Mph in the quarter....

[IZZy]

The best mph I got was a 115.78, does that seem kinda low for a pullied cobra? the other thing I noticed is after that pass the mph just kept gettin worse, Im thinking the blower was gettin hot and the coumputer started pulling timing...
12.36 @112.16 60ft 1.94
12.15 @115.29 60ft 1.91
12.12 @115.78 60ft 1.82
12.15 @112.53 60ft 1.81
12.22 @110.58 60ft 1.76
The 60's kept gettin better but not the speeds, what mph have you guys run when you were pullied? I figured with the cool air today I shouldve seen 118's, what do you guys think?

shift points, iat's, coolant temp and driving skill have alot to do with mph and et... what did ur datalogs say?

 

[IZZy]

what did ur datalogs say?

I was shifting very near redline,
I got no idea how to look that up Bob, do you just hook it up to a laptop?
what can I do to help the IAT's?

kinda hard to tell ya anything with not having any information..

but, i can guarantee that its 90% driver... ive seen a 450rwhp cobra go 110 and one go 123... only difference was the driver.. have doodad drive your car and I BET it goes 120+

as far as helping IAT's, create a jumper wire like i did on the dyno and get a fan to run in front of the heat exchanger while in the pits.

have doodad drive my car... that sounds dangerous:lmao: but anyway, the other thing I noticed is that on the 2-3 shift it kinda hicups for a second when I mash the throttle, ever heard of an issue like that? I really need to get a laptop so I can datalog this stuff.

That's a common problem. Im sure bob will chime in.

 

[Bob_Kurgan]

as chris stated, thats a common problem... there are 2 ways to get rid of it.. #1 removing/deleting the PPRV valve... #2 the easier and cheaper of the 2 is DRIVER MOD LOL... you can ask chris to describe that one !!

 

[Bob_Kurgan]

btw, buy a Raptor shift light... factory tachs are known to be "not so accurate"... if you want to be consistent and fast, repeatable shift points are a must!

OK, Im assuming you have to drop the tank for this then... or Chris... how do you get that driver mod...

And to think I was going to come to you to pull some more timing :knk:


:joke:

I do not have teh drive mod.



Prepair for your thread to turn into shit unless the nutswingers lay off

 

[doodad]

hmmm.. if that is hesistation then yeah as Bob said PPRV delete. how are your plugs? I had the same problem and Bob gapped my plugs to 28-30 and never had it again till like a month before i sold the car but then it was the FRPS.

good luck Israel!

Damn, I thought it was just a joke... anyhow do you have to drop the tank for the PPR delete?

 

[IZZy]

how are your plugs?

I just put fresh TR6's at .32 before I got the car tuned.

 

[Mr. Unknown]

 

[IZZy]

^^^Cool, thanks man.

 

[Bigturbonotch]

chris let me borrow your driver mod on the 3 to 4 shift

 

[IZZy]

chris let me borrow your driver mod on the 3 to 4 shift

Oh here we go...

 

[Mr. Unknown]

chris let me borrow your driver mod on the 3 to 4 shift

As long as you promise not to break a shift fork

 

[Bob_Kurgan]

maybe im missing something, but i was serious.. i always thought the driver mod was when the driver doesnt lift completely off the throttle and speed shifted... am i missing something?

Sorry Israel, never thought to mention, you should have been shifting at 6k, that would have made a HUGE difference and the hesitation goes away if you stay in the throttle power shifting.

When you say "stay in the throttle" how much so? like Full throttle the whole time or do you let off a littel, myabe have the gas 1/2 way or 3/4 of the way to the floor? cause i granny shift, i thought power shifting would tremndously seped up the deterioration of your driveline/trasmission.

If you get your shifter/trans problems figured out you could practice powershifting. Right now it's not really an option, but ideally your right foot stays planted during the whole run.

Thanks for the info man, with all that I learned today Im confident I can bust out a 11 sec run next time.

I've done both... lately the 2nd due to my tranny taking a dump, since power shifting can lead to broken keys. The sliders sometimes wear down and possible shift forks. If you want to go faster, I guess this is the price... :-o Let me see if I can find one of my videos...
