2.9L Whipple Twin Screw - SNEAK PEAK!
Being one of Whipple's largest dealers for Ford and GM Systems (primarily the 2010 Camaro) we wanted to share this sneak peak of the all new Corvette system currently in the final stages of testing. The system features Whipple's 2.9L compressor with a gear driven rear and efficient front entry system.
Compared to a 2.3L TVS Magnachrger on a 2010 Camaro LS3, the Whipple made 35rwhp/27rwtq MORE with lower inlet temperatures at the SAME boost level.
We are excited about this kit and happy to share the pictures. Due the taller height of the s/c case an aftermarket hood will be required. The shaft will be covered and quite a few items will be more detailed/finished similar to the Camaro kit (pictured just below on our customers car)

Either way, INSANE power from these kits. They will be available in 3-4 weeks and we have the first few kits coming to us!!

I am assuming this is a dynojet and STD numbers because no way it was SAE with stock exhaust. We did one at 9psi, using the stock airbox (how the kit comes) and long tube headers and made 575rwhp on our Mustang Dyno, which is just over 600rwhp on a Dyno Jet SAE corrected WITH headers

A local guy here in St. Louis has a Whipple with the pulley that comes with the kit. He did a custom cam (223/231 .611/617 115+3), and already had headers and some aftermarket cold air. The car did 627rwhp/550 ft-lbs of torque STD with zero smoothing. Even corrected to SAE with smoothing on 5, it was still clear over 600whp at peak with a gut punching torque curve. Like every other LS engine, they freaking love fuel. I ended that car at 11:1 on pump 93. The car took back to back dyno pulls without excessive heat soak too. I was impressed.
Do you know what boost the engine was seeing? The pulley that comes with the blower is 9psi and an aftermarket cold air intake will add 1-1.5psi of boost but that camshaft should knock off about 1-2psi, so this would be right around 8.5-9psi.
11:1 AFR does not really mean much - what are you assuming is stoich? Tune in Lambda, much more accurate. An engine will always make max power at a Lambda value of .820-.850 but it is impossible to run the engine this lean on pump gas with boost.
We tune all boosted street engines between .77-.79 lambda, which assuming a stoich value of 14.05-14.3, would be in the low 11's. To a certain point, the richer lambda will allow for cooler combustion temps and some additional timing
Anyway, back on track. GO WHIPPLE!

Not to side track the thread about the amazing blowers, but STD numbers are about 4% over SAE so this setup would be about 600-605RWHP SAE on a dynojet, which reads about 3-5% higher than a MD (depending on the setup)

If you want to talk in terms of lambda (I use AFR because most people don't understand lambda), it was done at 0.75 lambda. I tried it a little leaner, but it was getting sensitive to spark knock and didn't want to take as much timing. I made the best power on that setup at 0.75, so that's where I left it (owner wanted to make sure it was very safe, too). I started off around 0.78 and tuned for MBT, then picked up another 20whp without even touching spark when I dropped it to 0.75 (no cooldown).
For what it's worth, I dig Whipple's pump booster for the Camaros.
I'm trying to convince my friend who is getting an LS2 C6 to get a Whipple setup once he has the car. The low end torque is just stupid.

Using a ZR1 MAP sensor, it peaked just under 10psi, but was around 9psi for most of the time.

Do you have a part # and price for the 2010 LS3 Corvette Whipple kit?
When will it be available to order?
Do you think it's compatible with the NW 102 TB, if one was to use an aftermarket air intake?

# Integrated Crusher ™ 112mm round inlet outflows smaller 90 and 93mm inlets such as other Eaton based systems
# Integrated Crusher ™ 112mm round inlet for optional 102mm, 105mm and 112mm TB's that outflow others 110mm
Aftermarket intakes will also work (may require light modifications) as this is designed to use the STOCK intake.
We are taking pre-orders now (with a small deposit) and pricing is not yet set but I will try and get more information from Whipple today but I would expect it to be around $7500 give or take plus the cost of the hood
I will get exact flow data from Whipple, but on 5.4L Shelby's we have made 750-800+RWHP without issues and still lots of room to go. The 2.9L has a 1800CFM HP capacity (roughly 1200HP)
Give me a couple of hours and I will get some more info
