No need to take everything so seriously Tomcat. 11 seconds is seriously quick.

At the end of the day your car is a kit car and so is mine. They were not made by Ford or $helby. 95% of the population probably don't know what the car is, never mind what is under the bonnet!

As you have already noted, fast times at the drag strip or circuit tend to come after plenty of practice and good setup. I hope that a few more of the Chevy guys get out and sort their cars for good times in the future.

I would be happy with 12's for my stock LS1 when I get a chance to race.

Ben

G'day All,

My RCM weighed in at 1180kg with 1/2 a tank and without a driver. It didn't have the twin hoops fitted and no interior trim.

Cheers
Al

Lets say an average of 1250Kg which is some 100Kg (230Lbs) heavier than say a heavy CR (1150Kg) or some 300Lbs heavier than say a Harrison.

Tis an awful lot when you comparing apples to apples on a track.

hey gav, thanks for the compliment, at first i took it the wrong way , because i always thought the saying was, its not to be sneezed at', not , its nothing to sneeze at. which to my way of thinking was the opposite. then i thought s**t he must have a preeetty fast cobra if he thinks mid 11s is ordinary. tomcat

hey boxhead, posting photos to email is the same problem, my wife managed to work it out several months ago when we posted a car for sale on the web ,it took her a couple of hours and i just gave up and havent tried again. ive been pretty busy but i will endeavour to learn how to do it, and you will see that time slip. tomcat

Nothing wrong with mid 11's Tom.

I wish I could get there, my chevy powered slug is a long way off that sort of times, I will blame tyres and driver.

No worries Tom.

Hi Tomcat
Just out interest what size tyre are you running? Are you running slicks? Jag rear? mid 11s and 121mph suggests a lot of wheel spin or to tall gears.

hi allfie, on the street with my old engine [ flat tappert cam ] i use 295/50/15 radials, 26inches tall. pulled an 11.8 116mph revving to about 7000 or more with plenty of tyre spin off the line if youre not careful, same engine with solid roller revving to only 6000 rpm, i fitted a worn set of mickey thompsons et street grooved slicks 28 inches x 12.5 wide on 15s running about 14psi. they just launch you without any tyre spin , unless you load the revs right up. i dont even bother with a warmup burnout. 11.5 118mph short changing 2nd to 3rd, not using tacho. the 121mph came from holding it longer in 2nd.car setup is race built c4 auto 3 speed fully manualised with hurst shifter, jag rear end 3.66 ratio clifford locker.carby is a barry grant 850, my 60ft times arent that good because i use a edelbrock super victer intake which are not good for making torque down low, a performer manifold would be better. i wanted engine longevity and it makes all its power by 6000rpm [old engine 7200rpm] oh its spinning a cleveland crank in a windsor block with a nicely ported set of victor junior heads. it really is a very mild cam and is impeccable on the street and beautiful to drive. regards tomcat

Hi Guys, thanks for all the help, especially Boxhead with the tutorial. I have now got some photos in my gallery and a good friend walked me through it. Here is a photo of my car and that elusive timeslip!
