Analyze my time slip

[Nottoofast50]

So the car was waaayyy slower than i hoped.... Here's how it broke down...

Mods are:

This was on crappy pepboys street tires and i was spinning all 1st really bad. Timing is at 12 degrees on 91 octane pump gas. Fuel pressure is stock. Any suggestions? I'm gonna get a converter and some sticky tires and an electric fan. Is my car not making good power? (was hoping for 260rwhp or more) or is it just the stock converter and crappy tires holding me back.

I am by know means an expert, but I will try to help. I'm sure you know your 60' time is killing you. With practice you should be able to knock some time off. The slicks will deffinetly help. Is this you're first time out with a new combo, or are you a novice like me? I don't know and no flaming is intended. What were you shooting for?

I would think that combo would be good for at least low 13's.

It's really hard to say, the MPH isn't bad but the ET's arn't too great. I don't think it's power that is the issue. Kind of tells me it's getting down the first couple hundred feet seems to be the problem. A better converter would probally solve that problem.

 

[Nottoofast50]

I was thinking the mph should be more like 103-104 range? I was hoping for 260rwhp at least which i dont think is too much to ask for my combo? The heads and intake are ported pretty good. Yes this is the first time with a new combo. I realize the 60' time is horrible.... my tractionloc is going out and i have crappy tires...I just thought the mph should be higher? Or is the traction problem bringing that down too? Should i bump the timing/fp? Also i'm wondering if a new cam would help out a lot.... the heads and intake are ported pretty good would i see much difference with a trickflow stage 1 or a diff cam vs the ecam? Car is a daily driver so i'd like it to be as streetable as possible.

 

[timewarped1972]

is your aod stock except for the cooler and shift kit?
i'm thinking of a similar combo for my car so keep posting your times and i'll be curious as to what converter you get.....
looks to me with traction and maybe some tuning you have what should be a 13.9 or 14 flat lil aod stang......as it is now. bet with a converter and traction you'll be able do even better. right where i'm lookin to go with mine as time and money allows....if your spinning alot in first it would be interesting to see what just tires would do...

 

[MustangPunk302]

Your pretty far from 260 to the wheels... Most basic H/C/I combo's like Edelbrocks and Holley's put those number to the wheels. Your actually pretty close, if not at, or beyond 260 at the flywheel though... With a good launch you could get better e.t.'s, if you didn't experience traction issuses then your AOD is holding you back at launch... You need a higher stall to get you outta the hole faster..

I have a simular combo and I run in the low 12's. I am running on BFG Drag Radials and I have a lot more suspension work done than you do. Here in lies the problem of your stang I think. The only suspension work you list as being completed is the lakewood drag shocks. This may help some but nothing of importance. You need to get a good set of Upper and Lower control arms for the rear, subframe connectors if you do not already have them, a lower A-FRAME brace like g-force. Also your stock AOD is not equiped to handle the power you are putting out, which I estimate is in the range of 260 to 275 RWHP. Others might disagree with me on this though. You should look into a aftermarket transmission like Art Carr. Also a torque convertor in the range of 3000 rpm stall should do wonders with your combo. I have known people to take over a 1/2 second off their times with a good torque convertor.

You should also look into having a aftermarket chip tuned and dynoed professionally for your car which should net you atleast 20 horsepower if not more.

Last but not least get a good set of drag radials and work on your launch...

Hope this helps

Step one is BFG Drag Radials

Step two is a looser converter.

The MPH is fine, and you have enough power already to have a much quicker et.

My 82 has run 13.40's at 100.

 

[90mustangGT]

Whoa, I was tired last night and didn't read the full mod list. Ported GT40P, Ecam, intake, TB, you should be much faster than that. Something isn't right, maby you should go to the dyno and see what's up.

Your launch is killing you. And your reaction time is real bad. 2.32 60' is pretty common for stock auto Mustangs. You need a performance torque converter (Precision Industries makes a real nice converter that has better torque multiplication than stock ) and a quality shift kit. Add sticky tires and you will be well on your way to better times.

I run 99 mph in my heavy convertible and have run several 13.78's with only 2.0X's and 2.12 60' times.

A good launch and reaction time should at least put you in the sub 13.75 range.

 

[Nottoofast50]

I plan on getting it to the dyno as soon as I can. I want to get a custom dyno chip burned but it's $500 that I can't justify spending on it. I think i'm just going to have it dynoed and try and have my friend tune it on the dyno with a/f ratio. Most aluminum head combos i've seen like holley and edelbrock usually put more in the 290-310rwhp range? I've even seen ppl with similar combos to mine running as high as that. I realize i'm very limited with my stock aod, converter and shift kit but just wanted to know if the motor was pulling good on the top end(making good power) or not. Guess i'll have to save up and get it dynoed to tell. Any things I can do before that to try and coax more power out of it? Should I bump the timing over 12 degrees? Raise fp over stock?

Your right the launch is killing me but shouldn't I have a higher mph with my mods?

Also when I ran the car with just 4:10s shift kit flows and pullies i ran consistent 14.4's with a 14.2 @ 97 best. I figured I should have more than a 3mph increase from all the mods?

You're too worried about your hp. Forget about that. Your 60ft's are killing you. If traction is your problem then slicks could really help. Every tenth in your 60ft is worth 2 tenths at the big end of the track. Even with a stock aod your 60ft's should be in the 1.8 range. Do the math...you could be running a low 13 second pass with a 1.8 60ft. Your MPH supports this assertion. Also, your timing is really hurting you. It should be between 14-18 degrees. 14 is really on the low side. With the AOD I'd run 16. I'm experiencing the same type of problems with my new combo. I feel you brother.

 

[Stump1000]

they are right, you need some drag radials or some decent tires. What elevation are you running at? Get some tires and try it again!

Well it's a daily driver and mostly driven on the street, honestly i dont care 2 much about traction bc i just want to be able to punch it on the freeway and take off. I know that the traction is a problem and plan on having some nittos and upper and lowers and a converter by the end of the year. My compression is raised from the gt40ps and i'm running pump gas so i didn't think i should bump the timing too much more but i will try and put it 14-16 next time i go to the track and see how it does. Thx for all the replies everyone and i will keep updating.

Elevation is near sea level(texas)

I have a similar combo, and I went a 13.5 at 105mph with a crappy 2.2 60' time. Keep workin on the launch, that's where I lose most of my time.
