Default Drag Racing Thread

I figured since most of us are avid racers, whenever the opportunity arises LOL, it might be an idea to get a thread going on the subject. Put up your times, and any pics you might have, we can also use this as a bit of an advice central with tips and pointers or just ask some questions if you're not sure about something to do with either racing or set up.

I'll kick it off with some pics from the last T'n'T at Heathcote on 28/2, managed a best time of 13.08 which is down half a seciond of my previoius pb, however I now have the 19's. Even my 60 foot time was down by .2 in the end, early on it was over .5 of a second, the new wheel size has certainly changed the way the car reacts off the line. However as an added bonus I no longer run out of legs in 4th just before the line, being able to get over the line with around 500rpm to spare.



Tyre pressures really played a big part on the day though, with the 18" T1R Toyo tyres previously I was able to get good grip off the line with as much as 26-28psi in the tyres. I found that this really needed some re-working, starting at 28 with very little traction no matter what I tried I eventually ended the day at 22psi, even then I possibly needed to drop down to around 20psi, however due to the "wobbles" coming on at de-cel I really didn't want to risk it this time. It could have had a little to do with the track as well to some small degree, as soon as I got beyond the 60 the rear just started to spin causing me to shift a little earlier than I would have otherwise.



Initially I tried as much as 4000rpm stall off the line but as soon as I was fully engaged and over the 60 it really didn't want to hold traction. As I said I eventually went as low as 22psi and was around mid 3000rpm off the line and slipping probably a little longer than what I had previously.

Obviously the new wheel/tyre size is making quite a difference, not only off the line but at the finish line as well, once I re learn the new set up hopefully the times should be much better than what I had done previously.



A big thanks to Johnny NoGas for the pics as well.

Hopefully the next time I send out a message some of you softies might actually come out, Rick made the trek (all the way from Bendigo LOL) with two of his boys, had a good chat, including what he thinks of my bonnet and he loves it : , was good to catch up, would have been good to have a few out there but maybe another time. The weather was actually quite good, even though it was pretty crappy back in Melbourne and no doubt some of you made a decision based on the local weather, always remember that Heathcote is usually the total opposite to Melbourne.

Anyway, that's my latest run out at Heathcote, it's been almost a year since the last time I had the F6 on the track but let's try to get as many F6s to the next T'n'T day Sunday March 14. Might be a good chance for everyone to get some practice in before the AFF drag day as well, that way you can get a better idea of time to use for your dial in.
