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.

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

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.

yeah I hear what you are saying, it's going to be easily over $2k for the upgrades, no idea on HP gain really at the end of the day.

only kit I can get here in Aus is $10.5k and it's basically the exact same as the original GTM stage 1 kit, which for me is just way overpriced, none of the other US kits will fit the RHD setup. So would really have to get someone local to do a turbo setup, aka guinea pig, which I really don't want to be around here.. so unfortunately it's kind of do these upgrades or nothing really.

I am almost 100% certain your stock engine will not lost long if you upgrade that kit so here goes another 5-7k. Enjoy the car mikey, the headache and agony that I went through when my engine went and thousands spent was not worth the little extra power.

He's for sure telling the truth, If I could go back and do it again, I'd left it alone at 412 WHP. The 457 WHP for 3 days wasn't worth the upgrade cost, the 9 months after I didn't have the car and all the $$$ I lost.

Z&I · 01-06-2015, 03:48 PM

Mikeeeey !!!
Everything we have been saying is true ...

I dyno'd at 483 whp after the $k$$$'s upgrade ...
Made only 63 whp over the original Stillen kit (420 whp).

Gained only .1 sec at the drag strip - that's Point 1 sec. !
Only made the one run before the motor left the building.

I'm again without the car looking at another 9 months in the shop. More Time and More Money.

Had I to do it again ... I would have Built the MOTOR the right way in the first place, instead of Bolting on.

haha all good guys! I'll take your advice and just leave it alone!

jwick · 01-07-2015, 08:31 AM

Hasn't it been proved over and over again that you should never upgrade the Stillen SC?

Pretty much. More boost= more heat that the ecu doesn't know about= blown motor.

Put your hard earned $bucks$ first into a built motor and then you can do what you want to do :-)

Did some more checking : Seems our cars have BOTH MAF and MAP sensors see STILLEN pdf page 15.
What Gives ??? How does this all fit together ???

Another article states that some MAF’s have incorpated an IAT into it’s construction.
Is it possible to electrically separate the IAT from the MAF/IAT and ‘wire in’ an IAT post IC ?
Is this feasible?

I have an email in to UpRev concerning this question …. waiting waiting waiting.

BTW – Do you Turbo guys ever blow motors ???

Below are some useful links:

Yep, we've got both a MAP and MAF. From my knowledge the MAF provides the IAT data, hence the problem with the Stillen plumbing. No idea if you can unmarry the two. Turbo guys blow motors too, but it seems the Stillen kit likes to detonate at a far lower power level than guys run with no issues on turbo setups. That's why I'm almost convinced that it's because of bad data from the MAF since it's pre-compressor. Lots of factory FI cars run a draw through MAF setup, but they're tuned by the manufacturer to account for it.

Awesome !!! now on another journey to find out how the MAP is being utilized.

Now looking to send out the Frozen Boost and Stillen Manifold to the radiator shop to braze in some larger ports ~ larger hoses ~ a 12" fan in front of the heat exchanger ~ and replacing the Stillen kit Bosch circulating pump with a larger flow aftermarket (Mercedes) one.
By Golly, we'll get some COLD air in there for sure !!!
