I like to pick on ls1s. I see a lot of those slugs at the local track and half can't even break into the 13s. A lot of fbody drivers are no driving fucksticks. I don't worry about them anymore. I like to race single turbo supras on the highway.

It's a five speed dude but you are right about one thing when it does happen I think it's pretty funny....

Ok 5spd, still pretty funny though. Makes me think of the ricers that do their flyby's after I'm 4 cars ahead and already let off. I'm sure they go and tell their friends they just smoked an LS1. "ya, I got that fireturd on the top end."

All of those mods, Kenny, are not doing too much (the larger TB, the larger MAF, etc. are flowing WAY MORE than your E7 heads can make use of. you might be getting 10 rwhp between the two.) See, the stock MAF is dot so bad on these cars, neither is the TB (which is something like 60mm i think). THe long tubes and cold air (depending on whether its fender well or not) and the cat-less h-pipe are doing some good, but the main plug in the hose are those E7 heads which flow only about 155 cfm intake side. That is less than a stock LS1 exhaust port, unless i am mistaken. As to what your combo makes EXACTLY, i dont know, i would look for a combo like yours online that was dynoed.

I'll take my lightly modded 306. Havent been outrun by a f body yet myself, even when the motor was in my old GT street car. Seen alot of nice F bodies and such, but most dont do the F body justice, or the LS 1 either for that matter.

[/QUOTE Haven't told me your 60 ft yet but i bet when your car was stock it ran maybe a 13.50 w/ 2.0 2.1 60ft, **** the street its stupid to race there any way but if you were stock and we raced at the track you would be looking at some tail lights my friend.I know ,I know now you are going to come back and say that your unbeatable ls1 would have gotten me up top. Remember we are talking stock ls1, so don't come back and say that I do ricer flyby's because at the track there are no excuses ,and you know that even if a fox body beat you at the track or on the street you would never admit it. I think it's called denial ? I have respect for ls1 sbut they are not unbeatable.

If you can seriously outrun LS1's and LT1's with those mods I will sell my car right now and go buy another mustang right now. You must have a freak of nature. I mean **** the only mods doing you any good besides that weak *** cam is your exhaust and gears. You may have a different MAF but with that 48mm TB it is not doing you any good and may even be hurting. That cam is way too small, and with the stock heads you are probably seening minimal if any gains at all. I used to be a mustang freak before I owned my LT1, and I can guarandamntee you that with those mods, you could not come close to a well driven STOCK LS1. **** even a well driven LT1 would be a challenge. I am not doubting your times at all because where you are located and where I am the same car can run completely different times. But I'm sure that LS1's around there run better times too. But **** I guess GM was stupid for giving those cars another 48 CI (44 on the LS1) and almost 100 RWHP, cause ****, any guy with a few mods on his Foxbody could beat an fbody.

I used to be an LT1 freak before I became a mustang guy. Want to know what changed my mind? My friends 89(?) LX with gears, CAI,pullys, and exhaust held almost dead even with my 95 LT1 A4. I figured, hell, no way I can afford to mod this LT1, but mods for the 5.0 are CHEAP. So....ALso, Kenny, your mph was 92.XX in the 1/4 and your time was a 14.4 You have a decent ET with CRAPPY mph. What that is saying is that your hp is not 260 rwhp. Rather, it is a testamony to the awesome traction that the fox chassy can get and your launching skills/low end/gears/tires. 15mph to any speed and the LS1 would murder you. I love the fox 5.0 and drive one, but i give credit where credit is due, even with all my mods I am hoping to only be the rough equivalent of an LS1 from a roll. (I did kill an S2000 55-95 mph all in 4th gear though not by much, but at 55mph even with 4.10's 4th gear is slow.) Also, my car wont launch worth crap, I cant get the legendary fox traction Dunno why, tried slipping the clutch at 2K rpm and it just spun 245/60/15 tires btw, maybe i need radials, but it rains too much for that.

48mm TB????? what are you talking about? Stock TB is even 59mm, so where does 48 come in when his sig says 70mm? And you mention stock heads??? GT 40Ps are some pretty impressive heads. Maybe if you traveled to a NMRA race you would see the times these guys turn with a cobra intake and some GT40ps. I bet his car will run mid 12s and i know that will touch your average LS1

I am sorry Kenny, thought i read 92 somewhere. My fault. A mph of 101 is getting LS1 close, you may have more hp under the hood that originally thought. For comparison, my friends 98 A4 Z28 pulled 13.3 @ 105. He prolly had about 300ish rwhp, no? So 101 would POSSIBLY be indicative of mid 200's? I dont know, anyone???

4.6's run 101+mph with 230ish rwhp. He is lighter than a 4.6l also. There is no way he has mid 200rwhp with those mods. Like I stated before, he is most likely 215-220ish rwhp going by what other guys have dyno'd with similar mods.

A buddy of mine around town and I , took his white vert '93 5.0 to moroso and ran a 15.1 That was a convertible and automatic car. I wasnt impressed. From then on, ive been wanting a LS1 but id love to have a little notchback to play around with too.

Convertible and AOD kills it. Probably had 3.08 or 3.27 gears too. Conv are heavier than GTs. So watching them run would steer you from a mustang. Most AODs run like crap also unless they are built aods.

Of course they werent stock tires the subject changed there. Do you get out your rule book every time you get in a race? The best 60' Ive managed on the Michelins was 1.91. I saw a 1.85 once from my buddies Notch when he had mufflers only but thats the extent of that.

Stock suspension, stock 3.08 gear with ET Streets with the 1.6, they sell ET streets for F-bodies too. I hardly think a tire change shouldnt be allowed.

I told you for the sake of comparing what my G-Tech times were for my stock 5.0L vs my stock LS1. While the G-Techs not accurate time wise if you do the test in like conditions you are going to get comparable results.
