i made slightly over 500rwhp with 7.5psi, stock internals, new pushrods, patriot duals, TRT '"special cam" ported and coated stock manifolds and heat wrapp from manifolds back to turbo

love the kit, but im going to learn to weld and bend metal in a few months and make my own front mount

I'm just getting caught up after being away from the board for almost four months...

Got some dyno numbers this past weekend on my setup. 407 rwhp on 5 psi, and 543 rwhp on 11 psi. I'm running a low-comp forged engine (8.7:1 with the current heads).

Horsepower was 475+ from 5300-6900 rpms and was still holding when I let off.

The turbo is the 67 upgrade, which was further upgraded to a "70" equivalent by Forced Inductions, during a rebuild after an unfortunate smelting accident.

Added an obx intercooler, and a bov. Upsized the piping where possible using gobs of thin wall aluminum tubing and silicone couplers. No maf, 2-bar hptuners, lm1 wideband.

Single walbro pump, 60 lb mototron injectors, stock lines, stock rails.

224/228/115 cam, ls6 intake, first generation TEA 5.7 heads unmilled.

Mid-length mac headers, nothing wrapped, Borla xr-1 muffler after the turbo.

what ar. housing are you running?

Hot side is .81.

I couldn't find a number on the cold side. That's the side that has the custom wheel and housing that Forced Inductions put on during the rebuild.

.81 gotcha. hows the spooling in the lower rpm's? ( you said, no wrap and mid length headers )?

Going from memory here, numbers based on reviewing log files from my scanner a few months back... Was logging all the usual stuff, including tps and map, so I could see the elapsed time from 100% throttle to max boost.

Some boost comes on immediately, full boost around 1.6-2.0 seconds later, depending on load and rpm at the start of the burst. It has a nice linear feel to it, not a gap followed by a sudden onset.

I'm ramping in fuel, and ramping out timing, as the boost builds. (instead of just suddenly switching from na fueling and timing, to boost fueling and timing) That helps too.



Also, it's an automatic, with a 3500 stall, so I don't have a _really_ low rpm area to deal with.

Nothing wrong with Bob@EPP's link at all. If you click it they made GREAT POWER and had great success with an STS kit on that camaro.

Our Sponsors can post up links to their work when they want, nothing wrong with showing off to a potential customer.

I dont think he was trying to be a ***, but that link just shows some ups and downs of a sts kit. I look at that link alot during my build

More ups than downs to say the least.

I never said he was trying to be anything, but I beg to differ on the "message" he was trying to convey.

Here is a link to my T/A on the dyno. You can really hear the turbo spool up, and the wastegate open. You can understand why it scares the hell out of the import guys around here.

i love mine, i put some extra time in it making it nice and neat. dont cut corners and do all the upgrades and it will work great. drove mine all summer 7000mi so far and no probs. changed to sd tune and made 500rwhp 520rwtrq at 9psi. it will go sideways at 60mph!! this thing scares me!! here is a vid of me doing a burnout i could have went further but i figured 300' is far enough enjoy. http://www.youtube.com/watch?v=lEMgHkh62RI
