I've been driving in the NASA Time Trial series since it started in Arizona and have driven in about every class with a bunch of different cars. The only class I haven't participated in is TTC, or Time Trial C, which has a track record that so far no one has been close too. There's probably a reason for that, as the TTC record of 1:10.48 is held by the undefeated TTC national champion Greg Greenbaum, in a Dodge SRT4. Greg holds the TTC record at every track he's driven and as I said, has won the NASA Nationals in TTC since the National Champ event started two years ago.

Mid-fall I put my plan together to make a top TTC car. After reviewing about 20 different cars and reading the rulebook a million times, somehow I landed on the S2000 and thought that would be the best car for the job. In 2007 the S2000 started out in TTD*, which gave me plenty of room to move the S2000 up into C and do the mods I wanted.

The benchmark is simple, as the current TTC leader is a national champion. Unfortunately, in 2008 the S2000 got a bump to TTD**, which meant I had 7 less points for modifications.. so now I have to beat a national champion by doing *less* modifications.

I found a the perfect car for this: A white, mint condition 2003 with 19K miles. lol.



The goal is a 1:10.479, as that will beat the current TTC record of 1:10.48. I've never driven an S2000 at PIR and so far no one has really been close to that time, but no one has given an honest effort towards the TTC build either.

Currently I have 24 points of modifications available. And currently, the car has the following modifications:

• Bilstein PSS9 Coilovers (9 points)
• Tananbe Front Sway Bar (2 Points)
• AP2 Wheels (0 Points)
• 225 Front, 255 Rear Azenis Tires (1 Point)

12 Points total. According to the NASA rulebook, 2810lbs is the minimum weight the AP1 S2000 can use for TTC. I have to find a way to get down to that weight (with driver) without cutting the car apart, hopefully.

The Azenis aren't going to be around long, so I'll get my 1 point back from that. In this thread, I'll cover the other modifications I make to ideally build it for TTC and hopefully, beat that 1:10.48.

 

I look forward to reading more about your quest for the best. For us non-racers & wannabees, what points are associated with what mods?

Exhaust = ????
Boofster haircut = ?????
What about lightweight wheels?

 

Howmany points are you going to use for rcomps?
oh, and how the f* can you lose 200lbs of weight!?

You might as well help me build mine for TTC since it's not so pretty and co-drive!

 

Well, the important things breakdown like this:

Header - 2
Exhaust - 1
Test Pipe - 1

Sway Bars - 2
Shocks - 3
Shocks with remote reservoirs (PSS9s) - 7
Springs - 2
Strut Bars - 1 each

(how come everything suspension related starts with an "S"?)

DOT "slick tires", like Hoosier, Kumho, BFG - 10
Wing - 3

Brake pads, final drive and weight reduction as long as I don't get below 2810, is free.

The rulebook has point assessments for literally everything, but a lot of it isn't important, or not applicable to the S2000 (like solid axle replacements etc).

So given I have 24 points to play with, you can see how it works. Point is to find the best way to use up the 24 points. The PSS9s is NOT a good way to use points. It has an external reservoir, so I have to take 7 (instead of 4), even if the reservoir doesn't do anything. I could switch to a KW, Koni or other, get the same performance and get four points back to use elsewhere.. which I will probably do.

Tires are usually the best way to use up points. My S14 240SX ran 285s, my previous E36 BMW ran 285s.. both are TT record holding cars. I thought about going to the 285/30R18 on the S2000, but there aren't enough points left in TTC. I'm going to start out with 245 (since Hoosier doesn't make a 255) and see how it is.

For weight reduction, all I can do easily is the passenger seat, spare tire, tools, trunk carpeting.. then of course I could remove the stereo, A/C and more. I'm going to add an exhaust (1 point) simply because it'll reduce a bunch of weight.

 

There is a thread in the Racing forum section that has people's track setups. Maybe something in there can give ideas.

2810 doesn't sound that low. Is that with or without driver first of all? I'm guessing with b/c I'm at 279x without my fat ass.

Can't wait to see your car out there and maybe coming out for a ride along to be schooled. I'm hoping you will finally show them it can be done with an F22 instead of that AP1 junk

AP1 for life, sucka!

 

Haha! Nice thread title BTW. Congrats on the new car Brady! Definitely looking forward to seeing you put the smackdown on Greenbaum's record. Let me know if you need any help with the car. See you out there in March!

Aren't the AP2 wheels bigger/heavier than the AP1s?

 

LOL mah bad, your headlights fooled me. I knew it was 04+
