Superman09 hits the track, first time with FI. Need input....
Superman09 hits the track, first time with FI. Need input.... Well today i crossed the border and went over to Grand Bend for test n tune. I made 4 passes, only 1 lane was open so it took forever to get runs in. I find my car runs stronger and makes a little more boost once the turbos get hot and i could not hot lap the car tonight due to the way they set it up... bikes go, then street tires, slicks, etc. Heres the deal, 5 psi, spraying meth up top to cool IATs even more plus FMIC which isnt in the greatest spot but oh well. At the 5 psi my car made 420/413 on a mustang dyno. I made 4 passes, here are the results...
Run #1
60-2.100
330- 5.563
1/8- 8.291
mph- 90.12
990- 10.656
1/4- 12.647
mph-110.66
Run #2
60- 2.030
330- 5.474
1/8- 8.215
mph- 89.65
990- 10.601
1/4- 12.617
mph- 109.24
Run #3
60- 1.965
330- 5.404
1/8- 8.161
mph- 89.01
990- 10.570
1/4- 12.607
mph- 108.03
Run #4 (cutouts open)
60- 2.049
330- 5.478
1/8- 8.218
mph- 89.59
990- 10.607
1/4- 12.628
mph- 109.10
The car runs .9 seconds faster in the 1/4 than it did last year, but only like 4 mph faster.... It seems like something is not right with the car whether its off the line or in the top end i'm not sure. My trans could be slipping, i could be pulling timing (no way to tell), or i could be spot on for the power i'm making. Would like some input and if you guys can tell anything from my times, give me some info that could help me out. Car is a stock stall A4 BTW and was on 18" BFG DRs and was hooking up. Thanks! Yes i know the boost is low at only 5, i will be upping it soon, just wanted a feel for the car and to find where it stood, so please comment on how you think its doing for what it has, any issues you can think of, etc. Thanks!

Hmmm, I would say that you better start looking for somewhere to build your tranny and also you may want to go with a converter...
Honestly not too bad considering on an 18" tire, stock tranny, stock stall, stock etc... You'll get it down for sure...

yea, i know it has a ton of room to grow, im just wondering if these baseline times seem okay, or if there is something sticking out that might show for example my car dying on the big end... i honestly thought it would trap more than this...

Is your tach flashing really fast?? It looks as if it's pushing through the converter or something... I would also say to try to get your 60's down... In order to do that you're going to have to probably get a taller tire, different converter, make sure there isn't any mechanical issues: i.e. trans slipping, converter failure, etc... I think even though your 60's aren't that great you SHOULD trap a higher speed, run a better 8th, and ultimately run a better 1/4... It would be great if you had some tuning software so that you can log and see what's actually going on behind the scenes... Goodluck man

You've got some kind of problem. Maybe it's the trans, none of us can really tell you that, but my car ran the same times & mph with headers and a converter on street tires.

something isn't right unless your car weighs a crapload.
when I had my powerdyne at 5.5psi it was making a touch over 400rwhp and I trapped 116mph. I still only ran in the 13's
but the mph was decent.
110 seems quite low.

you also have to look at your 60's which at 1.9-2.0 is kinda shitty for e.t. but considering your on 18's and a stock converter you cant expect much better. you still may have some other issues because that mph does seem a bit low. Hope ya get her figured out...goodluck.

M/T drag radials, at least 2600 converter + at least 8 lbs should get you in the 11 range. FWIW my first pass with the Vortech kit was 12.95@108 so it doesn't seem out of line to me. I doubt your pushing through the converter (not enough power).
I wonder what is making my MPH lower though, i wonder if its a slipping trans, maybe pulling some timing, not sure. Based on all my times, 1/8 to 1/4 and such, do they all seem to add up or does the car seem to be losing power somewhere? Thanks for the input. The car will definitely have more boost and a stall coming soon, just wanted to see where i'm at first.

i agree the 110 MPH is really slow for a turbo car even if only with 5 psi
my brother has a 1999 6 speed with long tube headers, lid, tune, and loudmouth and he ran 12.66 at 113 mph at Rockingham
I have a Friend with a 2000 6 speed that dynoed 420 RWHP and it ran 12.5 at 117 MPH, it has an older set of cnc ported 5.3 heads with a small cam
my car ran 12.9 at 110 with just a lid but it is a 2002
on a other wise stock car I with only 7 pounds of boost I ran 11.90 at 122 mph on my best pass, but my car is a 6 speeed
the car had nothing done but the PTS single turbo kit on it and of course a tune

Yea, 6 speeds trap and run totally different than an auto though. Cant really compare there. However it does seem low, i am making rouhgly 120 more hp at the tires than last year and a lot more torque much earlier but its only netting me 2 mph i nthe 8th and 4 in the 1/4..... Something doesnt add up.

One thing i'm thinking as well is.... Maybe the car was pulling timing.. I was thinking about it and know if the IATs get so hot, the computer pulls timing. With my set up, the FMIC isnt in the best spot, but not bad and it does have meth. However, the kicker is that the IAT sensor is right after the FMIC so it would be reading the air coming out there correct? and if thats too hot, it will be pulling timing. The meth sprays into the TB so even thought the IATs could read high, maybe my intake temps were fine due to the meth? Could be something...

i think it might have been pulling timing now. Considering my ET dropped as it should from last year, the MPH really doesnt match it for those bad 60's. with 2.0's and 110, my ET should probably only be around 13.0 right? I thin kthe car picks up hard at the bottom, then maybe its pulling timing up top which is killing my MPH, but my et still drops more due to it picking it up much more earlier? Sound logical or not right? LMK what you guys think. Thanks!

you have anyway to log some runs?? you'll wanna check to see if your getting any knock which would pull your timing. Your car should be cookin up top with those Turbos even at 5.5psi...i would expect to see about 115-117 atleast.
