Hi guys,
these weekend I manage to reach the third position in the starting grid at our local track race, but due to a slow and old motor, I don't succed in manteining the place. I notice that with the temperatures raising the handling of my car go worsening. The pace of the morning (40 deg asphalt) was very fast 13.6 (I do also the second fastest lap in 13.4) but at midday and after (more than 50 deg) I only managed to do a pace of 14sec.
What I should do in this situation?
this is my set up.

Did the grip increase or decrease as the track got hotter? And what changed with the car, did it start to push more or did it overheat tyres?

It's hard to say, maybe it started to overheating tires because the car wasn't bad to drive, however it wasn't as faster as before, and it was noticed by all other driver but in a less stronger way than me.
But I'm sure that the tires wasn't whistlling as in the earlier runs, maybe a decreased grip situation?
Some said that they had solved the problem changing additive from lrp carpet 2 to tire tweak.

Not true, LRP are excellent, I still have one motor (21.5) which we got in 2010, is still competitive & has been up to 110deg (when we ran turbo)

It really depends alot on the layout you're racing on. If your track is really small & tight, then I might lean more towards a 5.0 FDR, but(at least on the track at Mike's Hobby Shop in the Dallas area) on medium sized one, with a good flow to them, I'll gear closer to a 4.0, maybe even a tick more if the temps are ok. I'd say if you just not sure about your layout, then try something like a 4.5 FDR, & for the first run keep a CLOSE eye on the motor temp(maybe pull off the track every minute or two & check the motor with a temp gun). If it's staying plenty cool enough & you need more top end, then start to go to a bigger pinion(just take your time & go up one tooth at a time & retest it on track each time). Remember, each track is different, & not all drivers need exactly the same thing, so just go about it carefully & be patient till you find what works best for your situation....

If it's blinky, 4.0 should be safe, and you may need to go down from there.

If boosted, nevermind.

Additive may help, but I'd probably try harder shock and diff oil. The shock oil will look aft the tyres more, as will a softer spring.

I know I have been as low as a 3.7 on my car. Again all depends on the track. I always think a 4.0 is a great starting point and then gear up or down according to where you think you may be loosing a little on the comp.

It could be your motor fading from the increased track temp... LRP motors don't work too well when the track is already at 50 degrees.
Did you notice any changes in the tyres, did they come unglued?
Can you make any other comments on how the car was different when the track temp came up?
