Well 305/35/19 tire I never thought I'd see it grab. Granted from a dig or 20 MPH no it won't grab but a 1st gear slam at speed (30/35ish) I was kinda surprised.

26psi, 84 degrees out (gotta love FL in winter) and that was all I needed was warmer pavement. Had to shut it down merging onto a straight on-ramp but you get the idea...

For the "mild build guys" (like me) with blower, headers, meth not a bad tire. Ran it through some light rain as long as you're "not stupid" it handles decently. I didn't have the car going all over the road like others would make it out to believe. Sure hit a big water puddle you're in trouble but basic mild wet roads it behaves great.

Anyways...yeah...video...and don't mind the air/fuel I'm getting it retuned I see it's leaning out...

I was about to say heyyyy that looks a little lean to me!

Nosferatu

yeah well the sensor is on a delay but still I was kinda surprised to see that to be honest...off to get a re-tune. It was fine in the 45 degree weather...it's not happy in 85 degree weather.

Either way lean makes more power and she still grabbed

I don't even get traction with half the HP on street tires LOL.

that 2nd gear is crazy quick too!

they're probably the best tire you can realistically drive on the street imo. They age pretty bad though, so the final 1k miles on them is maybe 60% as good as the first 3k miles, or something like that. I've only heated them up with a burnout once at the track and that had a dramatic improvement where my car went from not hooking any part of third gear to hooking all of third gear. Sweet spot for street driving with max straight line grip does seem to be about 25psi for me too


I've been thinking a "ghetto traction control" could be to set the dashlogic to show the % throttle on the HUD or DIC? and then just aim for the max % of throttle to be applied in 1st and 2nd gear and target that

neverstop

I would think it would get more rich if hotter out and air less dense?

Nosferatu

good idea!!!

I don't know how much validity I put into DashLogic's output of the wideband to be honest with ya...I'll have it tuned again at some point and take a peak.

time to get some 60-130 times!

MTs are far superior tire and work great on the street. Nittos are good though.

Hooks nice, your car sounds real nice.

That's not lean, it's holy **** pistons on the street lean.

Agreed on how they age, im at that point currently. I used to be able to hook first gear at certain speeds but now a little over a year later nothing in first. But if i do a quick burn out theyll restick. But ive still been happy with them especially since i kept my 19s back there.

schpenxel

Mine used to go leaner at higher temps too. Some tune adjustments should get you fixed right up

Nosferatu

Thanks...that's the B&B Fusion with the the valves closed (e.g. quiet mode). Really let's you hear the blower. Sounds like a whirl wind or a treadmill conveyor belt at full tilt

Here's how they sound valves open (less blower sound more engine sound)...second half of clip is inside my car down the Federale Expressway en Mexico.

good to know im looking for a street tire for my factory 19s but my car makes over 700 on pump and will be in the 8s on e85

You're lucky then I am, I used to have to roll into it in 2nd gear for it not to break loose. If I just stabbed the pedal it would fry the tires instantly when I was at 623whp N/A

Yea I have the same tires and same gearing I can't hit it like that in 1st

I have Nitto Invo's, about to put in some boost when my Maggie gets here. I guess they will be a problem. I did install a Vitasse throttle controller and am curious if I can dial in some lag with it to help with keeping some traction. I'll let everyone know how that works out.
