Im not in any 1/4 class... Im just trying to get in the 9s LOL

 

congrats on the fast pass...9's should't be too difficult with a decent 60'.

 

Nope, you are permitted data logging equipment but it is prohibited for any electronics to alter the performance. That means no traction control of any kind no matter how you package it.

The Top Fuellers log driveshaft speed vs wheel speed vs RPMs etc and use it after each pass to adjust lockup and trim etc .. but not in flight if you know what I mean.

 

NHRA Sport Compact has a capacity limit of 3.5 litres anyway. Porsche 911s can't play!

For Pro RWD the max is 3.5L we are not talking about a Pro class, we were talking about Sport Rear Wheel Drive, actually we are taking about helping the fellow go 9s. and by the way launch control and traction control are two different animals.

Launch Control

Fully flexible first gear launch capability.
Extensively tunable to individual vehicles.

Traction Control
Fully adjustable from the dashboard.
Measured from all 4 wheels

 

Im not going to do any NHRA stuff LOl just having some fun.

 

You mean alot of fun ........in a very short time!

 

yes in 10 seconds or less

 

Correct, they (top fuel) also run timers that alter the run throughout. Quite funny when they first started using the rev limiters to limit top end speed. They mandated a rev-limiter, but didn't say you couldn't put it on a timer Needless to say after a certain top fuel team elapsed the national speed record on a rev limiter, they started watching out for that too.

NHRA SC rules differ quite a bit from NHRA's rules as well, they are under the same umbrella, but there is a lot more team input and they're changing all the time. Also on a boosted car with a boost controller and wastegate, you're already modifying the engines performance during the run, it doesn't say anything about adding another variable to this correction table. Back on topic

 

Now your talkin.

 

I don't agree, launch control is just a specific example of traction control.
But as other have said the Sport Comapct world is encroaching on the electronics bans .. might be inevitable.

My understanding is that the 3.5 litre capacity limit is for all Sport Compact classes?

However for the purposes of getting a good number, I guess any and all aids are acceptable.

 

Sure they can, just not 993, 996, or 997's.

 

Congrats on the run bro! Since we are 'skinning the same cat' with different approaches, I know your car should run a 9.6X with AT LEAST a 147MPH trap! It will come....

 

ALex,
glad that ur in one piece after doing a cross country run in a truck LOL

I think a 9.7 with a 146 mph is doable... if we get a 1.5 60 ft. run full boost I think it will hit it. the 10.1 run was at 1.32 bars.

 

Guys,

I just reviewed the rulebook for the Sport Compact Class, and it says nothing about the Sport RWD class being restricted to 3.5L. It actually gives no maximum displacement limits at all for that class. Only that the engines must be 4-cyl, 6-cyl, or 2-rotor rotary.

Now, under the "Pro RWD" and "modified" classes, there are a maximum 3.5L displacement sizes listed for 6-cylinders, but those are totally seperate classes than Sport RWD.

Thread-jack complete.
