i could run 12's of GM promised to give me a new car! ide prob blwo mine up doing it thoe

full suspension setup,SLICKS, LSD, tranny/engine mounts, AXLES
REV IT UP kit, intake, exhaust, Header, NO cat, ported blower, Jbody Performance Cams,
Throttle body, Stage 3 clutch w/ lightweight flywheel, Short shifter, No back seat (for the track) and no spare tire w/ jack

and if all else fails the soon to be saturn motorsports ported & polished Head w/ all new valves springs etc! bump rev limited while im at it

12's can be easily done with stock internals and the blower. The only thing that would need to be changed to go much faster than mid to high 12's is the pistons at a certain point as they are the only component that is not forged. At 2900 pounds here is what should get you into the 12's(with good driving). 2.8 inch pulley, 44 lbs. injectors, MAF translator, Intake, Exhuast, Ported Blower, Solid Tranny Mount, Clutch, and a set of BFG's or MT DR's. I know this is a little bit of a repeat of the post above, but you don't quite need all that was listed. With around 285whp and 3150lbs with driver you will run 12's. The camaro runs 13.5-13.6 stock with 290whp and around 4100 with driver, along with poor stock tires. With a decent Driver 12's aren't far off, I am just waiting until tracks start to open again around here.

basically what i said bro i agree with ya fully just gotta know how to drive!

But you will need LSD or suspension for those who dont cus i spin all day on fresh tires 1st and 2nd gear gotta let off , then let on, until i grab

gforce477

The LSD might not be as important as you think for drag racing, however it does help quite a bit when getting on the gas out of a corner. I have a new Tranny Mount already on my car and it helps a lot more than I would have thought, I will be getting DR's soon and I think those two alone will be enough to put pretty good traction to the ground. With the new mount my wheelhop is no more, but I still spin quite a bit.

I have never had any issue with strait line traction with my SS/SC and I don't have an LSD.

The only time I get one wheel spin is when I put some body roll and turning into the equation and then it's pretty easy to get one wheel spin. So unless your going down the 1/4 and turning at the same time I think the LSD won't help much.

As for 12 seconds, you going to need to have more than bolt ons to get anywhere close to 12's.

I must be puttign down alot more power or something to the wheels then cus even with 3 peeps in my car taking off normal, then punching it as soon as i shift into second wheel spin!

We will be able to run high 12s with bolts ons. But thats about as far as its gonna go. If you want to get into low low 12s/ high 11s you will need to do some major upgrades. You will also need LSD. I make this assumption from all the SRT owners around here. Take 2 cars, one with lsd, one without. Install all the same mods. Once you get to the low 12s mark, this is what happens. Car without lsd runs a 12.3 while the car with lsd runs a 11.9.

I cannot beleive that the stock pistons will just go to hell once you hit 300 hp.
Thats just seems kind of stupid, for gm to put weak pistons in there "tuner car".
SRT's can handle 430+HP on stock internals....(my cuzin's has held 436HP for over a year now)
I hope they are not weak as you people claim. Any proof of pistons frying at 300 hp?

gforce477

Sorry Clownhair, I was referring to mine which was Convertible. It weighs in at 3928 according to stock specs, and it will stock lay down a high 13. As for the pistons who knows, according to GM performance department 300+ starts to push them, but of course they are being conservative. Still the are much weaker than the rods and crank, as the pistons are cast pieces. and pushing over 150/L can't be kind to them.

Before we trash each other, lets see some results after someone gets the Stage 2 installed.

Having been 12's in another car, I would say you would need the stage kits, some easy weight reduction, intake/exhaust, slicks, and a small shot of nitrous, with an excellent driver. With our gearing I don't see it happening too easily. There is a reason people have had trouble going 13's, let alone 12's.

Since our car is similar to an SRT-4, does anyone know what it takes for those to runs 12's?

RonSS

Sorry boys.

To run 12's, and by that I mean a 12.99 with a 9, you have to run 106 or so, and that is with a RWD car. 60ft in 1.8 or better.
In our FWD traction limited cars, better make that around 110, and hope you can get below 1.90 in 60ft.

A buddy has a 90 Grand Am, quad 4, tons of mods. More money spent than you spent on your SS/SC. He holds the record in the NHRA SS/GS class. Best so far is a 13.2 @ 104. Slicks, light weight (2800 lbs), posi (sorry, the stock LSD will likely break), custom axles etc.

If you pay attention to what a typical high HP FWD car will run, the mph is excessive for the ET. Especially if the car is street driven.

