Might be 2010, but I'm pretty sure it's 2008

I believe Mrslay got a 1.7 60' but that was using nitrous. I really need grippier tires. The last time I went to the track all I did was spin the 275/30 PSSs.

I've never had traction issues with my car. I think if you spray off the line the car can for sure 60' better, but without nitrous the car just doesn't have enough low end power.

what gears ? any tranny work? congrats car runs and sounds amazing..

I'm running stock rear end right now, and no I don't have anything done to the trans.

How are you launching the car? Mashing brakes and revving up to a certain rpm?

fwdGTP

Pretty much, I can get about 1950 rpm out of it before the car starts to push through the brakes and roll forward.

Very curious how long the tranny and motor will hold up at this kind of power level. Best of luck man. What are the plans for the future? Pushing it further or staying relatively the same?

You are running a 26 inch tall drag radial right?

I know it sounds weird but have you considered trying a 28 inch tall drag radial?

I know theoretically you wouldnt think you would need a taller tire if you arent spinning but believe it or not the taller tires tend to help the 60 foot a lot and the longer gearing may help your car utilize the power a little better in first gear. Also the tire tire will keep the tire flat when launch rather than cambered in.

Ive got a good bit of experience at the drag strip. My previous car was cutting 1.6s-1.7s on a 26 inch tall drag radial with no spin. After putting a 28 inch tire on the car I was doing 1.5s and even got into the 1.4s. Totally different platform but it may be worth a try.

I know the RCF that ran 10s wiith a supercharged did so with a 28 inch tall tire and cut a 1.6x 60 foot.

Just something to consider.

It really depends on how you launch the car. I'm running a 25" tire right now. If I put a 28" tire on this car it would be a turd. Tbh I question the validity of any times set at that track that they run at. I've seen cars run times that are just too fast for how they launch etc too much there. Watching the video the RCF that ran 10.8 and got a 1.6 60' the car leaves the line really soft which doesn't really make sense. I can't see how going with a taller tire could make you quicker unless you launch at way higher rpm and the sidewall flex is able to absorb it. My car can only leave at 1950 rpm, so it'll just be slow. I may run the shorter rearend sometime, it helped a lot NA, cut the 60 by 0.15 and quarter by around 0.3-4 sec. So shorter gearing does help this car.

Yea, honestly only way to know for sure is to get out there and test....not saying you are wrong or right, just saying ive been in a similar situation where the taller, heavier, should have slown me down 28 inch tall made me a bunch quicker lol.

And yea, a taller tire will make the car look like its leaving soft and care free but the numbers dont lie.

The car im talking of also is factory automatic, stock torque converter, leaving off idle at around 1800 rpm Has pretty aggressive gearing in 1st gear like the ISF....Im not sure if its just the bigger side wall of the 28 inch tire helps or holding in 1st gear a little longer helps, I cant really explain it but real world results is what I have seen.

I understand that it may not make sense to you and on paper, I would have thought my car would be faster with the 26 inch tire which is why I started with it but the car went significantly quicker right off the bat with the 28s.

Id be curious to see how the car worked with the shorter gearing and blower now...maybe spin? shorter gearing and the 28 inch tire combo might work good? This is why we test things lol.

However I will say, major difference in power/torque curves between the cars. My car had a roots style supercharged so instant boost/torque vs the higher RPM breathing F motor with the centrifugal superchargers that make more boost with RPM

Does anyone know if a 28 inch tall tire will fit under a ISF?

FWIW, at my track they claimed this was only the case if your car was stock.

So because my 2009 and 2013 vehicles were modded and went quicker than 11.50 they would give me the boot and tell me I needed a cage.

But stock its ok.
