Continuation of Thread: Drag race - Kirkham 65 side-oiler vs Ferrari 458 Italia

[RodKnock]

It's a REAL ORIGINAL Kirkham Cobra. And it just beat a new Ferrari in a race.

We haven't heard from Evan since the judge ruled EVERY Cobra manufactured after the CSX3000's as replicas.

Computerworks, you took the words right out of my mouth about Gus Zuiderma's (HARR Ford) Cobra

Thanks Tommy and Blitz for a spirited event that warmed my winter and now has me drooling to get my cobra out this weekend.

It was all about Blitz getting the traction and controlling the launch and hitting those shifts (even if he did granny shift) he didn't break anything!! (great job).

Guys,

I looked forward to coming home every night after work and catching up on the latest news. it's been an awesome ride over the last 6 weeks or so. thanks to Tommy & Blitz for sharing with us all and i can't wait for the next installment.

....they are grooved Goodyear slicks.

I saw that, and several other posts from Blitz about tires. Heck I TALKED to Blitz on the phone (drag race consultant ) and STILL can't figure out what tires he's running!!!! Sorry I couldn't make it down there Dan, man I missed a really good show.

They do not appear to be on Kraus' site. The Cobra slicks on the Kraus site are yellow letter road racing slicks with a very stiff side wall. I run them on my car, they can be (mine are) hand grooved "for street use". They are NOT drag racing slicks and do NOT have great traction when they are cold, and man it takes a long time to warm them up.

Blitz (Dan) has white letter grooved "slicks". Factory grooved? Hand grooved? Road racing? Drag racing? What the heck ARE those tires?

Here's the bottom line:
A COBRA just kicked Ferrari's ass,,,, again.
After that, the only thing we have left is "excuses". I hear those a lot at the drag strip. But I missed third! Your running an illegal modified motor! My tires were cold. I couldn't get the carb dialed in in time. It's not a factory setup. Well if you had an old,,, blah blah blah...

The tires I ran were Goodyear blue streak factory grooved roadcourse slicks. There really arnt many Goodyear vintage tires, I'm not sure why you are having a hard time finding them. I didn't get Em from roger Kraus, the Goodyear tire place had yellow letter drag slicks, blue streak roadcourse grooved slicks, and the billboards. I bought these tires about a year and a half ago when I ran the road course in parump. I'll send pics if you would like a close up, they arnt anything special, but are better than billboards for stability at speed and are slightly softer I think. The biggest problem w Em is it takes a long time to get them up to temperature, this wasn't an issue when I ran in Vegas as it was hot and sunny, the track was well prepped, and nice and warm.

So - you gonna gimme a chance to get you back for breakfast at cars & coffee tomorrow?

[Excaliber]

Ah,,, there it is, they are G7's (I'm pretty sure?).

Yup, factory treaded, but just barely. They really are a "race" tire cleverly disquised as a street tire. Their almost as good as the full blown road race yellow letter slicks. An excellent choice for a high horse power street driven Cobra. For some reason they are not a very common choice among Cobra owners, which I think has led to some confusion. They are a BIG tire and present clearance issues on some Cobra's.

They are BIGGER than the yellow letter slicks which just barely clear on my car! I don't think I could run G7's. Kirkhams have great clearance, early ERA's, not so much.

Well done Dan. You know when you posted some of your early 1/4 mile ET's in the 13 range, I thought you were going down in flames man. It was a dark moment and certainly added to the suspense.

Excaliber, I have sent you a PM.

You have the wrong tire again, they easily fit in the wheel well, however they arn't disguised as a street tire at all, they say right on the tire not legal for highway use. They are an inch smaller than the billboards height wise, I just googled it and this is a picture http://cgi.ebay.com/ebaymotors/Goody...esQQxZ31QQyZ10

[OZCOBRA]

Kudos Dan.....For me you were always going to win at least one if in not more!!!
.....as you posted re; the 2nd bet I reckon you played it with some real smarts!!!.... would have been real easy for the untrained gambler to get caught up in the emotion of such a prize to be had !!!....still a good bluff !!!

It was also great to see both of you get down the 1/4 safe and fast.

Finally you have both contributed to an awesome thread here and thanks for persisting with all the early negativity and rewarding those that embraced your postings and really look forward seeing the future events you guys host!!!

The Goodyear Billboards have the same/similar verbiage on them, Blitz.

Dan - Ernie and others are having a hard time figuring out what you ran because no one else really refers to those tires as "grooved slicks". They are G7 vintage treaded road race tires, which don't use the most modern compounds and construction attributes - it's quite surprising you did as well as you did in the drag race with them. Look at the sizes on the sidewall, are they marked 6.00x15 front and 8.00x15 rear?

Before you go on a road course again I strongly recommend you put a set of real grooved slicks on, listed on Roger Kraus' web site as "C-2" under "Cobra tires": http://rogerkrausracing.com/pages/pricing.html Those who have run these on road courses say they are night and day better than the tires you currently have, not only in grip (seconds a lap faster) but general balance/feel. I like the "Historic Old" tread pattern over the standard pattern Kraus uses (his choice is less time consuming for him): but it's just a personal aesthetic preference. Note that even these slicks are not as good as the most modern 18"-20" rim race slicks.

[Excaliber]

Dan, I suspect they are indeed a "G7", blue streak, old school type tire. They offer about the best you can get in traction. It was miss leading for me to say they are "cleverly disguised as a street tire", the same could be said about the Goodyear Bill Boards, which are also treaded, but in fact are a "race only tire".

I had my yellow letter slicks hand grooved so they would have the APPEARANCE (cleverly disquised) of a "street tire", all though, if you read the side wall, yup, they are "race only".

The G7 tread pattern is factory, it could be a bit miss leading to call them "grooved". Some modern race tires (usually DOT approved for the street) are really grooved. In that they have maybe two or more literal grooves for "tread" rather than a full face tread pattern.

Kirkhams have a LOT of clearance. The G7's are really WIDE, not so much tall. Avon's are really TALL, not so much wide. Not all Cobras can run Avon's either because of clearance issues.

Where's Tommy?

He brought us this thread and all the fun that went with it.

I heard he was counting out the payout in 1's, 5's, and 10's

[Buzz]

I had a real fun time this morning at Cars & Coffee with Larry, Mr007 and the rest of the Vegas Cobra guys. I'll start a new thread with pics as soon as I get them downloaded. Great bunch of guys and some real nice cars.

[Excaliber]

Perhaps he is graciously letting Dan bask in the moment of victory and it is a bit premature for him to interject a comment at this time.

......,,,,,,.......,,,,,,,

OK, times up. Where's Tommy?

[vector1]

good read! only thing better would be to put everybody who posted in the same room (including the lv girls!) and fastforward through 2 mos. of thread....

like the never consider losing attitude by blitzforce!

should get the license plate award "no fear"! and don't forget the ferrari kill silhouette for the side of the car!

congratulations on the race win and plundering of women (in my mind).....lol

I'm trying to figure HP for the cobra but its not adding up. I thought someone said 715 FWHP. Does anyone know what exhaust he was using? 133mph sounds like mid 500s RWHP.

Most builders dyno their engines under "optimal" conditions which could virtually never be duplicated once the engine is in the Cobra. OEMs rate their engine in the cars, as installed, with a much more stringent SAE rating. You usually can peel off about 100 fwhp once the engine's in the car. It's all about sales hype and bragging rights.
