Thanks :) there is a good chance I will . I really need some clean laps to see if it can go a little faster

Anybody here running tracks in the Northeast?
I'm running a 1:14.8 at NHMS w/ South Oval.
Car is a blueprinted S52 swap, full cage, gutted, BBK, etc...

Still running the dum as dog shit OBD1 ECU so haven't bothered. I have a Vipec standalone ECU i've been trying to find time to install and will certainly have her on the dyno then. The tuner who recomendded that ECU to me has made 250 HP at the wheels on a dynojet in an otherwise bone stock E36 M3. He is fully confident i will be putting down over 300 to the ground then. :)
Sweet video!

bone stock .....250 whp...???

can u pm the tuner info/connection?...

I see u r in beacon....Im 35 min away off 84...Somers

1:13.44 in final practice, though I couldn't quite put a 13 together for the TT. I forgot a few things and went slower, wound up with a 1:14.04 and like 0.16 off T80 second place. Oh well, there's always next year :)

You are taking some interesting lines; for instance, you can carry a lot more speed out of 10 if you track out fully and ride the inside of 11. I preferred hugging the inside of 9 as well as it is a shorter line.



250whp out of a stock S52 sounds very fishy to me. That's generally the ceiling of full bolt-on territory including intake manifold. Maybe he meant stock internals?

wh...


is she a bit loose..?

what susp set up?

geez that track does not look appealing to me at all....

[berlow94]

Nope, bone stock meaning bone stock. Saw it myself.

My track wheels are a set of Apex ARC-8's, my street/show wheels are a set of Compomotive TH2's.

Wh33lhop: Saw you at COM's, didn't get a chance to come over and talk. Definitely two different driving styles in two differently set up cars. You could also be turning in at 3 much earlier and carrying more speed up the hill. Also no need to lift coming up over the hill by the treehouse.

I didn't think it looked appealing either until I drove it. Very fun.

Car just had a lot of power and very little tire. GCs 550/750 with J-stock valved billy sports, 3.5 camber up front, about 2.5 in rear, 225 RS3s. Also a reverse rake since Fred didn't want to cut up the E30 M3 spindles to fit GCs on em, so the rear roll center was likely much lower than the front. Loose cars don't bother me much though.

Ah nvm, he had a standalone. I'm still skeptical but that makes things more believable.

Alright, wall o' text. Ready?

The ABS didn't like the bumpy braking zone into 3 so I overshot turn in about half the time, but I managed to turn in earlier on the timed laps if you watch those. Interestingly comparing the data shows that turning in earlier, though a shorter line, was 2 tenths slower for me on the exit. Maybe there was a bit less grip available on the inside line, or maybe I wasn't aggressive enough on the throttle coming out of it--you really have to meter the power in this thing. I was coming into the bowl at about 97-99mph.

Treehouse was the very top of third pulling .9G at 88mph (delorean style!), that took some balls, haha. I'd rather not ride the limiter in my friend's car--I felt that was plenty fast with street tires and no aero. :) All things considered, after watching the videos and viewing the data I think I could be in the mid-high 1:12s if I nailed everything juuust right.

Do you run a datalogger? It'd be interesting to compare data from the event and see where we gained and lost time, more power vs. more grip. :)

Haha, the two things i forgot to bring with me to NH was my jack and my data logger. :(
I see that the car is a ZF tranny with a 3.46 rear end. (same as mine). Not sure what they dyno graph is of that motor but im definitely in 4th as i come out of 7. One thing i've played with lately is staying a couple feet left over the hill. It lets you cut across the off-camber vs. trying to fight it.
My car also has no ABS, stiffer suspension, and a very fancy diff which does wonders accelerating out of turns.
Tell Fred to corner balance that thing!

[FredK]

Ha, I've been a little busy these past couple months, so I haven't had much time to so the things I wanted to do, like get a replacement camber plate spherical bearing, and a good race alignment. I just set toe at 0 at home.

Hope to see you around next season! Feels so far off now.

[Wh33lhop]

s54 pulls past 8k dude, you'll usually be in a higher gear. fred can do whatever he wants, I was just happy to drive the car :)



hey fred, get it corner balanced

and maybe get some r1s too
