2007 Ford Mustang Shelby GT vs 2008 Subaru Impreza WRX STI

[ray_sir_6]

05BLKSTANG - The one stock 05 Mustang GT that came in ran 243whp. The LS1 is the stronger motor, which can be due to it's larger displacement, but it makes more whp and lots more torque than the 4.6 can. Even with mods (I/H/E, tuned) the 4.6 has a hard time equalling the stock LS1. Plus the Stang is a fat pig! ...shaped like a brick, so aero sucks, too. I haven't run a 05+ GT yet, but my run in with a 310whp 98 GT could only pull me by 1 1/2 cars from 20 to 110. We ran 3 times, all with the same results. He would get the jump, I would fall back 1 car, hit boost, and he would BARELY pull till we shut down. I was in my 91 Miata 1.6T with 146whp....gotta love the weight advantage!!!

Just read your post and would like to add something;
- In 2005 Ford sent out memos, dont believe it was an actual re-call on the GT models. The had installed the wrong program to their new Spanish Oak computer and thats wht the car dyno'd 243RWHP. Please call any tuner shop and say your ordering an intake + hand held computer tuner and the first question the will ask is, on your on board computer there is a white sticker that either reads CPH1 or CPH2. If you have the CPH1 than you can bring it in for a re-tune. I was fortunate to get the CPH2 program.
Next time an 05 comes in check the computer, have you dyno'd any 06 or greater?
- My car right now dyno's at 308 RWHP. There is no way that there was 65RWHP left on the table. From what I've seen the are arounf 270 RWHP, with the tune, intake, pulley, header, axle back 38 RWHP gain sounds more right.
- The Stang weighs 3550 fully loaded which is less than 200 lb heavier than the regular Vette, the 05 GTO weighed in at 3770 Ibs. To get a RW drive car that light for the money is exceptional. The 08 Challenger is going to be around 4000lbs and Camaro dont know but the GTO should give you an idea.
- Yes you could say the front looks like a brick, does anyone know the cd (coefficient of drag) of the car? The Challenger also looks like a brick but is estimated to hit 170+ mph.
- The 98 Stang was a very poor year (dont mean to offend anyone) 01 to 04 fixed their problems and the 05+ althou still in the modular family, is a totally different engine, using variable valve timing, added valve, a good manifold (which is the achilles heal of the 01 to 04) and dont think comparing the 98 to 05 is a fair comparison. It's like comparing the TPI to the LS1 - they're both 350's but have gone two changes since.
- I dont doubt the race in the Miata below thou.

The new GT's wake the hell up after a good dyno tune, but I guess that would just be messing w/ it and not adding real HP. Seen that in person, a 25 rwhp gain from "messing" w/ a/f ratios and timing. The new stang GT computers are almost as bad as the ones in the damn dodge srt8 chargers. blah. glad people out there cracked the program for them now.





oh

and no, I don't work at a shop w/ a dyno, I just utilize one of the best tuners for late model GM's in the nation. Guess since that shop has the fastest Trailblazer SS, won the LS1 shootout, placed very high in the LSX shootout, laid down the law at rockingham nationals last summer and has the best output from a H/C/I/E LS1 so far ( 498 rwhp and 471 rwtq ) on stock cubes.....they must just be messing w/ their own and their high roller customers cars too. I hate it that every GM car that dynos is "messed" with to please the customer and give them bragging rights.

Well, we don't dyno alot of domestics, and the ones that roll thru are normally LS1 from the rear turbo shop. The GT guy was really dissappointed in his whp, but we don't adjust the dyno graph to appease egos.

The 98 GT I raced had swapped heads and intake manifold from a Mach1 (same intake as the 05+ 4.6l I believe) plus header, X-pipe, intake, pulleys, and some other crap that I didn't care to remember. The comparision was more for the power-to-weight, since the new 05+ GT weighs more than the previous generations.

MX-5's are RWD and weigh 2800lbs. Of course, they only come with 180hp, but that is easy to fix. A turbo kit (there are some in development, maybe even one being sold by now) is all you would need to make 250whp, and use the weight advantage to beat-up C5 Vettes, Stangs, and Camaros/Firebirds. Or if you had gotten the MS Miata (2004), it comes with a turbo, and costs about $1800 to get 250-300whp, in a 2600lbs car (with you in it). My Miata weighs 2436lbs with 1/2 tank of gas and my fat 236lbs ass in it. 4.3 stock rear. With a good setup, a 130whp (IRTBs/tune/header/exhaust) ran the 1/4 in 13.9. I ran a 14.9@93mph in mine with a 2.4 60ft (launch at idle, hard launches destroy stock diffs!).

