So just ordered my Stillen SC

gussyturbo z

Hey guys now you got me thinking!! I have the frozen boost on mine and my intake plenum temps are 47 degrees. It was 45 degrees today in texas the car was running really good it seem. Is that ok? Are you guys saying that you blew your engine with frozen boost? I'm confused..

ANMVQ had upgraded to the frozenboost heat exchanger when motor popped.

clkio was still running standard stillen heat exchanger when motor popped.

They are talking about moving the MAF's which are currently before the supercharger to a better location as the temp probably changes between where it's measured and where the air ends up entering the engine. Not sure where the best location would be though.

Anyone ran a water/meth kit also?

clkio

I am currently working on it. I am really excited to see how much she will put down after meth as my engine is very low compression and my tuner doesn't think it will help alot with power. My engine spec
HBR performance built VQ37VHR Bore 3.7805 Stroke 3.460 Wiseco k643m96 dished 8.5:1 Pistons, Wiseco 9600 XS Rings, K1 Billet 4340 Steel H Beam connecting rods.

Z&I

Like that Photo gave me a few ideas.
Looks like you used to have woofers and now you have drywall... :-)

I will be installing the AquaMist water/meth injection.
I have the 9.5 CR Carillo pistons and rods - race bearings and ARP bolts.

Will be posting all of the particulars once the build is satisfactory completed.

8.5:1?! holy hell man that's low. have you tuned the kit with the new engine build yet or still in the making? are you looking to go much higher psi than just the upgraded impeller?

clkio

You see mikey, I bought a used supercharger kit from g37 forums and the kit had all the upgrades done to to it (pushing 12.5 psi) on the stock engine, car was making around 480whp and 357 torque, I went ahead and installed the meth kit but didnt tune yet. After few days of driving with the supercharger, engine blew (before I got to tune for meth) so I found a great deal on the rebuild engine I have right now. Unfortunatly, car made less power 462whp but made 380 torque but still not tuned for meth. I will be running meth around March and see how it goes. If I am not happy with the setup at the end, I will be removing the supercharger, selling it and buy a TT as the built engine i have now is better for a turbo setup.

mikey1600

fair enough, thought you would have lost a lot of power going from 11:1 to 8.5:1, turbo setup sounds good, I'm still torn about doing all the changes to mine now, probably too much $$ compared to the gains. Still waiting on pricing back from vortech supplier here in Aus to do the upgrades

clkio

Out of curiosity, how much is this going to cost you? Dont get caught up with the numbers because uou are absolutely right about the $$ going to be spent vs the gains. Extra 60hp will cost you maybe 2000? Why don't you sell your setup all together to a turbo? The reason I ask is I bought the stillen kit used of the forums for $4k with all the upgrades done as well as walbro 340 fuel pump and 1000CC injectors which was the best deal at that time. Personally, I wouldnt put the money on rebuilding the kit since I am spending thousands, you want more power, sell the kit and buy a TT because the thousands you going to spend here will yield you a lot more gains than 60hp.

Z&I

A question for you'se guys in the know ...
Trying to figure this all out in my head (a very dangerous place to be I might add)

The Stillen charge tube splits at the throttle bodies ... and the difference in length between the 2 isn't all that much...shouldn't have that much affect ?

And I'm not exactly sure where the IAT is measured ... at the Stillen manifold ?

Anybody know for sure ???
Stillen are you there ??? Help ???

IAT is measured at the MAF, so any change in charge temp after that won't be compensated for by the ECU.

Z&I

Thanks Chuck ...
I thought so - but thinking about this too much introduced some doubts in my mind -
So ... moving the MAF's to the charge tube after the SC'r (if possible) still wouldn't fix it all since the air still hasn't passed thru the Intercooler ?

Is this correct ? aaarrrggghhh - another dilemna

I think I may have cross coupled the AquaMist instructions in here as well.
