very well done

 

Are you running ballasts to get the weight up in TT4 trim (about 3,380lbs)? Down the road, I might want to try TT4, so want to see what sort of adjustments I need to make.

I suppose if staying in TT4, you wouldn't need to remove all that interior except maybe for the purpose of offsetting the added weight of a cage?

 

yes, i have ballast in the car to get my competition weight to 3401 for TT4, since i cant get the power any lower. if you can get your power lower, i would suggest 3301 competition weight.

 

Thanks. It is interesting that you will need to basically run stock power with added weight to get in TT4.

What tires/size did you run in TT4?

 

255/35/18 R7, they are same tread width as 275

 

I’m surprised you can’t lower your power with just a simple restriction in the intake or exhaust?

 

restricting exhaust will effect turbo spool and increase exhaust temp. adding restrictor to the turbo inlet is possible but i didnt want to mess with that. i had and evo 8.5 turbo that i was going to put on, that would reduce top end flow, but still have the larger turbine housing.
