Last dyno run here at MAC Autosport in denver (pre blowup) looked like this.

317hp /251q

380 ish hp at altitude probably right at 400 at sea level. (The dyno run was at 5000 feet MSL)

Mods on rebuild that might affect power are:
-IPP heads with V1 JWT exhaust cams
-Harmonic dampener
-Jet hot ceramic coated exhaust manifold and test pipes (might help evacuate exhaust?)

(I'll edit in most recent dyno sheet here in a few minutes once we get her dialed in.)

Can't wait to see what the fruits of your labor bare out!

Before rebuild and after with JWT cans

17 hp
7.6 torque

Is this before or after tuning? Not a bad gain but I was expecting more with both the heads and cams considering all the previous dynos with them.

Then again, I'm pretty sure the elevation is playing a significant role as well.

Before dyno had full bolt ons gen 3 CAI z1 400 hp kit cat Berk cat back etc

The 17 hp and 8 q is just the cam. Also the motor hasn't fully broken on and settled (159 miles since rebuild so it might smooth out a bit.)

Remember this is just the V1 cam.

The tuner (Nick) sees a lot of vq37s and said this is the strongest na z motor he has seen.

I suspect 20 -25 hp loss due to altitude and 20 percent drive lone loss so I calculate about 418 hp. That's pretty solid.

Good numbers! My engine ended up right around 335 hp / 290 tq on 91 pump gas. That was with 11.5:1 compression, V1 cams, FI LTH, and Gen3 intake (vs ~286 hp stock). One of these days, I’ll see if the new owner can furnish a dyno on 101 octane.

One day I'll dyno it at sea level on 94 octane (and put in a sea level tune). I hope to see 350 whp if I do, but really the numbers vary from dyno to dyno.

This is a solid engine and feels pretty good up on the mountain roads. (It has gotten louder and definitely needs a new or at least repaired catback to rid it of an annoying buzz harmonic. Aside from that I think she is pretty well dialed in now.

Ordered new thermostatic oil cooler bypass plate today. (This one has bigger an fittings for better flow)

(My previous one was contaminated with engine shrapnel.)

Also the IPP installed oil powered hydrologic lifters are knocking a bit as they work out air pockets on start. I’m trying to figure out if that is going to be an issue.

Check the o-rings in that plate! It's one of the reasons no one buys mishimoto parts. Big thread on it. :eek:

Thanks!!! I will.

I went with this inline one instead (except with AN fittings). Required to make accusump work.
