13.382 1/4 mile. This was the best time today. I ran alot of 13.4's & 13.5's. I didn't remove any weight (spare, Floor mats, etc...) And had a 1/2 Tank of gas. I'm also on the stock dunlop tires at 36 psi. I think that with a mid-pipe and removing some weight I may be able to hit 13.1's.

 

is your car stock?
either way.. good times

 

no- I have an HKS exhaust and a Apex SAFC.

 

nice job

 

One of my 13.4 runs I had a chance to race a 335i. I was not very impressed. I never saw him break 13.5's all day. Beautiful car though!

 

what is the Apex SAFC
does it help?

 

Its a Air/Fuel converter.(AFC) It increases or reduces the siginal from the MAF to richen or lean the motor. I reduced the siginal by 8% which brough my A/F ratio from 11.5 to 13.3. Its just an old school way to trick ECU's. Their are alot of people that don't like them. But they've been around for years and are a proven tuning device. Many 500+ hp supras have ran these before stand-alone ECU's came about. I found a used on in great shape on e-bay for $125.00. And around and 1 1/2 to install.

 

you get it installed? 1 1/2?
is it hard on your engine does at all.. can you change it to richen or lean the motor whenever you want

 

Her is a really crappy cell phone pic for ya of the AFC.

 

Great time Jeremy. I added you to my drag strip journal in my signature and calculated your Density Altitude for the day, which came out to be -356ft. Your times seem to be right on avg with others who ran in similar DA. BTW..you listed custom intake... is that JoeZ or something else? Did you run with the stock wheels or the aftermarket ones? Also the mph is a tad slower than others, but that may just be the particular track or something to do with the A/F controller.

 

Yes and No! If you get it tuned then NO. But if you start making larger adjustments then you can really do some damage. You can lean the motor out very easily with this, so you have to get it turned and get used to using it. I have a wideband O2 sensor so I can tune on the fly.

 

Thanks, My intake is a K&N BUT I extended it into the front finder below the front head light for a true cold air effect. ( I really just didn't like all the under hood noise, this moved it outside the car,it sounds nasty)BTW everyone MPH's were slow today. I was with a 370 wheel hp supra and his MPH was only 110 at 13.3 also. Aftermarket wheels but with the stock dunlops. 18x9.5 rear
