You know it's interesting to note that the Ferrari 60 foot time, at 1.9, is comparable to many high powered Cobras. Because of traction issues a 2.0 60 ft time is often "normal" for a Cobra.

Hmmmm,,, with equal 60 ft times, a Keith Craft built car and engine, I'm guessing Tommy is starting to get a little nervous. :) We got us a race shapeing up...

Ex - right you are. But now I've figured out how to use launch control and correct my rear tire pressure, so hopefully that number is going to come down a lot. That was literally a drive in and floor it 60' number. -Tom

Excaliber 02-21-2011 09:02 AM

I figure the launch control will limit power to avoid wheel spin which will result in an even longer 60 ft time,,, 2.1 maybe.

....evil laugh... :)

I would expect he would need clearance from blitz before letting the secrets out of the bag:D

If modern technology doesn't win, then something is wrong with the ferrari.

Not everyone, can finess a high powered stick shift, down a track, but unless you have a regular track car, there is no way for the average guy, to launch and get the consitency of shifts, to win race after race.

Anyone who has a few weeks seat time, with a modern supercar, that has all the bells and whistles, can make it go in a straight line.

tommygold 02-21-2011 10:09 AM

Ex - I'll take that bet. Stakes?

Excaliber 02-21-2011 10:35 AM

:JEKYLHYDE Eh eh, WHOA,,, betting with you is way out of my league.

If I can find some time to get to a track, I'll post the results. -Tom

You are not running wrinkle wall slicks, so be careful with the lower tire pressures.

A wrinkle wall slick works with a lower tire pressure as it allows a very large flat contact patch with the pavement. Your tires will not react the same. In fact it's possible that with lower pressures the tires will cup in the center and you will have less of a contact patch with the pavement.

And what's worse is that they can become very unstable at speed. If you are serious about this, start by lowering them a couple pounds and make a run. Repeat until you feel the times are lower and the car still feels safe.

Kirkham Vs Ferrari 458 Italia in ¼ scale
 
After purchasing a 458 Ferrari at the Naples Ferrari Club car show last weekend we had all we needed to set up our drag strip shoot out. Our Ferrari was stock but had to go up against a Kirkham with a SB 427 Chevy 800HP engine (God forbid). The Kirkham had no problem with traction and actually pulled the front tires a foot off the pavement and shot out a car length ahead of the Ferrari in it’s pursuit of the finish line. If we had used the Christmas tree the Kirkham would have had to spot the Ferrari as the Kirkham had no problem breaking into the 9 second bracket. I guess it also helped that the Ferrari pushed it so hard the Ferrari engine went up in smoke.:LOL::LOL::LOL:

Excellent post SB51! Tom you can check out your tire patch on a parking lot surface and make some adjustments there. Its easier because of the color contrast... oh and less expensive;).
Nice signature CobraDan:LOL: I still eat a donut or two on a Sunday morning. I think the new generation COP is into bagels. Just not the same anymore:(

Quality post... I'm still laughing, and guessing Tom is hoping that your post isn't prophetic :eek:

I'm working on a real Kirkham... but in the mean time where do I get me one of those scaled down ones?

Thanks,

TerrysSPF 02-21-2011 06:23 PM

Agree with the above replies CobraDan..................that was good stuff.

Hey Blitz, I would view Tommy's cancellation as a forfeit and take the money and run!:D

Mighty nice of you to change the date. However, I would negotiate and say a date change will cost him the ability for you to change your tires to something that isn't going to spin all the way down the track.
Honestly, it probably won't be much of a race without your ability to go to AVONS or drag radials.

As for everyone wanting to hear about Blitz's car from KC, what is there to know that we don't already? It's a Shelby alum block 510-511 with KC heads. Knowing if they are Stage II or Stage III heads would be nice, but either way, my guess is the engine has got to be putting out upper 600hp to lower-mid 700hp figures.
Hey Keith, what tires were you running when you were in Ohio? Looked like BB's to me, but which ones?

I can tell everyone this....................My friend Dave had an SPF (which is heavier) with a KC built Shelby alum 527 (similar to KC's engine in his personal car, and probably not too far off from Blitz's engine) and he ran low 10's on 15" Yokohama street tires (back when they were available). I think they were AVIDS. He would also get kicked off the track at Route66 in Chicago for not having a full cage. They get pretty upset when you make passes at 140mph in a car with no top.:eek:
This might be Blitz's problem if he gets a low ET or a high trap speed.:CRY:

twin turbo 02-21-2011 08:45 PM

Blitz said that a shop just dyno tested his car and it made 550 at the rear wheels. This is enough to put him in the 10's with decent traction (1.8 60 ft or better) and very good driving. If they prep the strip properly Blitz may get the traction he needs. Every 1/10 he can knock off his 60 ft will lower his ET at least double that. Will his half shafts and clutch hold up? Cheers.
Thomas

Excaliber 02-21-2011 09:25 PM

Thomas, I think the half shafts, rear end, etc. will be up to the task, even with drag race slicks (which he apparently does not have). Reports of half shaft breakage are actually pretty rare, all things considered. There are surprisingly robust.

Clutch could be a question mark, I don't know what he's running.

Do we have a confirmed revised date yet? John AKA, tin-man