^ Miatas are fun lil rides in stock trim, they are like a oversized go-kart. There was a video floating around where some crazy dude put a H/C LS1 in a miata, he must have a death wish.

Tuning a car is not what I was referring to. Let me do this so YOU can understand.

One: Take your car to shop with dyno, have them tie it down and rip off 3 pulls.

Two: They open up your logfile in the Dyno****.exe program that came with the dyno.

Three: They adjust the temp input to a higher temperature, thus causing the formula to add FAKE WHP to compensate for temp variations.

Four: They select a correction factor that adjusts the formula to determine whp to the one that shows the most.

Five: They print out your dyno graph showing more whp than it had before they made the changes.

Can you understand that? It is FAKE HORSEPOWER cause they manipulated the formula in the program.

Where in there did I say "Dyno-TUNING"? I didn't. Dyno-tuning compares the before/baseline to the after/tuned output. This reflects ACTUAL increases.

So you know a shop that has this record and that record....let me pat you on the back. Way to know people!!! Next time you see them ask them to show you how "correction factors" and atmospheric conditions can affect dyno readouts. If they like you, they might let you watch them play with the graphs on their program and you'll get to see how it changes the whp.

Miata is a nice fun car to drive (never driven it but was a passenger) had no competition until the Sky & Solstice came out. Out of all three, even thou the Miata is the fastest I'd go for the Sky, my sister is looking at buying a Solstice thou.
Pulling off a 14.9 sec run in that thing is good and your mph is pretty respectable.
When i picked up my 05 Stang I took it to the track with just over 3000mi.
Problem was, it was stick my last car was automatic, so my driving skills were ok i guess.
My friends those *******s (lol) bet me I couldn't put it in the 13's
The 2nd last run i did was 13.997 at 100.1 mph hitting 2.4+ shorts all day
Best mph on that day for me was 102.48.
I know that car had more in it, I just couldn't get it out of her.
Sad part of that day, which I didn't find out until I joined this forum was, one of my friends, friends came along and taped my ass without me knowing. I dont give a sh*t about that, but then he posted it on this forum to make me look like a sh*t driver and trash talk my ride.
Can you believe that. Totally unprovoked.

Yup. The previous owner of my Miata was planning on doing the same thing.

Miata + LS1 + SC = HOLD THE **** ON!!!!

Putting a V8 in the front throws the balance off though. Mine is a track car (road course), so ultimate HP is not in my plans. 250whp will be plenty. It already got all in the ass of some GT3s at the last track meet. I should have gotten a picture when the Ruf RGT waved it by! I wasn't driving, I have a pro who does that for me.

I prefer the styling on the Opel GT...err..Saturn Sky. If I was to get a little roadster today, it would be the Sky Redline.

I don't normally goto the drag strip, not my thing. But everyone was saying my POS wouldn't break the 15s, so I made 3 passes, third one was the 14.9 and I went home. There were a few Mach1s out there running DRs that were just cracking the 13s....13.8-13.9 the runs that I saw. I ended up lining up with one, and he ripped it out of the hole, and I actually started gaining after the 1/8th.

RT .911
60" 2.359
330" 6.385
1/8th 9.704
mph 75.40
1000" 12.540
1/4 14.946
mph 94.10

So my 60ft times were 2.3. Whoops.

[UKunt]

those times are not with a turbo kit tho are they?^

[Double]

Ordering my tuner today m, can't wait!!!!!

Yes, with the kit. 146whp. Stock it made 98whp and ran 10.6 in the 1/8th launching the hell out of it.

[01mmmz28]

^ If the weight thing scares people off from doing a V8 swap, would a rotary swap work on those? Or even be feasable?

ahh well didnt think tat 14.9 was that great for the power u have. as ive had a friend with fwd and 99whp get 14.5@96mph..but i guess its abit lighter then your mazda..as he was getting 2.3 60f times.

[05BLKSTANG]

Well your mph is a little higher
But I'm the opposite to you. I Haven't done any coarses but know that quater mile is more fun for me. Dont like the thought of being on a track and having someone hit me. The last time i was at the track (1/4 mi) 1/4 mi I saw someone lick the wall, since then when, I wont line up with any car that can do a mid 11 sec pass or faster. At the eighth mile Im at almost 84mph (this year hope to improve it) having someone come into your lane whose 6- 7 cars ahead of you before the 1/8 is scary.

Besides dropping a V8, have you considered a V6? Im sure you can pick up one those alot cheaper than the V8.
