After my second rear end rebuild I hit the track again. Although I have a Kaaz LSD, Comptech billet steel bearing caps, J's 4.44 gear set cryogenically treated, and the differential housing cryogenically treated, I'm afraid to launch like I once did. I still need some strengthened axles...and some confidence in my current setup, to really drop the hammer the way I once did. Maybe that will never happen. Anyhow, I hit the track again today, and I didn't break anything. Here are the numbers.

My setup compared to last time...I am running less an over-tuned V-AFC that netted me 15 HP, with an eManage that is gradually adding 10% fuel up to 9K RPM, and with a J's 4.44 gear set. I ran the car very similar to last time. The highest I rev'ed to was 6,500 RPM and I slipped the clutch out (no dropping or side-stepping). I drove straight to the track (45+ miles) and did 8 runs with no more than 5 minutes between each run and I did not warm my tires up for each run. This was not an attempt to get the best times I possibly can, but to be consistent and compare data to last time. IMHO, today's test confirms that the J's 4.44 gear set is good for roughly 0.4-0.5 of a second in the 1320.



Compared to last time:




Do not post "why are these times so slow?" This information is being posted for only those who actually know what they're looking at.

 

Good job!

 

Nice runs. What were the track conditions like? And can you go over what mods you have again? If I remember right, you were Comptech Supercharged.

It is nice to see you running again. So after it was all said and done with your latests mods (rear end) how does it feel?

 

nice, this is great info

 

Comptech SC @ 6 PSI
B&B Triflo Exhaust
ProFlow TB
Greddy eManage (just adding fuel)
Kaaz LSD
J's 4.44 Final Gear Set
ACT Clutch & PP

Temps were in the 60's with humidity in the 80% range.

The rear end feels good, it will take much more months of abuse to really see if it holds up.

 

Great consistant times, definate improvement in the 1/8. Hope it all stays together for you. Keep us posted on your future runs.

 

Now excuse me if I "don't know what I'm looking at", but why are your trap speeds so slow (I could care less about the E.T.)? An improvement of 3-4 MPH in the trap speed over stock with a SC and bolt-ons really does not seem impressive (and BTW, trap speeds are not really dependant on a good launch).

But what do you mean by "The highest I rev'ed to was 6,500 RPM"? In the context that it was in, it seemed like that was only during the launch. If you shifted gears at no higher than 6,500 RPM going down the track, then those are some damn impressive trap speeds, and you can disregard the above paragraph.

 

imagine if your 60' was 1.5 . This is solid info, and shows plainly the achilles heal of the s2000 is traction. You have to have monster power to come back from that! Thanks. Have fun!

I am *very* interested to hear how your new diff setup holds up.... keep us posted!

 

Looking good bro...Man those J's gears are looking better and better...
