Hub dyno always reads higher than a conventional drum dyno, but I’m sure this car would put down a big number regardless.

The intake setup on the car will really shine over 120mph. So I have no doubt it will "make more" power on the street.

Whatever the case, everything went well. Motor is solid, made great numbers, and should last a long time. I didn't get aggressive with it in the tune. Actually took slightly less timing than the previous setup. Probably some power switching to a TR7 plug over the 8s I have in the car, but again, I don't want to get aggressive with it. yet, at least...

Not always. Really depends on the way the dyno is loaded. On these Dynocom dynos, you can really swing the numbers both ways. I did slower/heavier loaded pulls while I was tuning the car and then had the owner set it to his "normal" load numbers for the final pull.

I would say the heads and lift of the new cam contributed to most of the gains that were realized. Duration of this cam is slightly less both intake and exhaust. Compression was only .07ish more. Bore is .005" over.
Cesar wants to try to get more out of the setup. Kinda pondering what changes we can make, if any.

Missed this one. Its not the exact dyno I used but its the same brand dyno. Roughly same time of year. Shop was 100+ degrees this time, where the other shop was running the a/c.

Took the car out for a rip over the weekend. Had a few issues pop up but was able to get some data.
Seems like the clutch solenoid was somehow activating and cause the clutch to slip during the shifts. I changed the settings around to not let it engage over ~30mph and I opened the valve all the way, so even if it does activate, it shouldn't slip. If it continues to do so, I'll just pull it out.
2nd gear doesn't look like it will hook at all, with the gearing I have. As soon as I got into it, it kicked the car sideways. I'll likely be going back to a Z06 ratio trans and this should help "soften" that hit.
Ended up filling the catch can up on the first hit, which has never happened before. On the second hit I did, it spit oil out all over the pass side of the car. I moved the vacuum port to the front of the pass VC instead of the back of the driver side VC. I also let it engine brake after the pull and have a feeling that is why it filled the can, so I will no longer be doing that, lol.
Other than that, the car sounds great and feels great. Definitely some potential there once the bugs are fixed. I don't know if it will be as fast as I hoped but it will be close.
There's a video on my IG that I posted a few posts up.

Fwiw if you could get some kind of comparison on a dragy from 2.97 to 2.66 gear sets from 60-130/100-150 that would be doing a big service as well.
Car is going to give a lot of people a hard time.

Definitely heard the clutch grabbing hard on the shifts. Btw - time looks great factoring in how long the mph was still between each gear change.

For what that pull was, it was faster than the last setup's "official" dragy time. Even spinning, it did a .054 60-70. So it was still moving forward pretty good.

We are talking about trying all 3 transmissions. 2.97, 2.66, 2.29. Lots of work but will definitely be some good data.

That’s cooking. I have no doubt it’ll be getting down there given good gear changes and good air.
