I will get the trany cryo treated and put in the phantom grip and hope i dont break it right off

The G6 6 speed is only rated to hold some 290 something lbs right? Not a power a holder If I remember straight.

The Fiero Getrag is rated at about 200 lb-ft.

The G6 6-speed, F40 (MT2) is rated for 245 lb-ft max engine torque and 295 lb-ft max gearbox torque.
I assume the 245 lb-ft rating is the torque rating of the engine that the transmission is paired with and that the tranny can handle up to 295 lb-ft - just GM hasn't released it with an engine that powerful yet.

By comparison, the Cobalt SS 5-speed F35 (MU3) is rated for 200 lb-ft max engine torque and 258 lb-ft max gearbox torque. (this is the one Loyde uses)

The interesting difference between these two is the F40 has a GVW rating of 3527 lbs while the F35 has a GVW rating of 5071 lbs. So, the F35 is not rated as strong, but for a heavier car.

Sorry, but Don has a best time of 11.32@116mph. He hasn't ran a 10 yet. While he is fastest on the forum( I don't believe any of the 10 sec. V8 cars post) look at his mph compared to X's best mph. I believe X gets 120's? So its just a matter of time........

I know that. But he's running faster than Ryan and without lunching transmissions. Ryan has to be able to match that 11.32 before he can beat it. Ryan's fastest time was 11.72 on his current drivetrain and it didn't hold more than 4 passes. With a setup similar to Don's, he may still break it but we know Don's transmission was good for over half a second faster times.

I was hoping X would beat Don's times. Then I could purchase the car for less (using someone else's logic)? Don has additional mods and the car needs to go back to the dyno before the next runs. It is built to take it. I will be taking delivery after the 8th of July. It's pretty clear looking at Don's runs what happened look at the 1/8th mile time vs. the 1/4 time. I won't speak for Don but the car has room for a better run.
Take care. Bill

almost 50% more than the 282 getrag is ated for though

And also back in the old days, when the Fieros were still almost new, I built a lot of Fieros with 400 to 450 Lb. Torque & never thought twice about if it was gonna stay together.

Now, when you put 400 Lb of Torque into a transmission that's 20 years old & has 200K miles, you gotta know the Transmission won't take what it once did.

Thanks to the Fiero aftermarket, you can replace virtually any moving part on the Fiero with a new & better than NOS part.
Up until now, the only moving part on a Fiero that you couldn't replace is the transmission. If you could buy a new "Fiero Spec" Getrag 5 speed "over the counter" then I would have never developed the 6 speed swap.

Someone had to step up & give the Fiero another 10 years of life. That's why I developed a kit for the F40 transmission. The kit I have lets you put this transmission into any Fiero. The guys that have my SBC's Won't have to buy another adapter plate or V-8 kit & the guys with the 2.8's & 4.9's won't need an adapter plate either.

Gotta go to work.

Actually its gone 11.54 @ 124mph on its current setup. It just went 11.72 last time out to the track. Dont worry, Ill go 10.70 soon enough. Im finishing up a job for a customer, and once I get paid, Its on

Ryan, what gears are you running in your car?
I believe Don’s car is running 3.69 gears.

Do the 3.69 gears and tall sidewall tires put less strain on the axles and trans in Don’s car?

I am trying to figure out how to get my axles and trans to last as long as possible.

Stay current, Ryan.

quote Originally posted by Don Kraus: Went to Bryon Dragway today after finding some of the hp that the dyno in Daytona showed we lost. But the dyno also gave us an idea where to find it. We ran three times. The first being 11.556 @ 114.12 mph, the second 11.508 @ 114.59, and after some more adjustments we were able to run our best of 11.323 @ 116.4 mph with a 0-60' of 1.491sec. Didn't hit the 10s yet -- but getting closer. We need to dyno and tune at the same time now and we should find the hp we need to get there with the changes I made this winter. See you all at the Dells! Don

My final drive is 3.33. My tires are 235/60/15 (drag radials), my street tires are 235/45/17. My axles do fine. Its the trans I have the most problem with.

