BTW - running down the track with 15psi bias tires is very interesting!

You don't have to tell me that.....been there.

You know Joe, I was gonna call you last night but then figured you would be tied-up as you usually are on Friday nights.

I couldn't really keep an eye on the tach but I'pretty sure I was trapping at over 5500, but my focus was trying to keep the car straight at it was all over the track especially 2/3's to the end. I dont think I'll run less that 15 psi in there ET streets. I was shifting at about ~5500 for each shift. Just weird how 4th gear felt exceptionally strong - must be that Voodoo spell in Frankencrate's chest.

Best 1/8 was 8.1/89.03, but keep in mind that's with that stinking 1.9 '60.

I was thinking maybe putting on those el cheaop front shocks instead of the KYB's to let the fron end come up easier, but I think those no-hops would prevent it. When my car takes off, the rear "lift" up into the air. Not sure that's idea.

Vince
I have a book by Dick Miller Racing called "Need More Bite?"
It helped me get a better understanding of what is required to make the suspension work in our rear coil sprung cars.
I would gladly send it to you if you are interested. PM me with your address and I will drop it in the mail.

As a rule a stick car will mph more than an automatic guys car too Just leave like Joe Sp leaves, on the chip, dump the clutch

With street tires and a stick, it's practice, practice, practice. When I started racing again two summers ago, I didn't even have a line lock, and one of the lanes you just roll right out of. So its, burn out quick, beat the other guy to the prestage, get the rpms set and hold it there with the gas pedal, and hope/pray that you hit it just right releasing the clutch. It's a challenge, but fun (have since put a line lock on). Since I have QTPs now, I just dump it. WOT, baby. I run DRs on the street though.

Maybe you should get an M20 like mine? Shifts great (and only 134,000 miles on it).

The more runs you get in, I think you'll see your times keep dropping, just from practice and figuring out what works. I know that mine will improve a bunch, but I basically just had a few shake down runs with new suspension/tires, etc. this year and then the season ended.

Thanks for the ofefr Chris - I actually did read that. He knows his stuff, but he's coming more from a racing perspective - this is a street car.

I was looking for 120mph, but would of settled for ~115-117. Do you guys think that additional tuning will get me alot more power, or is a "signifigant" change needed? Looks like my car's trap RPM is just under 5300. I dont think were getting into valvetrain instability with this HR at 5300 but anything is possible. Think I need a bigger cam, or maybe a smaller cam to gain torque. Or, XR280/286?

 

[bracketchev1221]

I think 120 is looking to far. 120 is getting into high 10's power. I think for your E.T. goals of getting into the 11's you are making the power you need.

Slow down chief. Before you start throwing parts at it ($$) Look at your 60' times. Then look at some of your statements ;
"still can't launch this car"
"missed shifts".
I don't care what kind of power you have under the hood. If your stick car lays down a 2.0 short time,....you will not achieve your goals. Be patient. Work on the 60' times first, then you can go from there. It takes time. When you can find a good launch technique to get down to the 1.7-1.8 range, then be fast at shifting, you have a possibility of hitting the 11's. It don't happen overnight. :noway:

Hey Vince, it was good to see you last night. Congrats on your new bests. I know there are some 11's there if you get a good hook. Thanks for the kind words. I was very happy (not to mention a little surprised) with my results. I think my car likes the 4.11's. I also learned that a really good burn-out is essential to a good ET. All in all, it was a good night. A new best and nothing broken.:thumbsup:

yes Jim, but I like alot of MPH regardless of what the driver does

Rich, it was a pleasure watching your tail lights as I sat there and spun off the line...but I was reeling you in though! Did you get anymore runs in? My belts jumped off again on the way home on Rt.1, man is it dark on that road!

 

[Sid Coleman]

Rich, congrats on the 12's!! You'll pick up even more when they do a good track prep!
Vince, glad you had fun @ Cecil. You guys will have to post next time you head down, I'll take pictures!

I saw you coming up quickly! I left about the same time you did. I thought about making one more run but the staging lanes were pretty full so I decided to call it a night. Sorry to hear about your belt issue. Definitely pick up an extra set and keep them in the trunk.

Vince,congrats on some mid 12's :thumbsup:

IMHO you won't find 120 MPH with that cam

 

[GRN69CHV]

Vince and I talked at length earlier. According to the race calculators, w/ 28" tire, 3.90 gears and 1.0/1 4th gear, he was running just about 5300 at 113.16. Aside from a 60' time, he needs 115 as a target for an 11.70 which puts RPM at 5500 through the traps. Unlike my setup and dealing with converter slip in high gear, his car has "0" slippage in high gear. So realistically, there's two ways to look at this. #1 do you run more rpm all the way through and let the motor end up in 4th further down the track or do you try to run at lower RPM and torque it down the track (for lack of a better word). This is all still new to me compared to how we ran cars waaaaayyyyyy back when you ran "gears" and beat the snot out of it just to run a low 12. If he's only needs to run 5500 in top gear, I can alsmost guarantee the HP peak is well above that RPM.

Vince,congrats on some mid 12's :thumbsup:

Thanks Chris. Come on, I only need less than 7 mph, how hard can that be?

Wish I had more time to run the yellow spring...maybe it woulda made a difference who knows.

Sounds like you need the deep groove pullys. I had the same issues until I switched.
I also think you will make the 11's with better track prep on a warmer night.
Next year should be fun at Maple Grove

Man...Vince sounds just like me. Always wanting to change his combo up to find more power but wants great street manners as well. My first and only so far trip to the track was the same way. I was running 1.9-2.1 60 foots but still thinking about more power. More power will do nothing but make the car harder to hook up. So...Im trying to chill out and get the car to dead hook. Its just so damn hard to put the Summit catalog down!

 

[Teufelhunden]

Well Vince, I would have to say that you need more practice. We have nearly the same motor...real close and I can run my car down to 12.00 @ 115 with 1.7 60's. Are you sure that your tires were spinning? Once I went to the ET Streets I was hooking hard. I thought my tires were spinning too but it was the clutch slipping. Once I got bold and did the 4500 PRM launch my clutch let me know that it was finished.
I shift at 6000 or something around there. I just got a cheapy shift light so I can gain some consistancy.
I just got my TKO-600 back from Keisler and put the McLeod Street Twin clutch in the car. As soon as I can get to the track Ill post up my numbers. We should be running real similar to each other.

 

[mr 4 speed]

exactly and precisely what Jim said...get into the 1.7-1.8 range

 

[69-CHVL]

You have to remember guys, no track prep on Friday nights, and the air temp was in the 30's - real cold last night. I'm sure the '60's will come down when all those factors improve. Rich was also spinning bad with his auto and drag radials. Once we BOTH did massive burnouts, we both had our best '60s'.

I was definitely spinning off the line b/c the car was going sideways upon takeoff.
