sorry i don't use street tires when i am at the track but my mtstreets are 10.50 x 26 x16 that makes thenm the same height as street tires,, yet they do grow to about 27" over 100 mph.

 

John I am planing on attending a couple of Hooked on Driving events this year as well as the Crossfire event in NC. I have been putting this set together for a while and picked up the 18" all around ADR wheels with Toyo R888 dedicated track tires set yesterday. We put them on the car to check fitment and then I drove it over to the twisties to check them out.

I could really feel the difference in accelleration over the 19/ 20"s. I had no idea it could make that much difference. The fronts are 225/40ZR/18 and weigh 40 lbs( bathroom scales) and the rears are 295/30/18 and weigh 48 lbs. No rubbing and a lot of fun. Probably did not get them heated up good so the best is yet to come.

I am sure there are much lighter wheels out there but I got this set up in my budget with the main focus of saving the wear and tear on the pilot super sports.

BTW I have a set of Hoosier P275/40R/17 drag radials that I have had for a while and yet to try. LOL.

 

just bring the hoosiers to me jim ill let you know how they hook!

 

what a limited running in the 11's,,, # 6 same as before # 7 went a little sideways on take off.

 

Not a problem Steve. Any thing for one of my car buds. I wish you guys from the "boro" could come to the GTG Dyno day in Spartanburg on Saturday but I understand it is a long drive.

 

im heading to cullman al. to swap dr's with black srt6 so i can leave my big brakes on the back. and my tcu is in houstoin for retuning on the tcu mod. big manis going on everything is thermalcoated gold to match the calipers.
if your not busy on feb 11 theres a open house at buckhead imports in smyrna ga. bunches of m/b and bmw going to be there. stop by!

 

Can't fool me, I would know the sound of that car any where. I have been behind it enough lately. Nice pass!

 

Well I finally found time to datalog and you guys were absolutly correct. Lean on the top begining around 5k rpm. Rob has the info and we will be adding fuel at 5k using the Needswings fuel management system.

thanks Steve, Grip Grip, Jim, Mimi and all who caught this and commented.

 

Hummmm, I wonder if he'd pick up a few MPHs if he turned off the air conditioner?

 

Should be a beast once dialed in, Jim!

 

Air conditioner on the track absolutly taboo! Outside air conditioning .

 

hope to see you sat jim. you will be one of the first to see the new drag pack! hopefully i wont have any issues. so many things going on at once my reliabilty seems to be suffering. i need to get some miles on the car
