into the coolers was not as much as they wanted.

That would be good, the lower the charge temp the more bhp, if you haven't modded the fuel system it may be an idea to check the FPR is in the correct range as well?

Yeah I quite like the funky fp gauges in the engine bay, might invest in one of those too.

 

the car made a healthy 380hp with a good afr so I'm not too conserned, I might consider going even larger on the intercoolers though.

What ICs do you have?

 

You just need one test on the fpr to see if it is working.

uprated ebay ones, bigger than stock, ally end tanks etc but not as big as the godspeed ones
