New PB for me yesterday - full weight 2.9 Whipple Cobra with Zex 50 shot

[truculentSVT]

So close, yet so far away! Went a 10.18@136. I was hoping to get that elusive 9, but it slipped away again! I believe if I would have had time to make another run I could have gotten it. The car is a TR 04' Cobra with a 2.9 Whipple/Kooks Long Tubes/O/R X with a Zex 50 wet shot. The car was full weight other than the Bogart RT wheels all the way around (even the spare tire was in the car). It has the stock longblock, stock T-56, stock IRS other than the BF IRS brace. The suspension is also stock other than the Eibach pro kit springs. I was on 28x10 Hoosier slicks.

This is a new personal best for E.T.. The car has MPH'd 139.5 last track outing.
Gotta keep diggin' an get that 9! :beer:

That is moving out!

Out of curiosity, what rpm were you dumping the clutch and were you using a WOT box?

Thanks,
Todd

Get those 60's down and you'll get there with ease!

 

[truculentSVT]

Hard to explain.. Didn't really dump it, kinda ride it some, but I would say it was around 4200 or so.. Don't know what I shifted at, I do not have a shift light. If wot box you mean for the nitrous - I use a Zex traction control window switch and the Zex box taps the TPS. And if you mean WOT shift box- no I do not have one..

Whats the best 60's guys are getting with the IRS/6 speeds?

I've gone 1.51 with a stock IRS on a 26x10 et drag

 

[Wicked46]

A guy in town is going 1.49's with stock IRS and ET drags... Hasn't broke yet haha. I'm going 1.42's to 1.45's on a SRA

Very nice ET for the mph! How much boost are you running? I would think that you would've picked up 32-33mph on the big end.

 

[timspony]

Nice run for sure with a full weight IRS car!!

I've seen a 1.57 with the exact same suspension set-up!!...I think you're doing very well!! ...You'll be in the 9's before long! :beer:

 

[svt4me38]

That is flying!!! Congrats, what's your race weight?

Nice runs but I gotta ask you really don't know where you shifted at? If you test to find the perfect shift points you could easily go faster!!!!

Nah, I don't really look at the tach, I just shift by ear & feel. I don't have a shift light.

The car has mph'd 139.5 mph a few times.. Boost is like 19.5 lbs I believe, right at 20

I'm not sure, the car has never been on a set of scales lol .. I'd say 38 something if I were guessing without me in it. I weigh 215 lbs..

Very impressive!!
I was at BG in Oct chasing the elusive 9.
Best run was a 10.05!!!
Could probably have farted the extra .06 to get the 9!!! :fart:
Maybe next time.....

My best 60' time has been 1.52 Brandon. Stock axles with a Billetflow IRS brace & all IRS bushings replaced with Delrin or aluminum.

Congrats on the new best time!

I've was running consistent 1.51-1.54 60's last year at our local 330' foot track. But I believe it has better track prep that Clay City. I say was as before I broke a halfshaft. I broke the one and only half shaft i've broke at the '330 track and it was due to dead hooking. The car just broke and never moved. After that I lost my confidence on the launch and just now have gotten back close to how I was launching before.

 

[speeddemon2000]

How much boost and what fuel?

 

[truculentSVT]

How much boost and what fuel?

19.5- right at 20.. The fuel of choice is Shell URT Advanced.. the best fuel out.

Is that on a 17" Hoosier 28x10 slick?
