I'm talking Full Intake / Full Exhaust, Underdrive Pullies if they're worth it, 160 Thermo if it doesn't keep your car SO cold that it continues to run on Open Loop.

Thing is this is my first 300 + HP Car and the more I drive it the more I realise 400 + HP is quite useless on the street unless you compete or race because even half gas is more than enough to blow most cars around you away... So I was just looking for a fun little streetable but somewhat economical boost in performance...

I was also thinking 3.42's or 3.73's with some good tires would make things a bit more fun around town but how will the stock 10 bolts hold up to that?

 

the stat is worth it, mine runs right at 175deg in the florida heat with it.


with full bolt ons and a dyno tune....350rwhp is pretty doable.

maybe a bit more if you count 1.8rr as "bolt on" but most guys don't

 

A guy around here with an 01 SS (i think might be an 02) has the SLP lid, SLP longtubes, y-pipe, offbrand muffler and thats it, he put down 357 rwhp, and right around the same rwtq. Its a 6 speed also. He has more bolts on to go if he wants too!

 

Holy crap how did he achieve that?!?!

 

It was an LS-1....


And about you running around town beating people at only half throttle....you must not have alot of fast street cars around your area. An average street car runs in the 14 - 13 second range. The faster street cars run in the 11-12 second range. Anything faster than that has quite abit of work done to it and plenty of $$$ thrown at it. Now your "stock" LT-1 is no where near 300 RWHP and it probably runs in the low 14s or high 13s. That is respectable but not impressive by any means. If you do ALL bolt ons then you can expect to run in the 12s. It just depends on how well your can can hook the launch! Don't down play any "mod" because they all add up in the end! If your not going to add a power adder or open up the engine then you have to do ALL the boltons to get the max increase and this can get expensive real fast !

You will enjoy your ride more too.

Actually, he has a different car than what is in his sig.. the car in his sig is an RS.. meaning its a v6 car.. his new ride is a 01-02 LS1...

The average car on the street does not go in the 14 -13 second range.. the average car on the street is at best a 15 sec car..

I dont really see "an 01 SS (i think might be an 02) has the SLP lid, SLP longtubes, y-pipe, offbrand muffler and thats it, he put down 357 rwhp".. so I thought I would think about it a tad..

now.. lets say the said SS put down stock what I do.. 320rwhp and 337rwtq.. bone stock.. but the SS has a catback from the factory.. so lets give him a tad more.. so how about a realisitc 324rwhp with perhaps a 344rwtq... now how about a lid? lets go to 329rwhp and 346rwtq... ok.. so now the headers.. LTs at that.. lets guesstimate a 343rwhp with 358rwtq.. now, I am one that believes in the power of a good Y pipe.. having had one on my LT1 I have seen first hand what it does.. so we add the y-pipe, remove the SLP muffler and put on some other one... 357? ok.. given that variance from dyno to dyno? ya.. thats not too hard to fanthom..

so ya.. its doable..

 

OK then. About the street car times....everyone has their opinion on this because there is nothing set in stone. But I feel anything that is slower than 14.9 seconds in the standing 1/4 mile is just a vehicle...not a performance street car.

Y-pipes are dyno proven to do next to jack squat on an LS1. The stock y-pipe flows well....it just doesn't look good with the ugly pancake section. The restriction is in the exhaust manifolds and catback, not the y-pipe.

 

You forgot the "Cats" that are attached to the stock y-pipe. With a off road y-pipe you will see a significant difference in power. That is dyno proven...

i thought with hi flow cats the gain when compared to an ory is 5rwhp

 

Your right, there will probably not be a "seat of the pants" feel with off road pipe compared to high flow cats. I was just comparing a off road y-pipe to the stock pipe and cats set up.

my bad, my bad

 

Just a question abuot times. My car dynoed 397 ran a 7.47 at denton dragway in texas. Then sprayed on the street burnt a piston, replaced them with forged and shave the heads another 30 thousandths for a total of 60 thousandths

 

7.47 was with a 2.1 60 foot. I got drag radials now too i need an idea what I might run with the new pistons, DRs, shaved heads??? Its an automatic as well

 

dunno.. try making your own post asking the same question. You may get more replies that way.

I personally cant stand 1/8th mile so I dont really look into that.

I prefer 1/4 mile everytime..
