Original - 240 HP (219 rwhp) ~8.75% loss of HP

240 HP @ 6psi = 337.9858464888404 HP (308.412084921066865 HP with 8.75% loss)

240 HP @ 8psi = 370.6477953184539 HP (338.21611322808918375 HP with 8.75% loss)

1/4 Mile based on weight and HP (assuming weight is 3700 lbs.)

240 HP @ 6psi w/out loss = 12.933914526018586@105.71980271464603 MPH
240 HP @ 6psi w/ loss = 13.334774696619257 @ 102.54173190983471 MPH

240 HP @ 8psi w/out loss = 12.542257058673474@109.02111841769242 MPH
240 HP @ 8psi w/ loss = 12.930978608838613@105.7438058929392 MPH

Well, that was fun and not probably real accurate, but still fun :D This is assuming without the exhaust system in place, but none of this is really given because you don't know how the conditions are going to be. Anyway, I'm done rambling and cramming up your thread with figures :)
I have searched and searched for an accurate calculator like that and have yet to find one.

Even the G-Tech I used at one time was off significantly (1/2 second).

What calculator did you use, I'd like to try mine.

Yeah, guys on bikes are... how do we put this... crazy, yep thats it :D You screw up at 120+ MPH and results will not be in your favor. It is funny how low 11s are slow for a bike ;) It must still be fun though, I just don't want to take the risk... what do you run?

No thanks, I don't like to lose. :D

I like to compare apples to apples. ;)

http://www.stangnet.com/calcs/index.html ... it seemed pretty accurate with 240 HP weighing 3700 lbs resulting very close to the best ET that it has run.

Well, according to the calculator I should indeed have about 305 hp, but that would have to be at the flywheel, not the rear wheels. There's no way I'm getting that at the rear wheels.

Running a blower at 4.5 PSI would put me at 13.1 in the quarter, very respectable.

A 125 shot of nitrous would put me at 12.7, according to the calculator.

Interesting numbers, hmmm.....

Per the Cobra article:
With temperatures in the 90’s, both vehicles combated the ruthless heat of the day with some impressive driving. The 5-speed MACH1 produced a best run with street tires with a 13.41 second pass @104 MPH and the automatic MACH1 put out a best run at 14.03 seconds @99 MPH.
And that was in 90 degree heat, mind you.

Big difference between the manual and auto, must have very different gearing, or a real inefficient auto.

BTW, this is now officially a "car" thread, not necessarily my race story thread. :D

Were the numbers you got close(er) to what you are already getting with the numbers you know, using your ET, MPH, HP... etc... just kind of wondering if it is pretty accurate for everyone else or some strange occurance with me.

My own experience with the B-bodies (Caprice/Impala/Fleetwood), and based upon known dyno runs on various B-bodies with known mods, also with track times, I calculated my HP to be right about 300, with a race weight of 4500 pounds. The calculations showed 305 HP with an ET of 14.2 at that weight, so it seems to be accurate. The big question is how much my car weighs. I've thought about running up onto a truck scale off the interstate, but I don't know if the scales will go that low or if they'd even let me do it. I'm not paying anybody to weigh my car right now.

So basically all I have to go on is my ET and trap speed, with HP and weight unconfirmed. Hard to say if it's truly accurate, but I would imagine it's at least in the ballpark.

My car stock: 260 HP.

My HP mods (est. hp addition):

Intake w/cold air box (5)

Punched out 0.040 over: (7)

2.5" cat-back Dynomax Ultraflow exhaust (5)

Hooker "tuned" headers (10-15)

agressive (93-octane only) PCM programming (10-20)

LT4 knock module (to eliminate "false" knock ignition timing retard that sometimes goes with headers) (0-5, I figure 0 until I get a good scanner hooked up to the PCM)

LOL all this talk about racing...

hehe then there was me playing around with an old 5.0 mustang on the way home :D ...he was alittle surprised when i took that curve on the road doing 120km/h

my car is still slow though....need that turbo!!

i'm just $2000 away from getting it!

11 flat is what I can run, my bikes not one of the fastest, its no Hayabusa :) Your right about us being crazy, but theres no better thrill of riding a rocket.

Ouch, $38,000 for that. I would rather save ~ $10,000 and buy the new Mach 1 Mustang coming out or just buy the 2003 Cobra for that (some dealers are selling them for $40,000+ though), hardly anyone is selling the Cobra for the MSRP ($34,750) a lot are raising it a few grand. I still wish they would make the old body styles (like muscle cars) again with todays saftey technology, ain't going to happen, but it would be nice ;) Of course you wouldn't get near the same engine, but you could get a little dirty and pull something off if you wanted.

Heh :)

The mustang doesn't even compare in style or performance though ;)

You're very funny :rotfl: :rotfl: :rotfl:

And you're right, the new Cobra doesn't even compare, it tears that car apart. http://www.stangnet.com/2003cobramustan ... rview.html
With a few minor changes MM&FF got it to run 11.68 @ 119.36 mph and with 4.10s, full after market exhaust, and a chip they wonder if 10s are possible, and I'd say for sure they definitely are.

Americans and their cars, eh Tom. :rotfl:

Wait a while until the Aussie built Monaro hits the streets over there rebadged to Pontiac I think. 30,000 in the first year.
Days of thunder revisited.

Im sure they think we catch a ride to work on the back of a kangaroo.

Don't forget the value of our dollar, currently running at US$0.566c
That brings the price down to what you are used to seeing.

Well, Barbara is seriously considering the new GTO when it comes out, she'll keep her Impala SS as well:

Image


As far as the performance is concerned, I'm sure the LS1 that's slated to go in there will provide plenty of performance and will serve as a great platform for future mods.

To AAF Striker: Comparison to a Mach 1? We'll just have to see when both are in production.

Make a trip over to yer local gravel quarry. They have scales to weigh trucks with and without gravel(normal 1/4 ton trucks). You'd get a pretty good idea of yer weight that way. Dunno how accurate those things are, could be calibrated funny. Worth a shot I guess.

Interesting suggestion, I hadn't thought of that, thanks.

I'll have to investigate that once the dust settles.

Croc, I was going from the article that Tom gave which made it figure $38,000 American. Don't get me wrong it looks like a nice car, but for roughly the same (or cheaper) price I'd invest in something with more power and possibly/probably potential. There is a huge aftermarket for Mustangs, 5.0 and 4.6. Anyway, I am still interested in seeing it run. I personally just wouldn't want one ;)

No probs. I didn't read the article but was going on the figures and thought they were U.S. $$$$.
From reading the press release about building the new GTO a while ago, I believe these will be made in AU using a 5.7 litre V8 brought in from the U.S.

If you look at the body shape closely they are very similar, considering the GTO is an artist impression and the other is Tom's car. A few additions like the third h/lamp and badges.

I'm too old now to be a petrolhead. Now I go to work on a 50cc 2 stroke PGO Bolwell scooter. LOL
Used to be but back then it was racing and rallying that were my interests.
Wait till the release and you have taken one out for a testdrive. See what you think then about the car and price..

Croc.
