Test pipes will cause you to lose some boost pressure in the cylinder. We have seen around 10-20 whp losses with HFC's and Test Pipes.

will this change with your high performance kit being tested or will it be better with HFC's/test pipes with higher boost levels from the supercharger?

You think I should go back with HFC? i do have a 3" a am exhaust. I don't know what to do!!

he's saying with the stillen supercharger kit, it works better with more back pressure, so going from test pipes to HFC probably won't make much difference, the 3" exhaust won't be helping with this either, but remember, don't judge your dyno numbers vs other peoples, every dyno is different and will read different figures.

the only way you can truely measure your gains is on the same dyno and roughly the same temperature during your runs, you would need to do some before and after, but again the money you spend to change parts, probably isn't worth the HP you MAY gain, there is no guarantee.

I was running HFC's with my Stillen SC and recently went back to the stock cats, results are much better now. Car is running great.

diego@vossen · 07-28-2014, 12:10 PM

The Stillen kit is awesome, just don't go outside of all their recommendations like swapping the Impeller and running Test Pipes. With all the basics and a good tune you're going to enjoy it.

My current setup consists of the Stillen SC with the supplied 600CC injectors and stock MAF with a 9PSI pulley. I added the 25 row oil cooler and currently running the stock cats with a Meisterschaft Catback exhaust.

I won't do anything else except swap the injectors for 1000CC with UPREV GT MAF and a re-tune but that's as far as will go.

Really have to watch the AIT at the manifold, it goes up really fast even if you're messing around. After the car is warmed up (heatsoaked), it can go up 30 degrees during quick 2nd gear pull.

I can see why people are blowing motors during drag races. Too much heat causes detonation. Can't really push it when it's hot outside otherwise you're asking for trouble. If you don't have a vented hood, sitting idle or just turning off the engine will bring the AIT's up beyond the heatsoaked temp. I am seeing around 140 degrees when the car is warmed up. Oil at 180 and trans at 180.

Need to vent the hood or upgrade the heat exchanger.

100% right, I had both

I pushed mine all day yesterday with the temps and humidity in the upper 90s and it never missed a beat. I do have meth injection but it was acting up so I didn't use it at all.

Team_STILLEN · 07-28-2014, 04:57 PM

I think if going with a bigger/more efficient heat exchanger makes you feel better or make a difference (I haven't seen documentation so I can't say for sure) there is no danger in that mod. You're not changing anything to add pressure or stress to the system.

We will be test out our high boost kit soon and will see what the limitations and issue are with the kit as is. If the heat exchanger proves to be an issue we will include one with the new kit or offer it as an upgrade.

Hey Mark,
There is actually I thread on here where it showed more WHP with the frozenboost heat exchanger, it was one of the euro guys VLAD!
He did runs without it and runs with it, he had gains thought he power band .

Interesting, do you have more info. about the new kit ?

diego@vossen · 07-28-2014, 05:52 PM

Hmmm maybe when I swap injectors/UPREV Sensors I will add this as well. More cool never hurts

I can't find it

Why not offer it with the SI impeller ($365) and the 8 psi pulley? 2-3 psi gain at the same rpms. What do you gain from changing out an 8 psi pulley for a 9 psi pulley? 12-15 hp?
