At this time no track has kicked me out since the car has been well into the 11’s.
If it’s a NHRA track it requires a role bar at 11.99 or better and if it’s a IHRA track it requires a role bar at 11.49 or better. Typically most track aren’t to nuts about the rules when your just at the edge of the rules. Most of the tracks I go to are IHRA luckily. Although no role bar for my daily driven MM.
As far as running better in the cold we’ll see. It should go around 11.83 when the weather gets into the 55 degrees temps or lower with out the Nitrous hit. Although the Nitrous isn’t as evective when the bottle gets colder and the bottle pressure drops below 900. I’ve added a bottle heater and blanket in the last couple of weeks which tries to keep the bottle at about 80 degrees and 900psi. Although with the temps we’ve had lately and a black car, my bottle has been hovering around 1100-1200psi and is for sure adding about 80-90HP not 60-75 like I would normally think when the bottle is at about 900 psi or slightly lower.
I think in the cold this fall if I tweak a little harder and the cold tracks let me achieve my 1.6ish 60ft’s…. I could probably squeak a 11.3something out of it, and that’s it I think
I’m not really interested in adding any more boost because the 13.8psi I’m at now is no problem with the right tune on 93 octane for every day driving and abuse. And the Roots/Eaton blowers fall off sooner and become inefficient when you really start to over spin them. I think I found a sweet spot at just under 14psi with the blower and every day use. This is why I new early on I would be spraying it to go even faster.
My MM is the first serious effort I’ve ever made of throwing a shot of NOS on top of some boost, and so far I consider it no problem at all. The only thing I’m staring to see this past weekend is that my trans is not hitting 2nd gear hard enough any more at WOT. Its becoming more of a “Slide-Bump” instead of a crisp shift. I’m hoping to have a rebuilt/beefed 4R70W in it with in the next couple of weeks. Until now the stock trans is still in it with only a shift-kit. It’s done very well and would have lived longer if I could have made the 1-2 shift even harder right from the beginning. But that’s hard to do once you’ve installed a shift kit. It requires better 2nd gear clutches and more internal work.
Thanks for all the support guys. You should see the look on every ones faces when my car comes back down the return roads at the tracks after a mid 11 second run :awe:
It’s a mix of head shaking and high fives. At one time I left the car running in the pits to let it cool down and run the fan for a few minutes, People walked past it and would do a double take and say…. “hey, that car is actually still running”??? “ You cant even hear it running”!!! Man do I get a kick out of that. This car is really teaching me that a race car doesn’t have to be a undrivable, loud, trailer queen. The Nittos on the widened rims really do the trick at the track and are no problem in the rain so long as the tread isn’t gone, but that’s true for and street tire any way when its raining.
Thanks
