Heh...if someone can host a rather large file for me...I'll let the sheet speak for itself. Look at the mods below and tell me what I'm prolly putting down....then look at the sheet and tell me someone f'd up keeping in mind some dragging and roadracing and the motor is still in one piece.

@12 psi, I'm uneducatedly guessing somewhere in the 310rwhp range?

I'll host the sheet for you, mx6gt2@hotmail.com

Thanks!

Ok. So I brought it over on Sat originally to get this done. They were having issues with getting a clean tach signal. We originally tried on the #2 rotors wires. It was recommended that we go with the #1 trailing (if I can't remember. The top left guy...I can't for the life of me remember the rotation).

Anyway, it was extremely hot, so we decided to do it Tuesday morn. I dropped it off Mon and they proceeded to do their thing. I wasn't there as I couldn't be. I left EXPLICIT instructions to ensure that it was fully warmed up. They used a wideband from whatever was in house. I don't know anything other than that. At least, I told them to.

This was the only pass. He didn't wind all the way as the A/F was a little high. That part confused the hell outta me as if that's accurate, I would have blown my motor months ago. Mods are as you see them. I think I'm on the stock pump and injectors. Even so, and this has been reenforced, there's no way in hell I can be running that A/F. So, thoughts, suggestions, ideas are greatly accepted. Anyway, there you have it.

Utterly disappointed.....

All fixed and smaller now.

I'll be the first to chime in with the "Wow that sucks, only 195 hp, those guys must be idiots. Why'd he let off early (AF ratio)" comment.

Time for a Power FC. With those A/F ratios Im suprised your car still runs.

Rotaryshack did my firstgen with their turbo set up and it came to close to 225rwhp and 217 torque. He mentioned it was 10lbs of boost and 91 octane gas. HP was at about 6500 rpm and torque..i forgot. He even weight my car at 2240lbs at a certified scale. Wonder what that would turn in a 1/4 mile?

I would of at least expect 270-290 rwhp for yours.

911GT2

It's on the way, (see his sig, mine too, oddly enough.)

See above for story. Editing took longer than I thought.

The butt dyno whole heartedly disagrees with this. Come for a ride and you'll know that this is WAY off. How can I make LESS than stock??!?!!??!

if the afr is accurate it is the answer to your lack of power. you can't make power without fuel. the afr line looks linear w rpm so it is probably not a dirty filter. could be your high voltage fuel pump circuit isn't working. more likely an ecu problem. power fc w/b a good investment.

Thanks...but I can tell you that I AM making the power. 195 would not feel like it does in mine. 1 1/2 weeks and the pfc is going in...

I think something is wrong over there, thats the second car I heard they(StreetStuff) said this about, the other was a SC S2000 reading like19.0 said they could only do a half run or something.

Scrapiron7

I hope nothing is wrong there! I am scheduled for 2 hours of dyno/wideband time next Thursday

Railgun

Ok....some of you may have read that little blurb up near the top of this thread about a reference to a-spec (before i deleted it). Lemme clarify what I had meant.

It may have been misconstrued(sp) that I was disapointed at them. That's wrong.

As some of you have probably seen, there was that post about what's his face blasting them about BS. If you noticed I defended a-spec. This dyno thing in no way changes that opinion. This has nothing to do with their quality of work and service that I've experienced...which is top notch. I know my car runs great! I KNOW it has a HELL of a lot more power than what the dyno thinks. Everything a-spec has done has only IMPROVED the ride and my level of enjoyment with it.

I was referring to the results of the dyno and the fact that they were as odd as they were being the root of my disappointment. I was questioning the method used during the test and find it hard to believe that it is accurate...again, if it were, I should be on my 3rd motor. Sorry Sean, Steve and Steve if it came off that way as it wasn't meant to. I still love you guys.... THAT WAS A JOKE!!!!!!

Seriously...this weekend I'll figure it out. Unfortunately I only have a modified stock ECU, so I have no idea what my injectors are doing. That will change very soon.

So...sorry a-spec....everything's cool...

Back to more suggestions.....

Looks like bad dyno testing runs in the family. That sucks, man. ..at least you're still on your 1st motor though.

kyle@insight

He wont be on his first motor for long wiht an A/F like that. I'd be scared to even take the car into boost. That's rediculous

ZeroRXSeven

I dunno man, i've been in his 7 plenty 'o times, there's no way he's losing power. There has to be a mistake somewhere.

Railgun

Yeah. But tell me. With that A/F, do you really think that I'd still be driving it? Meaning since I've had it I've run the **** out of it. Now, the motor only has...maybe 15k on it right now. Even so, with some dragging, track running and general street mayhem would it be safe to assume that my motor now should have died a while ago? I'm still hitting 19 vac. Idles as smooth as a baby's ***. Spools up quick and runs sweet all the way up to redline. I'm telling you, that A/F is just that. All Fu*ked!

Either that, or whoever built that motor built the **** out of it! Now I NEED to find out who did it.

The driver might have let off the throttle while the RPMS were increasing. The boost may have lowered and the A/F ratio would have up. Nobody really knows if the car is running lean at WOT.

Do you guys really think that the wideband is accurate at the tailpipe? I really don't think so.

well 1 thing I figured out after 30 plus pulls on the dyno. If you drive up on the dyno after the car has sat while you were watching other cars, the first time you get on the boost, the stock ecu and my M2 stage 3 wouldn't let me make full boost since the ecu knows its not good to make full boost on a cold engine. My car made 218 to 220 but the next pull shot up to the 300 range. After about 3 attempts at getting a good clean first pull after letting the car cool off completely, and the same thing happening every time, I started doing a half pull in 3rd gear to make 7 or 8 psi and let off, then immediately do the 4th gear run. Works everytime.

Was your car cold or not up to temp when you did the pull? What boost did it make, do they remember?

Maybe they didn't hook up the car correctly, I did 301 with close to the same mods you have.
