Car Falls off after 5-7 laps

Fuel burn off, making the already entry tight car even tighter where it loses speed? E-85 or alky?Tires coming in where it makes the car even tighter thus loses speed?

We run 112 gas now that's what motor was set up on when bought .

It isn't unusual for tight entry cars to be fast at first. They build RR heat faster than the other cars and start working quicker. Then, the RR overheats and they fall like a rock.

Tight entry, and 3 to 4 lbs build up on RR. I would say he is throttle steering the car on entry to much, and once that RR increases it begins to make the car loose off, added stagger, hotter tire etc. Throttle loose, more gas, more it comes around.

Loosen entry, softer RR spring, more RR lower bar angle, more LR lower bar angle or LR spring stiffer, something along that line. He needs to be able to turn the car in and not have to throttle monkey it with the RR.

You've got a good car but you probably need to make some spring changes, not sure what shock package you are on but Jamie's is pretty good. Get that tight condition out of the car and you see some major changes through the race. Several other factors as well but like everyone here has said that tight car is gonna take off good and fall after a few laps.

Thank you to everyone that has replied ! I have a direction to go in now !!!!

Thanks Matt49 this happens even w new tires ! Start of race, restarts its fast and we can make up ground then goes away.

Have you done any tire temp readings to see what you've got? Might indicate a flaw in the setup. Many, many people make the mistake of adjusting into a, "Jack Rabbit" setup that comes on quick, but within a few laps they fade because the setup wasn't really balanced like they thought. Kinda like trying to race your qualifying setup, won't work for long. Its also true that the driver may be getting fatigued if he/she is older or out of shape. The newer cars/setups demand to be driven hard in order to work right, so if the driver is getting winded, might not be able to push as hard... Another possibility is concentration, some drivers are great qualifiers, but after a few laps can't find their rhythm. Do laps time just gradually decline off or do they go all over the place? If the times are erratic may be a concentration issue. Just some thoughts to consider.

Highwayman, driver is young and we never qualify good. The last two week we have be better in qualifying, and in race mode. We found rear 4 bars were in a bind at full drop. From that we made better runs last two weeks !!!! The adjustments we made was felt by driver and in the stance of the car was seen.

ill have to agree with masters on this one
i still get greedy even today and have to remember not to over tighten the car, ive lost 3 races this year being greedy(started on the pole), while a tight car does feel better to me its not fast consistently lap after lap (we have tested this) you shouldn't have to force the car into the corner, if your dragging the brakes fine but if your having to jab at them to get it to turn, its to tight
