Track times= not good

3.4L Formula 5spd Getrag with a few mods went 15.56 at 84mph. On the dyno got 140 hp and 192 ft/lbs of torque at the wheels. The car will be getting a test intake in a few weeks to see what kind of gains we can get and this time it will be dynoed and tested!

My 87GT with a 5spd getrag 2.8L stock went 15.57 at 87mph go figure. Im still interested in what the intake brings to the 3.4L, hopefully some life to the darn thing at higher rpms.

15.662 @ 85.3 mph. 3.4 w/Getrag 5spd, ported exhaust manifolds, high flow cat.

That was with a broken front tranny mount and a bad dogbone, if that matters. In fact, I think the first launch is what killed the tranny mount, with the bad dog bone of course.

I always wondered what turbo 3.4s run, I've seen estimates and some horsepower numbers, but no track times that I can recall. If that's getting off topic, nevermind.

15.59 @ 87.74mph
getrag 5speed, and a few goodies on the motor. ive done a few more mods since then, and once i get a custom chip id like to see a 14.99.

3.4L 87GT

I witnessed (since I was in a car behind her in the staging area) Jen (Fierochic88) run a 15 flat (I forget the speed) in her '85 GT 3.4 w/4-spd stick. That was last fall at Maple Grove Raceway.

Looks like the extra shift with you guys running the 5-spd Getrag might be slowing you down in the qtr. mile.

I know Amir has headers, borla, etc, on his car...

Just wanted to lay it out that Jenn has a cam. For comparison sakes along with the 4spd. Well in anycase, she'll prob. be by to post.

Keep impressing me guys, I'm considerin a 3.4 due to the ease of swap. True, they're only turning 15s, and yes, my 2.8 ran 14s many times, but as far as turbo goes, I think a nicely boosted 3.4 will put out a bit more than a boosted 2.8.

Maybe its just me, but I'm not at all impressed by a 15.5 My formula ran a 15.7 - 15.9 all day long with 160k on the clock. I know the history of my car back to 30k miles. It still has the same Timing chain it did when purchased at 30k miles in 92. theres too many people running mid 15's on the stock 2.8 to consider that impressive. just my $.02

Is it possible the 2.8 heads and intake are makeing the 3.4 loose hp? Maybe the ECM even?

Heads for the production iron head 2.8L and 3.4L are identical. It's most likely the Fiero intake manifold design and ECM still running a 2.8L fuel map that limits the upper end HP. There are various opinions on that matter though.

And yea John, Jen is running a cam but I recall it's nothing real radical in profile.

The unavailabilty of economical lower compression dished pistons (other than the stock flat tops) drowned my 3.4L dreams. Can get a decent set of 8.5:1 compression dished hypereutectic pistons for the 3.1L bore fairly cheap. Yea I know I can go custom forged, yadda yadda yadda but I want something I can actually afford rather than something I can only dream about to go with my turbo, so a 2.8 to 3.1L rebuild it will be eventually.

14.9@92 probably could have managed a tad bit lower 14.5-14.7 but goofed my launches. Yes thats with a 5spd.

I ran a 15 flat on a track that had not so great traction, so I would bet a fairly large sum of money that I could probably beat that and break into the 14's. I believe my top speed was around 89-90 miles per hour. While my 3.4 has some mods, there is nothing major done to it at this point. The cam mod is only slight and I doubt it gives me an entire 1/2 second. For the ease and inexpense of the swap, I would recommend it to anyone.

Thats apparently what the problem is...you really need 20%+ more air for the 20% more displacement.

I have the GenIII 3400 FWD and it should be in the high 13s since it ran a 14.37(g-tech) and took 1+ second to get into 2nd gear. (kinda bench racing...but it's the truth)

15.2 @ 89 - that was before I had Wester's Garage ( www.ecmprogrammer.com ) burn a chip. My car runs stronger now, but still "runs out of breath" above 4700rpm
