That's, in my opinion, a horrible setup. Congrats on peak numbers, but the car isn't rocking in it's true powerband until 5000 rpms... and they're out of the throttle at 6800.

Even going by gear ratio, when he goes from 3rd to 4th (roughly 90 mph for most cars) he's dropping back to 400 whp and has to wait for it to come back in.

Very cool that they broke through the barrier of people stopping around 500 whp, by a long shot at that, but a 37R is a BIG turbo... and for them to really utilize that setup they should be revving a lot higher.

I wonder why they aren't? Oliver rods, built head... DSM 2.3 and 2.4 strokers go 8500 rpms with similar rod/stroke, so I wonder why they're not going higher?

The owner posted that the 6800 rev limited is being used right now to tune the driveability of the car. With the built lower end and an aem ems to run things it will/is going to rev higher.

Real horrible... ONLY 400whp at the start of each gear ;)

True point, until you think about how 400 feels in comparison to 700.

However, the point is moot if they're bringing the revs up, since the gears will then drop the car right back in it's powerband. Now your only downside is that it's still FWD!! :D

Once again, congrats to them for busting the barrier wide open. Now let's see how it runs!

That doesnt make a lot of sense to me. I would think you can tune the "drivability" on the street no matter where the rev limiter is.

400 HP would allow for some traction compared to 700 HP LOL...

Definitely good to see them top 700... how much has Cox gotten out of these, 1400? Of course with different intake, huge turbo, L/A I/C, etc, etc...

A 400whp FWD car will just obliterate the tires at anything less than 100 mph (been there) so it is partly for safety.

Also, for general "drivability" purposes you should not see too much over 6k rpm regularly.

Don't ask me. The owner stated that the pulls were in 4th and they were observing a 6800 rev limit right now that would be raised as tuning progressed.

I can't believe I just ran across this! This is a buddy of mine here in Texas I haven't talked to since his last setup. Even before all of this, Blueball and I was in a 98 Viper GTS racing him from a 60 MPH roll. At 150 MPH his back bumber was at the front bumber of the Viper and his car was still pulling just as hard.

true, alot of those guys are arrogant pricks who think their SVT can do no wrong but you have to admit it is still a neon. its basically a 4 door economy car with a turbo on it. granted they are nicely equiped out of the factory and pretty quick. i have owned Mustangs in the past and they are great cars and i would love to own another if they werent so expensive. most of the guys on SVTP have fast --- cars. 03/04 Cobras, Lightnings and the like. i wouldnt wanna lump all of them together in one group becase i know there are some cool mustang guys.

So what if its just a Neon, thats the same mentality as saying, its just a Civic, its just a Spirit, its just a Van, etc. Who cares, it makes power, looks good, just STFU and enjoy it.

When the Mustang guys say, "it's still a Neon" just reply with "Mustang, it's still a Fairmont". They usually don't know what to say after that.

I dont think 4 1000cc injectors will support that much HP(it looks tame, I think its kinda like the DCR Fix/modifier just something to get hype and more business.

AMS', while a great company and they put out a lot of great cars/products... their dyno numbers never seem to line up with real world numbers, like inj. duty cycles.

As stated above, 1000cc injectors would be straining pretty hard to keep up at that level.

Welcome to several weeks ago Strat.:evil: My defensive side says it depended which one of us took off first. Could have some proof if "SOMEONE" didnt record a run against some lame TA over it.:eyebrows:
1600cc injectors are on the way along with a different intake. 400hp when shifting should help in the trying to get a bite on traction. There were also issues when going much over 6000 rpm's previously. Suppossedly gone now. There will be another dyno run to compare current numbers. As for the Mustang guys talkin down,theres quite a few of them that got educated on the big end.:rockon:

You're still missing a 100 WHP difference in claimed power numbers there... which is not going to happen in a 10% difference by a long shot- not to mention spray patterns and overall consistency of the injector become sporradic above 85% DC's...

as of right now i believe 1000cc is the largest used by any srt, and at 90% the injectors would work, there is just a risk of them falling off and the engine going lean correct??

That video doesnt make a lot of sense.

a 772whp neon barely beating a 490whp car that weighs 4000lb......

Yeah none of that video makes sense........
if its not the same car then why is it posted here.

Why are they pretending his neon has a 50 trim when its got a MUCH bigger turbo.

I believe that was when it was on a smaller turbo and just had a better supporting setup than the other 50 trim car... I think they were trying to show that the car was already strong, so the Mustang guys that are complaining and dogging on it already should be worried. That was my take.

Miles- read my post above a couple about the injectors.

gotcha, i see now, trying to catch up here, haha

and that car was on an untuned 50 trim in that video, so i'll call it 300 whp at best, his name on srtforums is 4u2nv.

and i know this because that video is too old for him to even have an AMS turbo kit. or a 37r for that matter. Look at the date of the one comment, June 30, 2005, the AMS kit didnt come out till this year and no one had the 37r till a few months back.

Don't get too offended by the post over SVT forum. If you look at a lot of auto forums people get defensive over post suggesting that a car not pertaining to the forum is better in someway or another. The people who log into SVTperformance have been respectful over my turbododge post and another guys dodge spirit RT post. You just have to post it in the right maner and they will respect that. As a owner of a 03 Mustang Cobra(Ford Fairmont,LOL). I give respect to anything that makes 772whp.

Even w/"serious"mods it wont launch as hard as RWD. Sticky tires usually handle like crap on the street(slicks),springs only help a little. Thats why a 60 to 160mph run is needed. Maybe higher now that rev limit is higher. From a roll helps a little to even the field between the FWD and RWD guys. Texas Mile anyone?

AMS has made a nice kit. It also made me 792hp 650tq.

Damn, looks like a nice kit, and your ride has to be flyin'! Ever run it down the strip? What else do you have done to the motor?

Nope I have not got the car back yet. I will be picking it up within the next two weeks though. Here is a ViD if you havent seen it yet. This is when the tuning first began though. Link to ViD (http://media.ams-evo8.com/videos/srt4/Neon772.wmv)

I belive he is running the AEM engine manigment which has TC that should help a lot.

Only if it is setup correctly, and very very very few people know how to use it on AEM EMS. Although some trial and error will get you moving in the right direction.

A better function in my opinion is vehicle speed based boost control when using the AEM boost control solenoid. That way peak torque can be held back by slightly cracking the wastegate before the torque peak hits in the first couple of gears.

Still runs stock Mopar oil filter:p

01-04-2007, 06:26 PM

The thing is... the Neon will never be able to put the power down effectively without some serious chassis modification.
what he said. what good is 772hp if you cant get it to the ground? i mean, an SRT4 is a great car from a roll but bring it to the strip and its like night and day. ah, the downfalls of FWD.

turboweasel

01-04-2007, 10:00 PM

With the right tire and some good traction bars and since he is on an ems it could be a good 1/4 car by limiting boost tell it is moving enough to put it down.
With the ems you can limit boost for each gear so you can set it up like the stock pcm. So there will be traction and then full boost in 3 and 4 witch since it is a turbo car its going to be all top end any way.
