Well guys, I'd like to thank you all for all your advice on how to run quicker in the 1/4!

Yesterday at Crail Raceway - U.K., I managed to run an all time PB of...

13.969 secs @ 98.5 mph (without nitrous assist.)

This is all thanks to a revised suspension setup and proper tyres!

Thanks again guys!!!

Cheers

Dave :cool:

P.S. How does this time rate as an SR20DE without nitrous?

Seeing that he listed his mods as:

Dastek Unichip (Mapped live on DASTEK Dynomometer)
Dastek Rev Limit Module (8000 rpm Fuel Cut-out)
Dastek Nitrous Driver Module

I'd pretty much bet that was more expensive than the standard JWT ECU.

Your cars weight is 2445 pounds with driver. You ran 13.969 @ 98.5 MPH with a 2.161 60ft time. You say your car makes 239 HP with 196 lb ft torque. Which would be about 207 WHP with 166 LB ft torque.



My cars weight with driver is 2605 pounds. My car runs 13.983 @ 101.5 MPH with a 2.265 60 ft time. I made at the time 200 WHP with 155 LB ft torque.


My cars is 150 pounds heavier and runs 3 MPH faster in the 1/4 mile with the same 1/4 mile time.

If you do the math your car is making about 180 WHP with 148 LB ft torque.

Another exaple is Steve Foltz with the VE. He makes 189 WHP with 150 lb ft torque. His cars weight is about 2700 pounds with driver. He runs 14.3 @ 98 MPH with a 2.3 60 ft time.

Please dont get mad at my post I am just wondering if the measurement of HP is diffrent over in the UK.

Look at the figures side by side.

----------------------------------Me------------- You----------
Crank HP---------------------228 HP----------239 HP---------
WHP-------------------------200 WHP--------207 WHP-------
LB Ft Torque-------------------175--------------196---------
LB Ft Torque @ Wheels----155--------------171---------
Car with driver----------------2605 LB---------2445 LB--------
Peak HP----------------------7300 RPMs-------7000 RPMs----
Peak Torque------------------6300 RPMs-------5500 RPMs----
60 ft time---------------------2.265------------2.161---------
Trap Speed @ 1/4------------101.5------------- 98.5---------
1/4 mile time-----------------13.983------------13.969-------


Just a comparison, Please dont get mad.
