[jnhj]

Just wondering what kind of performance to expect??
1/4 mile etc, with this combo:

1990 LX

- Automatic
- Vortech Supercharger
-7lbs boost
- 3:73 Gear Ratio
- MSD Distributor Cap
- T-Rex Fuel Pump
- Flowmaster 40s

Thanx J

Im assuming stock motor other than the supercharger? Ide say high 13s maybe low 14s on street tires, ifyou had some good tires you might see mid 13s. I know of a guy local that has heads cam intake with a vortec S trim on mickey thompsons with an auto that was runnin 8.9s at the 1/8th while my HCI NA car on same tires was runnin 8.2s. Its all in the combo and how well you can get it off the line. Go take it down the strip and let us know what it does!

88 LX w/Vortech V-3 SCI

I am in the process of installing a Vortech V-3 SCI on my 88 LX. It should put out 5 to 6 lbs of boost. How much horse power do you think I will see?

Stock block, heads and cam
Edelbrock Upper and lower intake
Shorty headers
Off road H-pipe
Flomaster 40 series muflers

Anywhere from 10-15 hp is the general rule for boost. I would say probably about 10hp per psi for a 5.0. may get about 300rwhp, give or take a few.

I am a prime example. Even though my is stick. And set up more for handling. But anyway, it all depends on how well the car is driven from the line. I can drive my N/A car with 230rwhp to same times as my 400hp car. It all depends....

I have seen a 5 speed car with just exhaust make 300rwhp on 6# boost

hey 7 Up stang, I'm thinkin more like 300 FWhp.

Yeah the general rule of thumb is 10 HP for every 1 lb of boost. So 7 psi is about 70 Horsepower. I used to have an automatic with full exhaust and gears thats it. It ran 14.7 @ 93 mph so Im guessing you can muster a high 13 at about 100 or so.

Reread the orginal post. Didn't see the auto part. Ah, should be close though, all depends on the tune. I wouldn't set him shy of 285rwhp. I would say 300fwhp easy.

I see low 14's/high 13's @ 100mph or less, good news tho...throw ANY set of aftermarket heads, even junkyard gt40's with an exployer intake and headers, maybe a cam if in budget...you will make a lot more hp!
