dyno results MP VS HFC
I did a dyno a few months ago and at 12 psi I had 266 to the wheels. the graph is below. My mods then were the same as now except I had a HFC, stock injectors and FP, instead of a MP, 1200 CC's and FP. The injectors and FP should have had no bearing since I ran a 12 psi.
it will not let me reattach, so here is the original

Next...here is my new one....

heres the boost and tq...
Please note, my base run on this was 298, he did some tuning to get it 315. we ran 11 runs so its consistent.
anyone know how to figure out torque? I think its about 265?

How often on the street are you above 4K rpm? Unless im racing I shift around 4K and its quiet.
the smell is very tolerable. only at idle with the windows down and its not that bad.

I rode in ZeroBanger's car the other day and I can say that it is tolerably loud. It is definitely louder than my car with just a downpipe and RB cat-back, but it is not as bad as I've heard IN THE CAR. David said his car was deafening on the dyno OUTSIDE THE CAR.
BTW, I need a Power FC. David's car ran so smooth with a tuned PFC, I'm jealous.

BTW...
My first dyno graph (266 hp) was done in 4th gear.
My new dyno (315) was 3rd. I guess 3rd was better for tuning purposes.
oh yea and I remember the sound with my HFC when I dynoed and it was fairly loud. With my MP I had on earphones and walked 100 yards away to the shop next door and it was So freaking loud. Of course you are in a building so it echos, but I was in a building before with my HFC, too.
Yea Rynberg and me had an adventure that involved my car, 85 MPH in a 30 MPH zone and a cop in a SS Camaro Cop Car going the other direction. use your imagination, LOL.

BTW..
I need to clear something up. My car was originally Tuned by Ricks Rotary performance in pleasanton (rx7fasion). Rick does not have a dyno but he has some specialized base maps . He did a very good job on the a/f. Shiv said it was near perfect (10.5 to 11.1) and although he could shave a little fuel off, he said its very safe and in a really good range. Shiv actually added a little fuel during transition cause of my spikes.
shivs tuning was solely timing and not with fuel, except at transition.

I thought that was an issue before, but I dont' think so now. My guess is a few HP on top end, maybe 2 -3. someday I may get a regular dp and see the difference.

midpipe with Borla XR-1
If you are worried about noise with a midpipe then just get the Borla XR-1 welded in. Much quiter than the resonated midpipe I had. The 16" sportsman XR-1 fits right where the cat went. Looks as if it was made to go there.

Guess what? the power FC does NOT show when you over boost. it showed like .88 when I had .85 as my boost, but it spiked to 15. Same when I dynoed.
I only ran a 13.48 @ 105.6 with a 2.17 60'. Something is wrong. everytime I get more power I run slower. I was able to run 13.0 @ 108 with a 2.03 60' with much less boost before my midpipe.
