:)

that is very good for your mods.

you forgot to mention your 75 shot!!! :p


what is your elevation?

The track is 800'

The DA was -357' on that pass

5000 feet kills my car here i would run that on 125 shot

Dang, I couldnt imagine sprayin 125 on my car. Im too big of a puss to hook up a nitrous setup anyway.

Exhaust, gears, and a tune = 100hp over stock?

It did 259/289 when I first got it. Only mod on the car at that time was the cat delete and the skip shift had been eliminated.

I haven't been back to get it dyno'd but I'd be surprised if it did much more than 300. Still on factory 1.5 rr's, stock w/p, stock tb, and the tune isnt all that great. I wouldn't consider it anything more than a minor bolt on car.

The car stock wouldn't do any better than 14.30 at 97 with a 2.1 60' from what I can remember.

That's an impressive MPH. No other power mods at all -- just the exhaust?

C'mon son! how much you spraying:D

There's another guy on here that's at 12.5's with bolt on's only, nothing special about his setup... can't remember his name but he posts often... plus with an almost -400 DA it makes it even more likely.... might be running with some weight reduction though, fiberglass hood.. no spare or jack, maybe a back seat delete.

Longtube headers, exhaust, gears, tune, slicks, m6, -400 DA, great driver = mid to high 12's all day

I love how everyone is always so skeptical if anyone has a good run with an LT1... if it's anything away from the norm then "there's no way" but if it's an LS1 and it breaks away from the norm then the reason becomes "it's an LS1, they have so much potential it probably did run 11's with just a lid"

It's not the ETs that are unusual. That's a result of traction and gears. Traps tell the story of horsepower production and they went up a lot.

Like the OP said, the best traps before were 12 mph slower. That means over 100 hp came from somewhere or there was a lot of weight reduction in between. That's the great thing about physics -- it never changes. If the car gets x amount faster it took y amount of power to get it there.

I wonder if there's some head work in there or something? You never know what goodies the original owner left for you.

moroso cold air kit with an elbow. MSD cap, taylow wires, NGK plugs.

Ha, come find my bottle guy :)

About 16 lbs from the hood, no front sway, no spare or jack, no air pump (whoop de doo). Full weight car besides what's listed.

I like the way you think...

CAI and the catback I put on it with the gear change took me to 103.5 or so.
After the LT/ORY and said weight I took out, in the heat of the summer did 107-108.

Now with and cool air put me up about 110.

My first pass earlier that night was a 14.1 on a 2.99 60' (just seeing how the track felt) with the exact same mph as my best pass.

I'm positive the heads have never been off. My brother bought it from the original owner, which was a middle aged lady, and I bought the car from my brother.

And we all know a 359/389 hp car at 3450 race weight would trap way higher than 109. I'd guess more along the lines of 115-116 with the 6 speed. I don't know where this extra 100hp figure came from...

That's exactly why traps are such a good indicator of power while ETs equate to traction. The rule of thumb has always been that it takes ~ 100 hp to make a 10 mph improvement. While not exact it's pretty close for all but the most serious race cars.

You can't picture the middle aged lady wrenching on the car? :D

I have no problem believing his times and trap speed for the mods he has listed. :yes:

you're the other guy on here I was thinking of that was running 12.5's @ 110+ with a non-excessive bolt on car.

Woot woot!

What gains would I see from a set of 1.6's? Or maybe even 1.7s?

From your personal experience that is....

Second to the long tubes, the 1.6's were one of the best gains in performance I noticed. Lash them on the loose side and they are awesome. You would have to change springs to go with 1.7's and I can't speak to how much of a gain over 1.6's that you would see.

Definitely not the norm.

Congrats.

:)

Nice Times!

Get some LT4 springs and 1.6RRs.
Remove as much weight as you want.
They will do 115 (atleast) with just bolt ons!

Thanks guys.

My car weighed 3420 with me in it last time I checked.

Are the 918's better than the LT4 springs for a weekend car? My goal for this car is to NOT become just a track car. I want to keep it as streetable as can be. I realize valve springs aren't going to make it not streetable but as far as wear and tear (since the LT4's are factory stuff) how often do they need checked. When referring to the lash. I had planned on doing the RR's and EWP over winter. Along with new brakes all around (been needing these for awhile) so I need a good project to get me by for awhile to pass the cold season.

918s are good and would be lighter than the LT4s but cost more.
LT4s can be had for $50, the 918s are $170ish and the hardware for them can be had for $150. Just depends on what you want to do.
If just running the stock cam and 1.6RRs then LT4s will be good. If you plan on running a larger cam SOON then go with the 918s but if it will be a while then you will replace the springs with the new cam...

With lash, I go just past quiet when adjusting, screw down the allen lock and then about 1/8 to 1/4 turn of the nut to lock it down.

And I agree with Shon, anything more than LT4 springs isn't necessary if you are just going to do 1.6's in the foreseeable future.

3420 with you in it? Wow, that is pretty light already! Mine was 3640 with me and a 1/4 tank of gas. I was never much for taking stuff out of the car though, only thing I removed was the spare and jack.
