No. My car made 575whp and 575wtq on a very conservative mustang Dyno. The guy that owns the Dyno said his basically stock Hellcat made 520whp on his Dyno. Since being at the Dyno I built the exhaust dumps on recommendation from RC dash. He said his car made 200 more whp from removing the muffler. I'm not saying mine did as well but I did pick up mph from the dumps but the clutch broke on the first pass with them on so I don't know what the realistic hp gain is from them and I really don't want to spend more money on Dyno time just to get a number. I'd rather let et and mph show me the gains.
Ya another problem I have to fight locally is the track is always garbage they might spray one round of prep on a test n tune night. Then all the cars with street tires tear the track up for the rest of us. I'd really like to get the car to a nicely prepped track and see what it'll really do with good track conditions. Only problem with that is there is a lack of safety equipment on my car haha. Stock seat belts no cage no drive shaft loop ect. But if I could bust off the best pass of my life and then get kicked off I'm fine with that haha.
Yes I pulled both air filters on the very last pass I burned the clutch up on. But I've ported every stock piece of the intake manifold with a flapper wheel on my die grinder and gasket matched the port sizes on the runners and lower plenum. I also have a Crawford upper plenum and sikky thermoeliminator gaskets on heads and lower plenum. I'm going to work with what I have there. The next go around of upgrades will consist of 2000cc injectors and probably switch the car over to ignite red ethanol and turn it up!
I think he said he took off the air filter, so no restriction there. If not, then he should take it off.

Arent you still running the greddy intake (filter to turbo)? It's the inefficient greddy filter to turbo inlet pipe ... mine neck down to 2.09" ID diameter?
Welded myself at work not bad for not being behind a tig in 5 years.
Yep I built some dumps. That's also the same day the clutch started slipping but I gained 3mph from the previous passes. I'm gonna get the clutch rebuilt and go try to break stuff again and see what it does.
I like it! Since I started this thread I've made a lot of progress. Still haven't gotten a great 60ft but 1.69 on stock suspension and lowering springs isn't bad. I found some errors in the tune and got the antilag all worked out. Turning the antilag off at 1mph did the trick. I also backed timing from -25 to -10°. It has worked flawless and the car doesn't bog anymore and makes plenty of boost with the upgraded turbos (spent the coin in the FP blacks). Throughout the season I kept throwing boost at it to get my et mph up and wasn't having success. I went up to 25#'s from 18 and didn't gain any mph. Was kinda stumped cause those turbos really aren't even in their efficiency range yet. I had someone remote in and tune the car on the Dyno the last time and I decided to go through the timing map and found that the car only had 6° of timing at most and less in places. So I just added 50% in boost turned the boost controller off and it gained 4mph over previous best. I think I got it up to 12° which is still somewhat conservative on VP110 and got boost to 22#'s. The car went 7.02 @ 107 with a 1.78 60ft best to date.
This year I went ahead and ordered the IDS drag coilovers. Installed SPL camber, toe, and traction arms, solid diff bushings, subframe inserts, monoball knuckle bushings, koni single adjustable shocks up front and some 17" skinnies up front with a bias ply. If it doesn't 1.5 60ft with at least a 6.7 et I'll probably burn it lol. Also adding a 50 shot to bring IAT's down on hot days and for those money races. With these upgrades it should realistically work extremely well but we'll see once the snow decides to go away.
