As you guys know I recently bought a 98 Z/28 LS-1 A4.

Well, I promptly changed the oil and headed off to NED for a few trips down the track.

I made three passes.

13.865 @ 99.94
13.846 @ 100.33
13.836 @ 99.92

I went home and changed the plugs, fuel filter, PCV valve and did the free ram air mod by taking my sawzall to the radiator cover to let more air to the air filter and headed back last Wednesday to make some runs.

I was physched after the first pass as I ripped off a nice run
The only HPPIII mods were to have the cooling fans on early and to firm up the shift firmness and reduce the 2-3 shift by 200 rpm

13.282 @ 102.68 - ½ second and ~3 mph = not too bad for a $25 dollar investment
The other runs were kinda inconsistent
13.4 @ 102
13.68 @ 101.03
13.8 @ 100.91 (****ty launch, lots of wheelhop).

So the next thing I did was to plug the Hypertech PPIII programer back in and the only thing I changed from Wednesday was to install the "enging power tuning". Everything else was the same and the track conditions were pretty similar as I really wanted an apples to apples comparison and I was totally shocked by the results. 94 Sunoco on both nights.

13.372 @ 105.16 mph a 2½ mph improvement
The rest of the night the car was consistent as hell !!
13.354 @ 103.55
13.397 @ 103.44
13.370 @ 103.49
13.324 @ 103.47
13.391 @ 103.31

And my reaction times were pretty good too, hell I might give Uncle Ted a run for his money with the night I had
r/t's were:
.599
.549
.533
.526
.565 and a .440 red light on my last pass

I never thought the HPPIII would do anything as I had one on my 94 before I modded the hell out of it and I lost a tenth and a mph at the track but it consistently picked up 2 mph so it looks like the programming will stay.

Next up for the LS-1 is some autocrossing with TTA89

Marc

 

sounds like your finally having a blast with a car. Keep it up

 

That's cool. Let me know when you're going up again.

 

I tried to sign you up for the Auto X but its full. I emailed one of the guys running it to see if I can sneak you in.

I did pretty good on Friday as well.

Always just a step ahead of Marc

 

And so it begins.......again.

"$100 for the first person to catch me modding "the LS-1" other than the stuff above!!"

Who's going to be the lucky sucker to collect?

 

Oh No Mr. Bill

Didn't you see the disclaimer at the bottom of the message aka: doesn't count when the aforementioned mod came with the purchase of the car

Marc

 

I saw it....but after Mike's little jab....it's only a matter of time until the next mod.

 

Marc,

I have a 5177 (Think thats it) Dry NOS kit sitting here that I really want to get rid of.

I'll make ya a killer deal

Nah Nah Nah Nah, My Tow Vehicle is faster than your LS1 Camaro Nah Nah Nah Nah

 

Bill,
Will you accept $100 in McDonalds gift certificates

Mike,
I'll take the NOS kit

Marc

 

Nitrous is good. It was my favorite mod on my Z before the Vortech. Simple...go fast....me like.

 

TTA89 - if he doesn't want the NOS kit at a killer price, throw it towards a Maine boy looking for some juice!!

<<<<<< ME!!

 

Cole,
It's yours as I was only kidding.

I wouldn't put a blower or nitrous kit on the LS-1 if someone gave it to me for free.

Don't get me wrong, it's not that I don't like them but it's just that I already have one race car and all I want out of the LS-1 is to have a fun daily driver that you only put gas in and drive....no need to watch gauges, don't worry about it overheating, don't worry about it period....... just drive it and enjoy

Marc

 

sniff...sniff... our little Markie is growing up.

 

Cole,

I found a buyer for it yesterday. If he backs out I'll contact you.

I am not touching my truck anymore either, I am ahead of Marc and thats all that counts

 

Ouch that hurts
