Definitely interested. If you could get a pic of the 'underside' for me, that would be sweet. (I want to know how much room is between the fuel rail and the plenum.) I'm thinking of running a hose under there. Plus, that thing's gonna look pretty sweet!

Glade you like it Raydar. As for room Funky, if I wasn't in a hurry, I would have run my turbo coolant lines through there. When I switch back to stock and then back to ours for the dyno runs, that's what I'm going to do.
DYNO RESULTS ARE UP FOR A 3.4 looks like 14 hp gain.
------------------ 1986 Pontiac Fiero GT Auto, soon to be 5 spd Getrag from 88 z24, Best 1/4 = 16.1 at 83mph, mods, wires, CRX intake, and power pulley. Planning Turbo 2.8 swap for a little more umph!!!!
Bought for 2500$ Canadian.

still curious as to how much of a gain would be had from a good 5 angle valve job on top of this? hmmmmmm.

M0sh_man's car was the 3.4L that was dynoed today with the new intake. He is on his way home now (6hour drive) and will probably be telling you guys all about it later. He said he gained about 14hp. He has not yet driven the car on the road so he doesn't know how it feels yet. I plan on driving it to see if I can tell a difference too. I'm kinda excited to see what it looks like and feels like. We'll let you know
Thannks for the updates! That's quite a jump! Was that with a long runner or short runner manifold? I'm curious as to what other mods Matthew has done to his engine. I know he said 19# injectors and bored TB. I'm curious as to which cam, etc. I'm thinking a good cam and a port job on the lower intake and heads would really wake up a sleeping beast.

ok, im going to let troy post the dyno results, and let them speak for themselves, i was very happy.
STOCK 3.4L camaro motor with stock fiero intake system (no mods to intake system) with ported fiero exhaust manifolds and 19# fuel injectors put out 128.9HP i believe, and 183ft/lbs of torque at the wheels, using the stock fiero prom.
when we put my car on the dyno, troy was running it, 3rd gear pulls, the car would pull to 5300 RPM every time with the stock intake (made 2 runs i believe) and both times it hit a wall at 5300 RPM and the HP graph just dropped like a brick, pobably 30HP every 100RPM above 5300,
when we first put the new-intake on we noticed that it immediatly pulled further, after some chip tunning, changing the fuel maps, and actually retarding the timing above 4000 RPM by 1.5 degree's we ended up getting 141.2HP at the wheels with the intake on and a bored throttlebody. (darrell morse 57MM throttlebody) i can honestly tell you i have no clue how much torque it was putting down, cause i didnt even ask.
the MOST important part of the intake.
once intalled and tuned, we were running the car to 6500 RPM and it still had a stead amount of power, the dyno graph will show it. id say at 5500 RPM i gained 50HP+ at 6000 RPM id say i gained 80+HP
i probably let franks cat out of the bag, but im pretty excited.
just so you guys know, my car is using the STOCK camaro valve train, stock camaro cam, stock camaro heads and fiero lower intake manifold, imagine how much better it would have done with ported heads and lower intake, and a high lift cam.
my next mods going to be 1.6:1 roller tipped rockers, seeing as you can change the valve covers without pulling the intake.
it took me and frank 2 hours+/- 15 minutes to put the intake on. the brake booster plug-in was made for 85-86 intakes, mine being 87 with a larger tube, we had to adapt it, which is very minor.
BTW for those who choose custom colors on their intakes, DONT CHOOSE WHITE. it doesnt look near as good as the chrome does, the near chrome powdercoat shines just like real chrome.

edit:
Raydar get a modified chip, if you think your car is running rich, it probably is if your using the 19# injectors, mine was at 11:1 anywhere above 4000 RPM

Thanks for posting all the info. My car has a chip that Jeremy burned for my engine with the bored intake and TB, so it might be a bit better in that regard. I was thinking about putting the stocker in, for the interim, but I'll just leave the tweaked one in. The rockers are next. Would do them today, except I'm going to Ed's to pick up a part. Catch ya' in a while.

We'll send you a new chip soon Raydar. Sorry we didn't get to do my car. We got there a bit late and by the time we finished up with Matt's car it past thier closing time. Knowing how my very modified 2.8 hit the wall somewhere above 4k and seeing what the manifold did for Matt's basically stock engine, to say that I as disapointed in not getting mine on dyno would be......... well you get the picture. Even so, I'm exceedingly happy as our manifold did a hell of a job in knocking down that 4k-something wall, and did so without adversly affecting lower rpm! After all that hard work (around a year) and $$$ I just have to say it, holy sh#$@** it works even better than we hoped for! Oh, and here's something else about Matt's dyno runs, you should have seen the smile on his face (and ours) when we heard that engine rev to around 6500. Troy had to bump the rev limiter to do it and it sounded like could have kept on climbing, but with his motor being stock, Troy didn't want to break it. No more HD sound for these engines, we're going to make 2.8s near scream! We'll be back at the dyno maybe in a week or two with my engine.

I'm convinced! Saving my pennies for the last year was definately a good idea. A few more and I'll be ready to buy. Troy and Francis, you guys are awesome!
I talked to Oreif at one point and he told me that a Darrell Morse ported TB flows just about perfect for a 3.4l pushrod V6, meaning then that it flows more than enough for a 2.8 Thats what I'm going with.
Send me an intake and I would be happy to see what happens to a 3.4 pushrod with a turbo installed (currently has 19 pound injectors and stock Fiero intake with WCF cam).

I installed this intake (long runner) on my 3.4 automatic (yes I know, auto) I have been very pleased with the performance. Even gets better gas mileage.

Mosh has a short runner. I have a 2.8 with a long runner waiting to get on the dyno. We will post dyno runs with my turbo disconnected from the TB to see difference between ours and the stock manifold. Afterwhich, we'll reconnect the turbo. Aside from my turbo, the engine has lots mods so it will give everyone a good idea as to what you can get from 2.8 N/A engine. My 2.8 Mods: Crane 50-states-legal cam with hi-pro springs/lifters/etc, 5 angle valve job, some head porting, custom headers, 9-1 pistons, MSD 6200 box and coil, our manifold, empty cat, and a super balancing job. I have a few other mods that just seem to recal now, but should have a good picture by now. And engine still has a stock TB. For the turbo run; 6 lbs boost with an MR2 air/air fan asisted intercooler and MR2 BV. With all those mods and no turbo my engine hit 4500 rpm like it was a brick wall. Just looking at Matt's chart, I know it's going rev and make power like SOB with or without turbo.
