My 347 Numbers

[86GT50]

Well, I am new to this site & let me say, im gonna be a daily contributor to this AWSOME site....... anyway....
I pulled my 100,000+ 302 motor & stroked it to a 347 with a Scat Kit & a set of Pro Topline steel heads, I have a Tremec 3550 & a 3.73 in the rear.... My best time before the swap with only bolt on's was a 13.90 & at the end of last year after the swap was complete (so I thought) I went to the track in November & right off the Trailer I launched at about 2500rpm & the car fell on its face & still ran a 12:00 even (best time so far). I talked to a dyno guy out here in Chicago & we have been dynoing the car ever since. We have changed the intake & Maf & several other items to get the car dialed in correctly & were hoping to run in the mid to low 11's come the warmer weather.........

Sounds good, so what kind of numbers are you putting out?

12 flat is pretty damn good for 1st time out. What is your MPH in the 1/4/? That should give a better idea of what times you can run?

The mph on my 12.00 run was @ 115 if I remember correctly. I was sleeping at the lights & the car bogged at the launch, my shifts were very clean, so with that, im guessing I should be at 11:50-11:70 if everything goes right...... I was changing intakes & injectors & just pulling my hair out...... so I've been to the track since then but I didnt have the car tuned correctly..... On a seperate pass my reaction time was .003 & I missed a shift & went through the traps at 108 & my time was 12:09.... so we'll have to see if I can lift the friggin front off the ground this summer...... I hate Chicago in the winter time....... my driveway is too short to practice.... or is it??????????????????????????????????

reaction time doesn't affect ET or MPH. This only comes into play against another driver in eliminations

You 60 foot times will affect et, depending if you are spinning bad or bogging bad.

What kind of HP #'s is the car putting down? 12.00's first time out is pretty good imo. This day and age, everyone is happy running 12.50's with all the parts you have, so I gotta give you a thumbs up so far.

Are you running this on street tires or a drag radial type tire? Radials will mph higher than a stickier tire.

Frekinstein, im running on a set of M/T ET Streets, 26x10's.... I Just put on a NitrousWorks kit as well. Come the warmer weather & we get the car back on the dyno to really tune it on the motor we are going balls out & gonna re-dyno it with the NOS

The last time we dyno'd the car back in August we were at 389 & we had to change back the intake & MAF & Fix a huge Exhaust Leak.....
So after the snow dies were gonna put it back on the trailer & go to the dyno again.... im hoping for at least 410 or better at the tires

Nice numbers! Before I put the blower on I was only able to get 270 at the rear wheels with heads, e-cam, intake, ignition. You cant beat a good tune!

tuning is the key... I have Bob Kurgan from the EFI Renagade NMRA class doing the tuning for me.... if you need a great tuning guy, he's the guy to hook up with, go to www.kurganmotorsports.com & you can get a hold of him from there.
