Gen 5 3.0 Whipple First Impressions - 968HP @ 25PSI

I just got my car back from Pro edge tuning and all I can say is holy shit. Its been a long journey and 3 motors later, but I'm finally happy with the car. First I windowed the factory motor after a freak accident with road debris. Second motor made good numbers (920 race gas,805 pump)on the dyno, but I couldn't live with the piston slap,so I built another a little more mild or so I thought. This one makes 966 race, 801 pump (Anyone that knows Bill's dyno, knows it stingy). Both motors are built.Differences are 5.8 old 5.4 new, both heads ported but 5.8 has 1mm oversized valves. 5.8 has jdm ss cams, 5.4 has bullet cams spec'd by pro edge. I had a whipple gen 2 on both motors, but got the gen 5 for the new motor. I initially ran the new motor with the 3.4 and the car felt good but was a little lazy until it got spinning. I didn't have that setup on the dyno but I can definitely say that it feels stronger. It has plenty down low and keeps pulling up top. Just putting around it drives like stock, so far the roval works great. I have 2 learn how to drive this car all over again, but so far its fun.

Wow.

Awesome man. I have a Gen 5 on my Cobra and its a totally different animal than it was with the 2.3L TVS.

Here's some underhood shots, I've got to rework the catch can. They dont work. There was all kinds of oil in the old 3.4 when we pulled the throttle body.

I'm still getting used to it. It really hits hard through the whole power band.

Catch can breather may be the way to go.

That's what I'm looking into now

Whipple 2.9 Gen 4 pics attached for fitment comparison. I wonder if the Roval throttle body will clear the larger brake fluid reservoir of the earlier GT500 models? I also noticed that you have aftermarket fuel rails installed (what brand?) with the OEM EGR valve.

Installed mine in January but no dyno numbers yet; I would be pleased with 700 RWHP (SAE) with stock long block, manifolds, and cats on 93 octane. The little driving I did do felt noticeably stronger and torque came in earlier than my previous Whipple Gen 2. Unrelated to my Whipple install, my clutch took a dump and is at Spec right now for a rebuild. After reinstallation and proper break-in, I plan to get my car to my Tuner for a slight tune revision and dyno.

Looks great. Those inline catch cans didn't work well on my car either. Still got oil all over the intake and intercooler. I have a catch can / breather set up as mentioned above and it works a lot better.

Looks greats, thanks for sharing the pics. Is that a cobra jet 140mm maf? With a custom made pipe? What size pulley are you running?

Bad ass OP... makes me miss my GT500.

Can you shoot me a message about your catch can setup? I just pulled my factory supercharger and the catch can seems that it could use a little more help.

I had the same issue with my setup and the jlt catch cans, so Van @ Revan told me to run the Peterson Catch Can setup which can be had on sale here...
PETERSON CATCH CAN KIT w / LINE
You may need to get a longer rubber hose as I did. Unless they updated it

This is my catch can setup from Fischer Motorsports damm didn’t let me upload

Theres more room than there was with the elliptical on there. Fuels rails are division x. I got the kit from lethal.

Did not know you are running the KB 3.6 L/C supercharger. That KB 3.6 Mammoth inlet manifold is got so much flow restrictions (the inlet portion where the short turn radius, the EGR depression walls blocks 50% of the RHS rotor, and the inlet tunnel design was not maximize for better flow).
