Well, once again, I steath-ally took my Fiero out tonight...
0-60 in 5.98 seconds with 2 problems.
First off the darn car doesn't hook up anymore. It will spin through 1st and second. When cruising along in second, it will spin them on demand @ whatever speed when I slam the hammer down. Got any suggestions?
And it took me AT LEAST ONE SECOND to get the frickin thing in second gear. Something needs adjustment.
I couldn't datalog the event cause it threw my laptop all around and knocked the battery out...it was kinda secure?!
Oh well, I'll tinker with the shifter and see what I can do tomorrow.
Dude, are you running the 3400SFI that comes in the new Grand Ams? How hard was it to mount? I've got a 99 Grand Am with the 3400SFI, and it is indeed a sweet engine. Hmmm, maybe I should swap it for the 2.8 in my Formula?

O-sh*t I’m in trouble! I'm going to have to do some more modifications to keep up with that. (jk)
Very cool! Sounds like you have some impressive torque. How is the high end horsepower? Does it pull to 6k rpm? What did you get for a quarter mile reading and rear wheel horsepower?

Originally posted by Joe Torma: Yup that's the one...but mine is out of a minivan. It wasn't that bad to install. It needed a new front mount, and a scoop/vent in the lid.
They now make a supercharger for the Grand Am. I'm trying to see if it'll fit...but the Grand Am forum people aren't being too helpful.
Cool! Which forum? I'm on http://www.grandamgt.com and they seem pretty cool. I don't think they'll be much help in the swap aspects, but lots of info on mods and such. Most of the people on there want to just buy a bolt on out of the box, rather than do fab work that Fiero people do all the time. They've got a few people running the supercharger on their 3400. It's supposed to up the output to about 260HP, so it's slightly stronger than the 3800SC.

Formula88: I posted a request on grandamgt.com asking anyone to measure how much room the supercharger takes up...because for me(us) it would be window-firewall side and may not clear the decklid hinge. Take a look at Modifications/supercharger Q&A
Well, nobody replied. I know any Fiero owner would be out there with a tape measure in a second!
Interesting...The supercharged 3400 does 0-60 in 6.6 seconds. I beat that and I couldn't even get into second gear!
88Formula: This thing pulls at all RPMS!!! I set the rev limter low at 6000 tonight. I never hit it. The motor is roller, and lives at high RPMs. With my mods, it is probably good to 7000 no prob. I didn't get a chance to do 1/4 mile or HP(don't know how much it weighs)
maninblack: I have 225/45/17rear (215/45/16front) Pirelli P7000s Got any tire suggestions? I did want to up the size to 235/45s. Maybe if I put the interior back in it will help?!
This car is now like "new" to me...I really got to get used to it!

Well, I think only 2 or 3 people on the Forum actually HAVE the supercharger. It's only been out a matter of weeks. They have a Forum dedicated to the supercharger mods, under Modifications. If you didn't post it there, try that. Or check back and make sure you bump up your post. It may not have been seen, yet. You might also check with http://www.partsforyourcar.com since they sell the 3400 Supercharger, they might be able to give you some info on it.

Good numbers Joe. Gives me something to look forward to.
With you spinning the tires I would try to add some weight to the rear end and see if that helps. Like put a 30 lb bag of dirt in the truck or something. Sounds funny but it could actually make your car faster. Putting the interior back in will probably only add 50-60 pounds and with it not being over the drive wheels probably won't help much in the traction department.
What you could do is get some different tires. I dont' know how sticky/soft the tires you have on now are but I do know that the Nitto NT555 extreme are a good sticky tire. It is a drag tire and a street tire. Might wear out fast on the street though cause it is probably a really soft compound. Also the street you are testing it on plays a part too. Perhaps finding a different road will allow you to hook up better. Concrete surface will have a higher coefficient of friction then ashphalt so if you can find one of those roads that might get you a lower time.
Not too familiar with the manual trannies but it might be as simple as adjusting your shift linkage to get it to shift better.
Keep us all posted when you get new times.
I have a few more questions that I will PM sometime later this week.

New tires are probably my best 1st step on getting this thing to hook up. I kinda do and don't want street legal drag tires. How does the car handle with them?
The Pirellis are pretty soft, but I won't get them again. Way too expensive and not that great. Any other tire suggestions?
The supercharger is $3600...a little expensive, but...I just gotta have it!
Yeah, I don't know if the interior will help...but the stereo and amprack will! I was going to make the amprack removable, but I guess not now.
I didn't realize what was going on that night...Is this possible: When I was acclerating hard in 2nd gear, the rear end felt real squirmy-I thought it was my alignment.
Could the power have been alternating-flip-flopping between wheels?

Where could I go to find the engine complete w/ supercharger? Trying to avoid the dealer (overpriced). I guess it's unavoidable as it's a new(??) engine?? Please let me know.

Do any more testing yet? I got a ride in a v8 fiero today and man what a ride. The torque really snaps you back. He has a 335 horsepower 350 v8 with a four barrel carburetor.
This might be a stupid question, but here goes. If you are going to put the 3400 in your car then spend another $3600 on a supercharger, why didn't you just put a supercharged 3800 in??? If you want the 260 HP you can easily get that with the SC 3800 with a simple $100 dollar pulley swap!

Hey Joe! I'm interested in sticking a 3400 in my daughters 85GT. (the cobalt blue one that was in back of the house when we did the A/C conversion session). Can you tell me about what engine you used (what year)and what computer? Sounds like you are making changes to the computer so it must be an OBD2 from the donar car? What type software and adapters do I need to talk to the computer? Thanks Jim Gilbert

Hi Joe, Pzeros stick pretty darn well... Other than that, you're into 'dot' drag tires, which are kinda scary (and wear very quickly, not just acceptibly quickly, like in less than a month they're gone)
Up the width, try 8.5-9" wheels with 275 or 265 section rubber.
With your stock wheels, if they're 7", then 235width is really pusing the upper end of safe width. with 8" tyres you can run 245 or even as high as 255...
Best! Benn

That and you get a 3800 series 2 buick motor that is proven reliable from so many cars that have used that design for so many years.

No offense, but the 3800 is a heavy motor. The block weighs 50lbs more than the 3.4(or 2.8) Its got nice'n'heavy iron heads, mine are aluminum. Not to mention that the 3.4 is just an overgrown 2.8...so it was engineered to live in that engine bay. And the 3.8 is not even that much more displacement.
Desktop dyno says I have 300hp...I plugged in some 3.8 specs and yeah I get 220-260 SC'd. I have seen 3.8 installs and they are very nice, and yes the motor is reliable...but I wanted to be different.
NEW TIMES.... I did a 14.69 @ 90mph 1/4 mile..BUT after taking it a little easy in 1st, 2nd, I romped on it in 3rd and the a$$ end go so sqirmy I almost lost it...I let off and started to brake a second or so before the G-tech was done.
I'm going to go over the rear suspension tomorrow and make sure everything is in order.
Ben... My rims are 7.25. I'll look into Pzeros. The 235 should be ok right? I may have to do an Imsa kit to stuff 9" rims under there!
Jim... If you're ever in Jersey, stop by! I ditched the OBD computer and went aftermarket(kind of expensive). Software is included all you need is a serial cable and a laptop(or a long cable!). I've made 6 revisions on my engine program so far.
