How do you figure a Magnum has him by 30 HP? LS1's have an average of 350 HP.

 

I actually think it is.

It could have....the trans can be shifted manually....

While it is well known that GM gave the fbody a conservative rating it is either 305 or 310 depending on the year. The SS/WS6 gets you 325 which is a joke since SOME SS's only came with a hood and spolier and even the "performance" SS/WS6 only is rated at 345. Since the original poster did not specify that he had an SS or WS6 I assumed he has either a TA or Z28 which was 305 or 310 HP for 1998. I'm going by advertised HP not actual flywheel HP as for all we know Chrysler may have been conservative with their ratings as well. Trying to compare apples to apples.

 

 

has anyone thrown out the possibility that the magnum wasn't stock? it may have been blown or had full bolt-ons or gears or something. then he would have lost to a completely worthy car

 

That doesnt make sense though, just because they were advertised to have 305 or 310 doenst mean they do, saying he had 30 HP on him is just false. Its like me pulling up to a guy and saying, "Dude, I have a 98 base model TA (which I do), it has 310 HP." Don't think he's buyin it. (My car put down 316/341 with a lid and cutout thru an auto, 98's arent any worse than 99+) It being a well known fact that LS1'S were/are underated, and saying Chrysler MAY have underated theirs is like comparing apples to oranges.

DISCLAIMER: None of what I said was meant to be taken in a 'rude' light, I'm not saying it with anger or my nose in the air.

 

Saying that his car has 350 HP is not what it is rated at and without a dyno to back it up all we should really go by is the advertised GM HP rating. This disgreement is not worth continuing. You feel you can say his car has 350HP, with no documentation to back this claim up. I say 305HP based on advertised HP of a 98. If he ever has it dynoed then we can see who is closer but until then let's leave this be please.

I agree he should have beaten a stock 340HP Hemi due to the advantage he has in weight. I do not believe that with his mods he SHOULD neccessarily have beaten the SRT with 425HP.

I try to be objective about this sort of stuff but we always seem to get some folks here who think the 4th gen fbody is faster than anything else on the road just because they own one. I am not refering to you 'TRUST' as you make a decent argument even though I don't agree with you. But there are others here who think that way I believe. Lets get real folks, the fbody is a hell of a fast car but so are a lot of new cars coming out today. Maybe when the fbody was new it was the king of speed (aside from the vette) from American car makers but I do not think it can hold that title any longer with all the new power coming out. Hell, even my Envoy has 295 HP and that was not even built to be fast! I waxed some as*hole in a Honda with a wing, fart cans and stickers all over it the other day and he was like "WTF!" Rolled up next to me and says "what you got in there?" and I said "6 cylinder STOCK 4.2"

I am not angry,upset or trying to be rude either. I just don't think this debate is worth continuing. We have both made our points and we need to agree to disagree on this one 'TRUST'.

 

I agree Mike. I have both (see sig) and the SRT is faster, plain and simple....even been a pig at aprox 4120lbs!!!! Still the TA is faster than aprox 90% of what i found in the street everyday. I say to each its own! DCX is on the edge of muscle performance, Gm could if they had the cojones to jump in time. Sometimes they tend to think too much and watch the train pass by, IMO....

 

Couldn't have said it better

 

2005 Dodge Magnum SRT8 5.1(0-60) 13.6 (1/4)
2000 Pontiac Firebird Trans Am (WS6) 4.9 (0-60)13.4 (1/4)

and the 01 has more power

 

Nice try!...now go and search REAL numbers around tracks everywhere...some SRT8 have been hitting low 13's to high 12's...stock. In the REAL world both cars are very close...the HEMI as an engine is way more powerful than the LS1, stock of course...the difference is the weight of those cars...too damn heavy, IMO

 

put a stall, gears and long tube headers and it will feel like a whole new car

 

i dont know the weight difference but i did see 2 srt8 300m's at my local track running low 13's bones stock, i mean like 13.02's, i was told one went high 12's once but i didnt see that run. so they run good

 

He all ready has 3.42's.

I say you definatelty need a 3500 stall torque converter, tranny cooler and LT headers. Top that off with a dyno tune and your car will be alot faster, alot more fun to drive and in little fear of losing to 95% of the vehicles you'll see next to you on the street.

 

Tune UP! Plugs,wires,air filter,fuel filter.

 

Exactly! My precious heavy pig is aprox 4120lbs!! But at WOT sounds soooo nice!!

 

You really need to do some research. ALL LS1's are 345 HP. Let me say that again. ALL LS1's are 345 HP. How can I say this without a dyno sheet? Because all LS1 motors came from GM with 345 HP. They rated the corvette correctly. Then they underrated the SS/WS6 to not step on the toes of Corvette buyers. Then they underrated the Z28/TA even more so they could sell Ram Air hoods.

Do a search. Everything I stated is a well known fact. Not gossip or hearsay, but fact.

This is why LS1's dyno 280-315 rwhp in stock trim and run solid 13's in the quarter (sometimes even high 12's).

 

OK, I'll buy that. Now, are you sure all Hemi's are only 340? That was my argument that you need to go by advertised HP cause you do not know how fudged the "advertised" number are. You use the dyno as your proof. Let's see the dyno numbers for the Hemi. I think you need to do the research.

In any case I felt he should have beaten a Hemi so this argument is BS. I'm just not naive enough to think the LS1 can beat everything else on the road just because I own one and some here (not saying you) have that mentality.

 

I don't need to do any research on hemis because I don't care. I never started what they dyno, what they run or whether or not you should have beaten one. I merely pointed out a mistake you were making on LS1 F-body numbers in relation to real vs advertised.

The bottom line for GM was how to market our cars without pissing off the Vette guys and without making two seperate LS1 motors. It was more cost effective to throw the same engine (with the same heads, cam, ect) in all F-bodies/C5 vettes then too create another motor. So in the end it was cheaper to lie then to actually make a more powerful engine for the base vette
