IPS Twin-turbo L99 *Preliminary* Dyno Results

Car: 2010 L99 SS
Mods: Stock w/ Corsa Cat-back & IPS TT Kit
Turbos: GT3076R w/Billet Upgrade (Smallest we offer)
Wheels: BIG lol (22" Asanti)
Air: Good (85 Degrees in the shop but much lower humidity)
Numbers: 568rwhp / 575 ft/lbs

We won't be done tuning the car 100% until next week (Everybody left late last night for the LS-Fest in KY this weekend) but here is what we have so far. It is interesting that the car is almost 100rwhp under our LS3 TT car to the number thus far. It *Seems* as if it is not making the 8psi the LS3 car was but we have not done a test yet to confirm.

These GT3076R turbos are REALLY responsive! You can cruise through the parking lot at 2% throttle and hear the turbos whistle. The larger GT35Rs don't get into boost as easily so you don't hear them as much off-boost in comparison. The car sounds awesome! Traction is impossible with a 1/2" side-wall on those big 22" wheels so the car REALLY needs a set of DR's before any aggressive street-driving could be done safely

Intake-temps peaked at right around 100-degree's which was 70+ lower than the Maggie 2300 SS and Edelbrock E-Force we tuned right before this car (For comparison).

Tuning will continue next week and I will post "Final" numbers then. We really wanted to see 600rwhp with just the TT Kit but time will tell I guess

That still better than a lot of other L99 power adders on the market. Enjoy LS Fest. Sounds like you guys deserve the break.

These kits make more power than anything on the market. I know where my money will be going, I always been a fan of twin turbo.

I didn't post up a graph yet but yes, the numbers are SAE-corrected

I am hoping we can get a little more out of it on Monday so I will post the graph up of the "Final" numbers then

So........How did you get temps on the Maggie up to 85 degrees over ambient? The most I saw on back to back 30 to 120 runs (private airstrip) was about 40 degrees over ambient. IAT's peaked at 135 on a 95 degree day. They recovered quickly to about 10 degrees over ambient under normal driving conditions. Maybe vettes run a lot cooler. My maggie mp122 sees temps like that.....not so with the TVS.

They got to 168-169 degrees after 2 dyno pulls. I would assume that the airflow into the heat-exchanger is significantly better at 100mph on the street than what our dyno fan provides

Power at those IAT's was stuck at 450rwhp (+/- 2 or 3 HP) while dynoing it completely cooled down resulted in 496rwhp with no other changes.

That just tells me you have the burning (literally) need for a bigger fan in your dyno room

no they just need a bigger dyno room! (if I recall they are in the process of moving to a bigger building).

I know when I was there, that room was over 100*F!! (at least according to my dyno sheet and the temperature reading in my camaro)

Don't kid yourself, that is a very important factor. For the engine dyno at NRE you should see the sick setup they have. When you first crank the fan(s) the lights dim for a few seconds. It exchanges the air in the dyno room every 6 seconds... Feels like you are in a storm.

Quick under shot, showing again how our system completely fits above the factory subframe

We should have the final numbers on this particular car with in two days.
