Bolt-ons and not very happy with results....
Hey Forum,
Here's what I did: Roto-fab dry CAI - installed by me Soler Engineering TB - Installed by me Car ran fine no issues, somewhat better throttle response for a couple weeks Next, (all installed by local speed shop) Speed Engineering 1 7/8 long tubes Speed Engineering 3" catless mid-pipes Stainless Works NPP 3" in axle back Flex fuel kit Tune for E85 and 91 Dyno was 419HP and 448TQ (said it was because E85 was more like E50?? and a HOT day, >100 degrees) I was thinking should have been more like 440HP. Car is definitely quicker but is just too loud for my taste. I'm talking "piss off the neighbors" loud. I know I'm 53 but dang I'm not THAT old. I've been driving in Stealth mode and still too loud. I had the same set-up (almost) on my C5 Corvette and it wasn't nearly so loud, it did have catted mid pipes tho. I like a good deep growl but sheesh. I keep setting off others car alarms at work when I start it. If I go with 3" in/out cats will that tone it down (and make it legal) or should I do something else? FYI, I have factory NPP and had been driving with fuse 51 out and liked it but a little louder would have been fine with me. This is A LOT louder. Any advise will be appreciated. Yes, 1 spark plug boot is touching the header on each side so I have heat shields on the way. Link to start-up video: here

So you're saying you dyno'd 419hp after all parts were installed? If so, that doesn't sound right. Might be in the tune. As for the sound, should have done headers first to see how tolerable it is and go from there. I say switch back to the OEM exhaust and see if that does the trick.

tune sucks. and really since we are talking corrected HP, it is making more even less HP to the wheels. What is the uncorrected HP? Also all that no-cat SS 3" stuff does not add much HP... just saying. check for burned plug wire too.

I am gonna agree with Oldman, the tune is suspect.
Most of the HP gained from E85 is had by the time you hit E50. On a N/A engine from E50 to E85 you are only going to see 5-7 more rwhp. With similar mods as you during he heat of summer I made 424rwhp with catless headers, Roto-fab CAI, and a Pray ported TB/IM combo. When I added E85 to the car and retuned I got the gas tune to 431rwhp on 91 and 455rwhp on E85 that was at E60.

419 is at the wheels from the Dyno graph.

What was the dyno baseline?
What lambda was the car running post-tune for 419hp? And what about torque before/after? |

I figured that but I wanted to get rid of the AFM valves altogether. The SE LT's with the full length 3" mid pipes was only $650. Plus the LT's outlets are 3" and so are the SW NPP mufflers inlets.

I know, I wanted go with them first but they wouldn't touch the SE LT's and thier tune was much more expensive. I went with Extreme Motorsports cause they did my C5 Corvette years ago and did a great job.
