BTW - I just looked at you dyno sheet and that looks like a rather risky AFR on boost 12.5-13.0 is a little lean for my blood.

 

holy crap thats lean on fi, i never ran more then 11.5 a/f on my tt supra

 

Same wheel setup I always run. 15x8 Weld prostar w a MT ET Street 26x10.5x15... Weather was about 65 degrees, 40% Humidity and BP was about 30...

 

These motors can handle that with no problem and it still shoots out fuel when I get on it... As you know, their are many aspects of tuning that come into play... Allthough every tuner has their own theory and method, I have been using my tuner for a long time and trust his knowledge.. He does tuning and research for BMW North America as well as builds all of Fords Sema Trucks. Including this TT monster...

Oh, and thats the intercooler in the front and the radiator in the tailgate of the truck.... It is sick and was all hand built and fabricated in 6 weeks...

 

VERY NICE!!!

Are you running the stock axles back there?? Mind posting up a list of things that are done to your car? I didn't see anything in your profile...

 

Performance mods include-
APS TT-tuned to 9lbs
XERD Cat pipes
Injen Exhaust
UR Crank Pulley
MRC Grounding Kit :-)
CM Stage 3 clutch- being upgraded soon
Nismo GT Pro LSD @ 60%
Autometer- Boost, EGT, OIL temp, Fuel Press, and Intake temp guages
AEM Wide Band 02
Blitz Turbo Timer/ Peak Boost hold meter
Suspension /Brakes
Eibach Springs
MRC Camber/Traction Rods
JIC Strut Bar
Racing Brake Rotors
Hawk Pads
Inside/Outside
Nismo Bodykit
Roja 19" Formula 5's
Weld Prostars for racing
Polk Audio/ Kicker sound system
+ a few other goodies...

Hows that list !! :-) And yes, stock axles, I have already broken a cv joint racing back when I was NA... So I launch easy now, around 3500 rpms instead of 6000, and I roll off the clutch instead of dumping it... Thats one way to save the axles....

 

Ahh, that is what I was thinking. I couldn't imagine the 350z axles holding up to repeated 5K+ clutch dumps on slicks. If you could manage one, I bet you'll be seeing 1.5-1.6 60 fts and some nice 11.5's or lower!!!

Who did your install and tuning for the Unichip??

 

As many know, I am "involved" with MRC Motorsports in NJ. All work is done there and all tuning is done at IDA Automotive in Morganville..
And yea, the stock axles are ok I guess, but usually break the splines right off in the hub.. I had a weird case of actually breaking the cv joint in the boot coming out of the rear... I have an extra set of stock axles out of our parts car but am not reday to break mine yet..!! Very soon though as I will be doing a new flywheel and clutch within the next couple of weeks.. The CM stage 3 finally let go yesterday.... :-(

 

hey one3502nv, what is the backspacing on your weld wheels??

 

Well I have posted this many times before but I am always trying to help where I can...
If you are running a 15x8, then you need a 5.5" backspace... If you want to run a 15x10, then you will need a 6.5" backspace.. I am running the 8's with a 10.5" wide tire but either would work....

 

sorry about asking a question that has obvisouly been asked many times before..but I can never find any useful information with the search function about what wheels guys use with slicks.

I ordered a set of Weld Prostars today in 15x8...but I got the 3.5" backspace...I'm assuming these won't work and I'll have to send them back. Any insight?

 

Briguy,

Where did you order your slicks at? Total price? Let me know as I've been trying to locate some. Thanks.

 

Jegs.com...total price with 2 wheels and 2 slicks was almost $800.

 

Please don't take what I said the wrong way, not my intentions at all. I am here to help whoever wants help... I just remember there being athread in the racing section not that long ago about slicks... Anyway, yes, I don't think a 3.5bs will work... A 5.5 fits perfect, and is the exact same setup that a newer mustang takes.... I just looked at summit racing and a 15x8 with a 3.5 bs is equivalent to a wheel with a -25mm offset. and a 8" weld wheel with a 5.5" bs has a +25mm offset... So I don't think that it will even bolt on in my opinion... Sorry...

 

damn...oh well, thanks for the input. Jegs ships so goddamn fast that I ordered the wheels and tires @ like 4:30pm yesterday..and they were shipped yesterday afternoon so I didn't even have a chance to change the order.

 

Thanks BriguyMax

 

Do you drive the car on the Slicks to the track or do change tires there.
Since there is almost no space in the trunk that seems to be a challenge.

They say even though they are street legal they are not for highway use...

 

I once drove up on some e.t. streets, only about 30 miles though. Speeds as high as 70 mph on the way there. I set the tire pressure to 20 psi for the drive up. What shocked me the most was how much they "float", just driving 50 mph in 4th and giving it gas sends the a$$ into a wiggle, you are always correcting when driving on slicks. Its almost like driving on a flat tire, if you stay on the gas, its easier to control than if you vary your speed. If you dont want to drive up on them just have a freind take your slicks and a jack up for you, thats what I did last time I went to the track.

 

Just installed my new Fidanza flywheel and ACT clutch and the car feels better than ever... I will be testing and running next weekend at raceway park nhra Spring Nationals if anyone wants to coem down and race or just check out the car....
Thanks,
Jason

 

Nice times. Im workin on a destroked 3.5(will be a 3.2) with all OEM parts i think that will handle alot more abuse then the 3.5 itself, there is a maxima thats boosted (vq30 stock internals) running 11.5?@12?