This fiero has come into my possession (actually i'm making payments until i get my house sold, then its coming home) The motor when it ran a 10:30 is no longer in it. I plan on turning it into a daily driver/sleeper. It will probably make it to the drag strip once a year during fiero fun fest in Kansas city. Oh yeah its mid engine too.



Ive got more pictures if anyone is interested

Of course we're interested. Post 'em!!

1986 SE 350 V8

yeah, and what engine transmission was in that car for 10.3 runs?

As far as the tranny, i'm pretty sure the one that is in it now is the one that was in it then. I don't have access to it now, but along with the car i will get a big packet of receipts. Hopefully i will be able to get more info on the original set up. At one time the owner offered a photo journal with the specs on what he did to get the car there. I found the new number for his old business (C & C performance) and found out he no longer works there and i was unable to get any further info on his whereabouts.
According to the v8 archies site (i have yet to contact them to see if they have any info)
"this car was built for Drag Racing only and has run 10.30's consistently. This purpose built car is very fast and is a good display of Pat's business of building Drag Cars"
Even though this car was built for drag racing only, it is still very close to street legal, which i plan to make it.

I assume he is still in the go fast business in one form or another

So if any one knows how to contact Pat Ciarcia please give me a shout.

And I've run 12.8's with 260 at the wheels through a 282. It's not made of tissue paper. What's the matter with acknowledging that the one you had was a dud? Welcome to reality, enjoy your stay.

I will have to agree with Will, I run my highly modified 3800SC every day, VERY hard, and it is perfectly fine. I even have over 140K on the tranny, and I believe I have way more than 300whp. I am not sure why people are always putting down the Getrag.

[This message has been edited by Golden86 (edited 06-26-2006).]

i think the 282 will live as long as you dont do somthing dumb like side step the clutch at 5000 rpm then any trany is going to come apart any stock trany if you have traction or you will break some thing

bolt your getrag to my engine for 30 seconds and lets test it.

That would be an interesting test. Barring a drag launch clutch dump, it would be interesting to see where the failure would be and how long it would last.

No i will test it due to I am building a turbo 4.7 V6 chevy it started life as a Bush race car engine with 20 pound of bost i figure about 600 HP so the trany will get it's test

quote Originally posted by cooguyfish: yeah, and what engine transmission was in that car for 10.3 runs?

I could have sworn that i read it was a worked over 3 spd auto th-125. I might be mistaken but that trans pops in my head when i think of the " 10.3 1/4 mile car " as i like to call it.

quote Originally posted by fieroX: bolt your getrag to my engine for 30 seconds and lets test it.

Ok, but you only get 30 seconds. Nah... that would be way too much work.

We've been over this before, but it didn't sink in.

How much boost do you build with a free rev? That's how much you'll launch with running a stick. That launch load and 1.5 second 60 you think will break the trans right off? Gone. You'd be lucky to crack 1.9's.
You're engine can't hit the transmission hard with a shock load. You'd have to break it with straight up torque. Not saying it won't happen... but you can't even put together a built 4T60E to stand up to your engine... wouldn't be any surprise that a transmission rated for 200 ftlbs would break with 500+.

However, that's a whole different ballgame than your usual party-line, which is that they break if you look at them wrong. That's simply incorrect.

[This message has been edited by Will (edited 06-27-2006).]

if your looking for another trans, local fiero guy here just bought a 1999 grand prix GTP he wants the engine wiring and ECM, transmission will be forsale.

if anyone wants his phone number PM or email me with an offer and ill pass it on to him,

he purchased the car at a salvage auction, the entire interior was burned, but he said no damage made it out to the engine bay, salvage yard listed the car as 120k miles. rest of the car looked new other than the burn damage.

Yup, its still has a 3 speed auto
could be a th-125, i really dont have any clue though. Hopefully i can get the car paid off soon and start diging into it
