2002xREDxZ28

Alright I have a 2002 Z28 6speed with Pacesetter longtubes, TSP catted Y pipe, SLP intake kit(lid, smooth bellow, etc.). Initially, I was underthe impression that the new 5.0's were stock and bolt on LS1 killers. However, my experience with 6 different stangs is the opposite. Stock ones I put 1-3 car lengths on depending on how long we run. I ran 2 that had "exhaust", I'm assuming cat-back. Pretty much the same outcomes. I ran one with longtube headers and we ran pretty even up to 120 when I pulled a little. So if anyone could shed some light on the situation, I thought my car would be getting beat by these stangs but apparently not. the last 5.0 I beat, said he raced a Z28 before and he handed him his ***.

I've seen them at the track trapping 110-112 pretty often (stock), with the occasional slow ones lacking driver mod. There are plenty of bolton LS1 F-bodies that run quicker. Getting out to a track could give you a good idea of where you're at.

A bolt on fbody and stock 5.0 is usually a drivers race with edge to fbody. Cause of weight. Mod for mod a 5.0 will hurt a fbody feelings. Plain and simple. Stock 5.0 have trapped 114. Bone stock.

it takes very little to run with or beat a stock-stockish 5.0 gt.

I agree with these guys, and the driver mod always plays a major roll too

Sounds about right to me. My light bolt on A4 99 Z28 whoops the **** out of stock 5.0's. I even ran an A6 5.0 with cat-back/X pipe and tune, and beat it by a little more than a car length from a roll. They're not that fast.

Only on LS1tech
Exhaust and lid only isn't beating too many 5.0s, you must have found the turds. LS1 f-body guys, from my experience, who lose to the new 5.0s say they get pulled up top...

The new 5.0's are over rated

Yep, but as you said on here stock LS1's beat lambo's and anything for that matter. I had stock 5.0/bolt on/blown/ And never had a Fbody line up with me and beat me. When was full bolt ons a full bolt on WS6 got murdered. He is a memeber here. And I was spinning and short shifting. A auto from a roll isn't really impressive less he has a stall and his trans tune is perfect. A manual is all on driver. People here will have you believing all cammed Fbody run 10's but I have seen way to many run high 11's to mid 12's.

My buddies stripper model 2012 GT with nothing but a catback and maybe 50lbs in weight reduction went 12.4 at 116...

My buddies full weight GT/CS with mufflers, x pipe, AED tune, cai, driveshaft, and wheels went 11.8 at 117. 3750lbs on the scale that day.

Stockish f bodies should puppy kick those cars....

big hammer

as long as we're going to extremes, didn't notches bolt on ls1 go high 11's @ 116 as well? looks like a good race for your best examples.

So then hes a race for my buddies stripper model catback only GT on a drag radial (only cut a 2.0 60 on that pass). Whats extreme about that car? lmao. Base model car with a good driver. The other car is the heaviest 5.0 on the market and still went that time with very little work. The stripper model with those parts would run quite a bit harder.

and bolt on manual 5.0's have went 10.9@124 and bolt on auto have went 10.7 and 10.8@125. Even 10.9 now in 2500 DA and 80* heat. So nope bolt on fbody get raped.

I drove my manual with bolt ons in 100* heat and 4000 DA ro 11.7@120 and buddy drove it to 11.4@122 in 70* weather bot on drag radials.

Bone stock with just tire went 12.1@114.

Equal drivers stock for stock and mod for mod a 5.0 will rape a fbody.

and wasn't notches car on stock manifolds? this isn't speculation, it's simple numbers. stock, sure the 5.0 is faster but ls1 cars also wake up ridiculously easy with simple mods. it doesn't take much to run past a stock-stockish GT. the trouble is these cars are getting old and finding one that isn't tired is getting more and more rare.

big hammer

uhhh bolt on ls1's have gone into the mid 10's at 124+ as well.

I dont understand why people cling to the past so much. Theres nothing bad or wrong with a 4th gen f body. Id love to have one and build one. But i already have my car. IDK why people just cant accept that an ls1 f body is not as fast as a 5.0. Its not meant to be a dig to anyone. But it is what it is. Aftermarket changes everything. But if you were to do the same mods from bone stock to modded... the 5.0 is always faster.

big hammer

it's neat how you can't comprehend numbers.

and your point with the manifolds? Pretty sure a catback only 5.0 means it has stock manifolds, stock cats, stock tune, stock air intake, etc etc etc...

Take a 100 percent stock f body. Put JUST a catback on it... and remove the spare/jack. Run it down the track. If you can find me a SINGLE f body to ever run 12.4 at 116 with a 2.0 60 ft.... i will stop talking.


But you wont....ever....

poor evan and his cherry picking.
