Jim Wolf Cam testing for the VQ37VHR -- Results inside!

ban25 · 07-22-2016, 01:55 AM

My engine is done and the cams are in. Car's on the dyno, ready for break-in. Won't be long now...

What other mods do you have? Are you doing everything at once or adding cams to existing breather mods?

F.I. LTH, Stillen Gen 3, engine is from Rebello Racing (VQ37VHR, 11.5:1 compression, JE Pistons/K1 Rods). Also have 3.9 final drive gears with an OSG LSD. EcuTek tuned. Haven't decided on catback yet. It's being done all at once. Previously, I was doing 286 rwhp with EcuTek on 91 with an otherwise stock car. Will be interesting to see what it does!

What where your previous torque numbers? Because that's the real star of these cams.

Oh man, cant wait to see these results.

240 lb/ft. Here's the old chart:

OOOOO interesting. You getting tuned on 91 octane? will the dyno number be a little skewed because of the 3.9 gears ( this is for all the people who care about numbers).

Tuned for 91, but it's aggressive. On the track, I run 101, and I have a six-pack of Race Gas additive for the rare cases where I can't get 101 (like Auto Club Speedway). Definitely want to make sure I don't have to buy a fourth (!) motor.

that was more or less stock (not counting suspension etc.)? The new one is going to have LTHs, cams, and intake? Nothing else?

Yep, all stock except for suspension and oil cooler. The new one will have all that, and higher compression (11.5:1) and a new exhaust to mate up to the LTHs -- haven't decided which one yet, I'd like to get the F.I. one, but it takes too long to make.

Also, the 3.9 final drive will skew the new dyno numbers a bit.

Ooh, good catch!

Any idea when you'll have her on the dyno for a tune? Were the pistons expensive? I wonder how much of a difference the higher compression makes.

I don't have a cost breakdown for the individual engine parts, but the whole thing was $6400. The main goal is to create a highly reliable track-oriented build. Hence it also has the CJM oil pan, road race pump, and eventually I'll add the RJM oil pump gears.

It's on the dyno now for break-in, so I'll have numbers soon, probably next week. Starting from my previous EcuTek tune, we had to adjust the throttle table down a bit because it was too twitchy with all the extra torque.

I'm assuming you have the stage 1 cams How does the engine sound? Is there that 'lobe lobe lobe' noise some cars with cams have? a video with audio when it's all done would be great if possible.
