Thanks for the feedback MM. I have been in contact with Greg and Jeff. Jeff is the TT director for the SE region. They have told me to get my hp down to what I mentioned, use no bigger than a 245 tire, basic coilovers and bars with weight at 3150 or so and I should be at TTC.
I would be at a power to weight ratio of approx 11.6/1 and you are right that i wouldnt have much room for anything else.
It was interesting that water injection doesnt cost any points. No methanol can be used however---in any class--unless you run the open ones.
I would not TT without a real cage however. Not going at it to have a undisputed winner of a car, but rather a car that i would be honestly competitive with.
Maybe getting time for another DD?

 

Wow, good luck.
Can't you drive a car with a cage on the street?
I made 297RWHP with a stock pulley and no porting.

/NASA??? You won't be like the JATO guy on Mythbusters; will you?

 

297 with the small pulley? Damn--come to think of it i was pulling over 300g/sec myself.
It may be easier to just go TTB. max power to weight there is 10.25/1 i think and i know i can make that--plus have room for a better suspension tires---this is not a firm decision yet guys--just doing due diligence. But i think i am ready to go to the next step.
Most people dont realize with a little added power the 8 can be a force to reckon with.

Look at this vid with mike driving a na car

A question I have not been able to answer;

Do extremely high MAF numbers cause tire spin, or does the tire spinning and motor revving, cause high MAF numbers?

/Is this like the chicken and the egg?

 

Interesting. What HP mark did they set for you?
When I sent in my dyno (340 HP at the boost that I run on the track) and weight (3314 with me in it), they classed me to TT-C +14 and just counting in my suspension pushed me into TT-B.

lol

You serious?

 

Interesting how those classes are made up . Is it peak power they go on or "area under the curve " ?

 

260-275 range depending where my weight went. This is with BASIC coilovers and bars and tire size no bigger than 245. No other mods. That would get me to TTC+14 they thought.
I would hate being that close to be thrown into TTB or DQ'ed because there was cold air temps that day.
I think just giving it up and going TTB may be the sane thing to do.
I have heard about a turbo'd RX8 that would have placed 3nd in TTB if he had been running TT.
Track times where there.
you are under a 10/1 ratio?

Brettus ---its peak power after 3 pulls.

hmmm - not meaning to start anything but .........with turbo you could tune for a flat power curve and have huge advantage

 

It's based on modification and arbitrary decision making.
In our case, equipping the car with aftermarket forced induction means a director looks at our dyno sheet and weight and comes up with a "comparable" platform (in our case, the BMW 135i Coupe), which puts us in TT-C with an additional 14 point penalty.
6 more points and you are in TT-B with cars like the ZR-1 Corvette, Ferrari 348, Mustang Cobra SVT, Mercedes E55 AMG and Porsche 997 Carrera.
6 points are springs, shocks and a swaybar.

 

I guess you could dial back the power, but you would have to demonstrate that there is no way to increase it on the fly.

Yeah, I'm 9.2:1

Well, clearly a turbo set-up with the same peak power is always going to have the advantage over an S/C on a road course.

 

yes, but the advantage can be made even greater by tuning for a flat hp curve . If the number is say 280 you could have 280 from 6000 through to 8500 .

And it can be done without a boost controller which gets around the 'altering on the fly' issue .

 

Damn, think my engine is done. Doing some unspirited driving the other day. My car started misfiring, All my dash lights lit up, and I've got a HUGE smoke cloud behind me. DTC's P0300 and P204. Had car towed to house. Found LOTS of oil in intake and in spark plugs for rear rotor. No oil on floor and no coolant loss. I'm thinking I lost a seal. Any other causes perhaps?

 

I think thats exactly his point, in a lot of arguments

 

Sorry to hear that JSK---that sucks.
You can use the 09 short block you know?

No argument here that turbo offers more flexibility in a rd racing situation, every system has benefits and negatives of their own.
Dont forget to add the lotus (na version) and the Porsche 993 (non turbo!) thats in TTB
OD

 

No, it's not an RX8, but I can't let Denny have all the fun...

Yes, I'll be keeping my day job

Will it start and run? Does it sound like a motor boat?

 

Yep pretty much. Took a lot of effort just to get it from the driveway into the garage.

 

Sorry to hear about the problems, JS.

 

Mark and disconnect the coils from the ECU.
Remove the leading plugs.
Spin the engine and listen: do you here even pulses or PULSE, pulse, PULSE, PULSE, pulse ....

OR

Have a friend spin it with a finger in one leading plug hole; does it feel even?
Try the other hole; same test.

Sorry to hear about it, hope it's OK

 

the all dash lights lit up throws me here. On my blown engines I never had a dash light come on that fast?

Z baby---man the hp of that M3 shows doesnt it? Wow--tapping 160--now thats a different world. I would probably blow out all my wheel liners at that speed. Love the video set up.

The one thing I wish i could do is to increase acceleration from 115mph to 135mph. This car is pretty quick from 60 to 115, but after that you can tell its air footprint could be better.
Has anyone other that Juan installed the 09 underpanels?

 

It might be much easier and less prone to error to disconnect the e-shaft sensor. That way, both the ignition and fuel systems are not operational.

 

Charles, I still have your fuel pump tool. With this going on, I haven't gotten around to the fuel pump. I might just ship it back to you and get it from you again later.

 

You serious? any answers?

 

Semi serious.
I have noticed the data logs during a tire spinning pull show a higher MAF than if the tires did not break loose, but who is to say which is cause and effect.

 

So that was a serious question? lol

The MAF just measures throughput. Nothing "causes" it.

The motor is just an air pump. It passes a fixed amount of air through itself per rev. The blower is fixed-displacement, so it stuffs a fixed amount of air into the motor per rev.

Now, if you take some of the drag off of the drive train (i.e. the car), what do you think happens?
