Guess what I found out after reading some stuff on the M370?!?! This will certainly explain the problems we had on our dyno last fall!!!

2 weeks ago, i got back on the dyno since then adding a Stillen Gen 3 intake and heavier 20" rims in 20 degrees warmer in temperature. Baseline was 287 hp with areas under curve losing up to 20 hp. Uprev was then able to recover 4 hp resulting in peak power of just under 292 hp.
Do you guys think the manifold does not play nicely with full bolt ons and tune?
The reason you lost power on the last dyno was the larger wheels. I've dyno tested the effect of wheel size Vs HP and it can easily swing +7 to -15 HP. +7 to light weight race rims with R compound tires Vs stock Vs -15 HP for large heavy rims.
-----------
This part here is a good trade. Do you have the dynos?

Lookin good Dan! Mine is almost complete. I will hopefully finish it up Wednesday, I was confused where I tube went and looked over the pic again and found it :-) But I won't have a chance to start it for quite awhile. I'm pretty sure I couldn't start it and JUST let it sit there.....omfg

Also wanted to throw this out there for our future Dynos!
The engine that makes 300 pound-feet of torque at 4,000 RPM produces [(300 x 4,000) / 5,252] 228 horsepower at 4,000 RPM. But where does the number 5,252 come from?
To get from pound-feet of torque to horsepower, you need to go through a few conversions. The number 5,252 is the result of lumping several different conversion factors together into one number.

I was pretty tired after last night. I was thinking it was hp to tq and would tell us where our torque is when the dyno graph doesn't pull it up properly 
But yea I will. I can see tho now, after reading about the wheels, why our power would be lower Lance than what we had anticipated given our 20s on there compared to the stock wheels

Throw that bish on!! How are you liking it with the recent mods you guys threw on? That mrev makes a big difference and in my experience it actually made my setup a bit quieter which was really nice! Not to mention the extra torque where you want it most
The two bolts I had to drill out took up like 90% of the time it took to do the install. Keep in mind I was doing this in 10 degree weather....
Lets just say I'm not installing anymore mods for a while haha
I will get a sound clip asap.
Haha, he can't handle it now that my car is fairly loud
