First Numbers For The Boostang!

[84Ttop]

+1.

I can't think of any reason a tuner would want the power over speed instead of power vs. rpm. Every change in the tune you'd ever make, you do it at a certain rpm. So unless you want to back-convert to the rpm knowing your gearing numbers, the speed is pretty much useless as far as I'm concerned.

The only time that we really use the mph based graph is in some of the higher horse power stuff that climbs through the rpms very quickly. The mph based graph slows the ramp down and makes it a lot more pleasant to look at vs a vertical line
This is a dyno graph from some testing beginning of last year with my car and you can see how much more difficult it is to read vs the mph based graph posted above

(never mind how the ramp dies at the top of the rpm band. we were testing blower efficiency and we were spinning a V24 X trim well beyond its limitations hence the dramatic loss in hp up top)

Not sure on the brand (since my builder provided it). I believe its just a 107" (or something close to that) off-the-shelf O'Reilly's belt

Oh, and other great news.....aside from the crazy belt slip, its misfiring. I almost feel like giving up lol. The thing still fkn hauls though!

If you're having issues man I would not be getting into any boost at all and I would even not want to drive it till it gets figured out, who knows what kind of damage you could be doing with it's issues. I would highly consider trailoring the car to SA/DFW to get a real shop with in house mustang tuners who know their stuff.

I really appreciate the concern TXred. I honestly isn't as bad as it sounds. I trust my builder 100%, he's built so many mod motors Mustangs that he could probably build one blind-folded. He is a walking-dictionary of Mustang knowledge. I didn't know much about the tuner, but I've been talking to him multiple times a day on the issues. He's tuned more Mustangs than he can remember, including some 9 and 10 second GT500's. The car really does run smooth as hell. There doesn't seem to be any misfires of any sort. He assures me that the graph is a direct result of a mechanical issue, not a tune issue. He told me that the AFR's are "perfect".

He's so confident that because of al this controversy on FB and all these forums, he has given me a 1 year warrantee on anything tune-related. I've driven the car, it runs smooth as stock and absolutely rockets on WOT without any symptoms. In-car wideband looks awesome too (11.1 max on WOT).

Going to the track tomorrow night. We'll see what it does.

id take it to a different shop as well for another opinion. The guy who tuned my mustang has tuned over 7000 mustangs in the past 20 years lol...some 8 sec street cars even in the Toronto area

Oh I am. I'm good friends with a group of turbo Fox's who call themselves the "Turbo Mafia". The slowest one of them runs lows 10's here in a 6500ft DA. They don't have a shop, do all the work themselves, and tune their own cars. We're all going to the track net Fri and they're going to datalog the car.

*UPDATE*

I pulled the 3.00 of and sent it to Carbinite to be coated. I stuck on a spare 3.25 and.....

HOLY ! Im seeing 15psi on the street. It's still slipping just a hair but the car feels like it's gained 100rwhp. It keeps pulling HARD until I run out of gear. My tuner also drove it post pulley swap and says its an easy 80rwhp+ gain from his experience.

Now here comes the problem. On one of our WOT test passes last night, a pre-IC pipe blew off. Apparently blowing off a pipe just after the blower completely wrecks . It completely took out the coolant reservoir. Broke both upper supports and bent the hell out of the support. It also destroyed my drivers-side fog light. Completely redoing the hot side tubing with 2 3.25" pipes and 3 couplers. Going to roll a HUGE lip on each of the ends of the tubing and run a quad T-bolt on each coupler. We're guessing that the current IC is just way to restrictive and building insane pressure pre-IC

That sucks about your luck with the piping. Its good to hear that you are picking up some nice power as the belt slip is starting to diminish.

Is there a way to weld some of the tubing together to limit some of the joints and potential places it can blow apart later? I know there would be added cost doing things this way but the piece of mind is priceless. I typically weld as much as I can and leave the couplers for items like the blower itself and the intercooler. Just a thought. Good luck getting it back together!
