I finally got car my car to the track. It’s a 99 ws6 a4 with yank 3600 and 3.73 gears. Stock weight. The car put down 460 to the wheels on the dyno. I ran the car twice at the track the other night and ran 11.80’s @ 117 mph. My 60’ times were about 1.75. I really thought the car would trap about 120 mph and get to mid 11’s. What do you guys think??

 

Any weight reduction ?

 

None.

 

Ws6 cars tend to be heavier than Camaros and some dynos read higher than others... so your car might be where it supposed to be. Weight plays a major factor besides the suspension....

 

What was the da ?

 

Even in shitty DA I would think that car should run 120mph. My car trapped 116 with 375whp in shitty DA.

 

What are your cam specs? Converter may be little on the small side.

 

My build is a stock bottom end ls1 with
tfs 215 heads
vengeance racing vrx5- 236/238 601/605 with 113 lsa
fast 102 intake
fast 92 tb
1 7/8” lts

2375 DA

 

my m6 car, stock street tires, 3.89 gears made 460. with 2.2 sixty foots and my horrible driving I still did 120 to 122

 

Was this at KRP? I can never get a number similar to what is posted in these boards.
Who's dyno?
Even with the 3600 converter you should be hitting the tires harder and with the top end you have, you should have a higher mph.
Since my car is broken, let me come take it for a test spin!

 

An auto is always going to trap lower than a manual. Also, spinning heavily at the beginning of the track can inflate MPH a little. I've done it before with a manual, and horrible traction.

Haha! Yeah it was down at Keystone. The car was tuned on Phil Smith’s dyno. After reading some posts I think I’m close to where I should be. Maybe with better DA and launch I can get my time down and speed up a few miles per hour. Seems like there are a lot of freak cars on here that trap 120 with 375 rwhp. 🤣

 

Idk....i trapped a best of 131.3 with 417whp (bolt on ls6) and knew where more mph was. There are methods to get it done.

These days a solid running bolt on ls1 should get to 120ish imo.

So yea. I would say op mph is way down.

 

Normal hiho post...

Did you not see this from ironmanLS1: Was this at KRP? I can never get a number similar to what is posted in these boards.

 

There is no way a full weight 98-02 fbody with full bolt ons is going to trap 120mph IMO. My trap speed is low by a couple mph. I’m looking for someone that is going to suggest better Da, a little higher numerical gear ratio, higher stall, or something else realistic. The one thing I don’t like is the rpm drop when I shift from 2nd to 3rd.

 

For comparison I went 1.55 60', 11.64 at 115 this summer. Don't recall the DA but let's say 2000'. I think I have it posted elsewhere. This is a 99 Camaro with a 5.7, with an LS6 top end, intake and 243 heads. Summit cam, UD pulley, Hooker Blackheart TD, and a 4000 stall converter, Racestar rims. I was still tweaking on it hoping to knock a tenth or two off, but broke a u-joint and transmission at the NOF race. It works well for what I have in it. I don't want to say the distance is off at KRP, either distance or MPH, but most other tracks seem faster. I don't have personal data to back that up, however.

It's no secret you can run down to Hagerstown or MIR and pick up 3 tenths.

 

You never get a number anywhere.

If you're modding a car to go fast and it6full weight you're doin it wrong.

Now with that said most run a drag pak.....that alone means not full weight. Still running a egr? One typically loses weught with Headers and exhaust to. Converter or clutch same weight as stock???? If so one really eff'd up there.

Seems pretty easy to drop 100+ lb and still be full weight.....weird eehhh

I have no idea how fast that track is or isn't. But you can leave hagerstown and mir and go to cecil and pick up another .2-.3 ......theres up to .6 we just riced math if you believe that ****.

 

Data log and you may see the car is pulling timing as it goes down the track. I know my car was a blower car but the IAT's definitely increased on the big end. I was able to get a 3900 lb GTO that made 490 on a mustang dyno to trap 123 in 3000 ft DA. But it was only after data logging and making tuning adjustments based on the data.
