Thank you very much for your review!

Just a word of feedback: the system definitely does not creep. The turbine housing and downpipe design experienced some of our most intense development and testing to verify this. Rather, your tuner likely added wastegate duty cycle to modify the power curve (you'll note how your low boost curve is not as flat). There are possibilities in how the wastegate actuator is attached could be causing a mechanical problem, however it is likely intentional in the tune.

Sorry to hear you're thinking about changing, keep in mind the system is very expandable. You've reached the limit of 91/93 octane (which will be true for this system, as well as any other) however, we're putting out cars well over 500 whp with higher test fuel.

 

If you look at my signature. I'm running the Garrett gtx3576r turbo with the t3 open .63 ar hotside running 91 octane at 14psi of boost on a stock f20c. My dyno show that my power never flattens out and it keeps on making power to redline.

Do you think the small evo8 style twin school hotside has something to do with the top end power?

 

V8 .... Do it ......




























Do it ........



















Come onnnnnnnn ....................... Doooo itttttt

 

That's a very good point. Didn't we rectify a similar situation w/ my 30r setup? If i recall correctly, swapping it to the intended size ended up making a huge difference.

 

I've followed this whole thread and it seems like the same problem I have.....I've thought of going 4.44 gears, SOS S/C, now SOS TS MAX. The problem is that some people just want the whole damn world to explode when they put their right foot down. That's my problem, I love the S, inside and out, but I'm worried that even if I drop 6k on a stage one SOS S/C for my AP1 it just wont be enough.......

oh well time to go by a SR-71 black bird I guess

 

Just supercharge that turbo and be done with it already

You still never ran the 1200 to its full capability after everything you have done so far, which is sort of unfortunate, your attention span seems way to short. This doesn't really give you apples to apples comparison. You made 300trq/390hp on this turbo, but with a 3-3.2" pulley you could have made 300trq/450whp on the same 93 pump. If your looking for a faster strait line car, that would have been it, if not, well we don't really know what your looking for

 

im disapointing with the kit to much hope with it i really would like to see more than 400hp on 93 ( a couple do really more at the same boost ) i think its a good kit for low torque and DD but not for Highpower drag car , but at this PSI im looking for around 450 with nice curve up to 9K , never mind maybe juste wait to see a couple other review before start think to buy it on SOS website on the dynograph for GT3076 with E85 at 16PSI is only make 435 whp / 320 torq ??? i saw people make this kind of power on 93 but the biggest thing its the curve drop off hard at 7400 rpm think about if u got a 2.0 and power drop off to 9000 ?? i dont understand how this kit works ?

 

this kit was never designed to be for drag s2000s

 

My thoughts exactly...along with the very short runners on the manifold. Others seem to have confirmed this as well.

 

Yup.. I'd guess it's a little bit of everything. The #2 & #3 runners are very short and have an abrupt turn, definitely not good for flow. On top of that everyone and their mom is comparing this against externally gated turbos (that likely dump to atmosphere). That's a whole lot of flow that bipasses the turbo. It's unfortunate that it looks like it chokes a little on the top end, but like others said, the kit was NOT designed for peak power. I would personally be content with ~400whp on pump gas, but if you're looking to make big power, perhaps you ought to look at a manifold with a nice merge collector. Unfortunately there are trade offs for everything, and in order to make a nice/neat/oem like package, you can't have a merge collector.
