Finally finished the first stage of my build:
2.9 Whipple
3.75 pulley (10 psi)
VMP IAT2 Harness
JMP Dual fuel pump booster pump
ID1050X injectors
Redline adjusted to 8400RPM (keeps the 12:1 ratio)
KOOKS headers and mid pipe
Corsa Extreme Mufflers
Tuned by LUND RACING
93 Octane 770 WHP
E85 820 WHP

Next mods:
Crack open the engine and upgrade pistons, Rods and Cam
New fuel return system
Smaller pulley
Should make 1000 HP easy (currently making 943 to the crank)

So, one of the things I am super curious about is how this would compare to the GT500 setup. Although we know now that the GT500 is most likely going to run a cross plane crank, like the 5.0's. I find it a little interesting they are taking this approach. I had a 16 PP GT and one of the things I like about the GT350, is that there is no low end torque. I'm running only 3/4 gear on the track (occasionally 5th on the straight if I'm hitting my line well). To me, coming out of a corner and not having to worry about the back end slipping out on me, is amazing. So if throwing a power adder like this on the flat plane nets the same power without the low end torque issues, why would they go to a cross plane? And with the mid engine corvette going flat plane as well, im just curious where the line of thinking is coming from. Maybe there is something subtle I'm missing here. I hope so.

The main benefit of the flat plan crank is higher 8200 RPM. Horsepower is a function of torque and RPM, so horsepower can be made with more torque, or higher RPM. A supercharged (or any forced induction) engine makes horsepower with torque, and adds heat, and does not need the higher RPM - and would spin the supercharger too fast in the upper range. So a cross plane works just fine in a supercharged application - more torque, does not need the higher RPM. Look at all the cars that have replaced larger NA engines with smaller turbo ones like most Porsches or BMWs. The new smaller turbo engines have similar horsepower ratings have lower redlines, but make more torque across the power band. Same concept here - cross plane is fine for forced induction.

I also have a whipple on my gt350. I would love to talk to you about your LUND tune.

Thanks

I see a Mekur XR4TI in the background!!! I wanted ones of those in 1986 when I gradated, but no dice on insurance

Lotta Whippled 350's out there!

I saw this one at the Shelby Show last month in Dallas. Whipple can really dress out an engine room. I just wish you didn't have to change motor mounts and lose the shock tower brace. Maybe someday! ;) Vehicle Hood Motor vehicle Car Yellow Car Vehicle Vehicle registration plate Automotive tail & brake light Hood