Case in point, an acquaintance with an SRT-4 runs low 13's @ near 106. Best has been a 12.7 or so at near 110....when he has the car tuned to kill and has the drag radials on.

If you are dreaming of 12's, better add at least 100hp, and hope the trans etc don't break. Of course most tracks have a floor jack they can haul you off the starting line with. After that, it's good to have AAA towing.

And WTF is NAWS? We used to, and still, call it Nitrous, or Spray.

Naws....dude!

I know my ass is coming back from English town with at least a 13.5 come spring. Don't see it so be any kinda problem. I may even be able to grab. high 13's with out dr's.

My motor mount comes in tomorrow, HRP opened up last weekend. I'm going for a 13.9 w/ the poly mount and K&N...

Having owned a camaro before I dont understand where the huge difference in traction for RWD vs. FWD is being seen. We are not comparing either to AWD, which obviously offers the most traction. Fixing the Wheelhop is a pretty easy task with some good tranny and motor mounts and maybe a brace. My camaro had pretty bad wheelhop as well. With some DR's I think traction will be very comparable to a RWD car, though it won't feel the same. Also is 110mph for a 12.7 second run really excessive? Maybe I am wrong but that sounds very reasonable for any car.

RonSS

My former 70 SS 454 Chevelle ran a best of 11.90 @ 112, with slicks.
Typical runs were in the 12.0 range @ 110.
FWD cars shift the weight to the rear tires just like a RWD car. It's plain physics. Hence they don't hook up as well.
To a certain performance level they can however, but not in anywhere near street trim. This takes a full on race car setup.
My Chevelle had only simple traction bars and slicks. 500 hp didn't hurt either.

You will notice that the weight transfer and power bands of RWD V8's and FWD 4cyl changes the trap speeds a lot.

Take 2 cars with the same 1/4 mile time. The V8 RWD typicaly has a much better 60 foot time, and a lower mph. So 110mph trap speed on a V8 with a 12.0 time...is likly a 12.8-13.2 on a FWD.

gforce477

Then how come there are so many modern modified muscle cars like the camaro and firebird running 12.6-12.9 with traps between 107-111.

And I do realize there are cars with excellent traction that do run 12.6's at 106-7 and such, but I don't think the difference between FWD and RWD is as big as it seems. I do realize RWD is better, but by that much? These guys both had DR's as well.

I also know we are much lighter but does anyone know the F/R weight balance on our car vs. other RWD cars, does that fall into FWD's favor having more weight over the wheels?

wasey13

No offense guys, but this is a very very sad thread. With 260hp and slicks your guys' cars should easily hit 12s. Drop a couple 100lbs. and it should be even easier. Like I said before you guys need to worry about putting the power you have now down before you start adding power.

FWD cars can run 12.8-9s and trap 105-108.

And Ron it doesn't take a FWD car being a full on race car to run 11s.

those that are needing to put power to the ground get a torque forward torque brace. it stops engine movement from inches to +/- 5mm ............ if you get stiffer engine mounts you WILL get vibrations and will become annoying. With the torque braces you get very very little if any at all vibration from them and it will stop that annoying wheel hop and get that power where it belongs........ the ground. Trust me, i have the dual setup and it has done wonders, when i first installed them and felt the difference instantly, i was speachless. there is no need to go spend $$$'s on engine mounts when the stocks will hold with torque brace system. All bolt on for very quick and easy, i mean easy install. just 3 bolts and 2 nuts to undo and put back on just for the plates and 4 bolts, nuts, washers and spacers to install the braces. The dual setup will extremely help with those that are haveing troubles taking off at the track and since it stops movement it helps the tranny stay in place while shifting so you can hit every gear w/o troubles.

The company name has change from Ironman to Torque Forward. (old install sheet)

I know the limits of the 2.0 havent been pushed too much in this community but i cant see it being as hard as you guys make it seem to hit 12's in this car. I've yet to take my ss/sc to the track but my previous car was a 99 gtp and ran 14.28@95 completly stock. I added a CAI, 3.4 pulley (raises boost by about 3-4 psi), a 3" downpipe and 2.5" catback and ran a few 13.5's @101 and tons of 13.6's @ 100(all stock pcm code). I know the GTP has lots more torque but its bigger, is automatic, and isnt intercooled. It also doesnt have any forged internals. That being said i think our internals can stand up to more than 300hp and 12's can be had without opening the engine.

theBLUEone

Whats their site?

RonSS

What I meant was that it takes a full race setup in a fwd car to get the ET to match the mph. In other words to run 60ft times like a rwd car.

I see fwd hondas in the 11's all the time at the track, however, they run near 140mph, and they are street cars.
