My last trip showed a 1.55 60' on the 100 shot, and i needed to soften that up.
Well i found away to soften the 60' up. I had 900 lbs of pressure and didn't prime the system. I also waited till 30' out to turn it on.

here's the #'s

1.644-60
7.036-1/8 ET
99.41 -1/8 MPH
10.982-1/4
124-1/4.

Goal achieved with a hyd cam of 460 lift. 218 @.050. This car could run 10.50's, but i would need a roll bar and a D-44 before pushing it any harder.

Pat you suggested the perfect cam for my app. thanks again. graemlins/hurray.gif

Mike

your track let you go 10.9s without a roll cage?

Awesome times for a very mild cam. Whats the rest of yours specs?

:eek: graemlins/thumbsup.gif

wow great numbers. what`s the specs of the motor? what car is it?

Thanks guys,

For some reason they haven't said anything yet..the guy in the ticket tower said ...this thing runs good ....that wouldn't of been my choice of words. I need the better D-44 rear end and a roll bar and i believe a 10.50 could be had, but that'll have to wait till another time.

oops, it's the nitrous HP 262 218-230 @.050

Mike...THAT is impressive!
Congrats on doing LOTS with less!
Proof that there is definately more than one way to get there...

What is the race weight? Those are great numbers, btw!

NICE TIMES graemlins/thumbsup.gif

Man, that impressive. I'm glad the cam worked out. Amazing what a small cam will do. Even the no-shot times are impressive. I bet she idles pretty smooth. I'm surprised, too about getting by without a roll bar.

Nicely Done Mike !!!

Darn nice! graemlins/beers.gif

thanks guys.
race weight is 3200 lbs.

Pat the car idles like my stock 2000 Ford Taurus. Very nice.

That's very impressive! Small cam, nice flowing heads, small shot, highway gears, cheap parts!!!! And more streetable than most 12 second cars I bet! Very impressive!

What rpms is the nitrous coming on at? and off? Just curious? Bob

baddbob,

On the 100 shot i turn the nitrous on right off the starting line from idle. I basically use a WOT switch and that's it. However on the 150 shot and the weak rear end i turned it on at the 30' mark, probably 300-3500.

The car crosses @ 4600 on motor , 5100 on 100 shot and 5300 on the 150. I shift at 5K on all nitrous passes.

As for streetable...well if it's there's no snow on the street i drive it year round I will drive it if there's snow piled 10ft on each side of the road, as long as the street is plowed ;)

Wow :eek: Looking at your combo, I guess I'll need to plan on a roll cage and parachute for my car !!!
Congrats on a very quick car. graemlins/thumbsup.gif

I hope you do. But remember my car weighs 3200 with driver.

i could use more gear and more nitrous for that matter, but NO roll bar here. Not for now anyway.

I remember anothewr guy at our track last year that ran almost every weekend ( the tower called him by name when he came to the line) and he ran 11.25 @ 122 and they never told him he needed a bar ???? It's definatly questionable as to how safe it is if something were to go wrong.

Mike, I'd tune for max mph before changing gears. Then you'll have a better idea of the ratio you need. There still could be more in what you have. NO2 makes lots of torque and too low of a gear could hurt. I'd bet your combo wouldn't want more than 3.55's maybe 3.73's.

Pat, i'm seeing that more and more. For instance i let my friend drive the car that very same day. I told him to leave it in drive ( shifts at 4K) and turn the bottle on once he passes the 60' mark.
I don't actually know when he turned on but the darn car went 11.82 @121MPH..talk about a freight train on the big end.

I would go no more than a 3.45.. but i do like the 3.08 for hyw driving.

That's a lot of mph. I run 11.60's at 114.8x mph. That kind of mph could win a lot of races smile.gif .
