The motor has a lot of internal stuff done to it. Cam, roller tip rockers, forged pistons and such. He ran his first pass and landed 15.4, 2nd pass was 15.2, third pass he tweaked the timming and fuel pressure, changed his launch method and pulled out a 14.9. This motor is totally streetable. He is planning on hitting the nitrous to it seeing as it was built for nitrous use and see just how much he can shave off of it. But 14.9 out of a 2.9 with no power adders is something to say congratulations to. His car is as fast as most 3.4 guys. And almost as fast as the stock guys running mild nitrous shots.
Oh and this was done with stock exhaust manifolds, ported and stock TB. So anyone that says you need headers or a Big Bore TB. Look again. If enough people want the exact specs on the motor I will post them up on this thread.

just to let you know that capt messed up when he said that I have roller rockers, I am actually running stock rockers, next plans for the motor is long tube headers, carb, 150hp shot of Nitrous, custom exhaust,and readjust the rockers (there are a couple out of adjustment right now)

I am nearly possitive that your motor has roller tip rockers in it. The next time you are over, we are pulling your oil fil cap and checking it out.

yea looks like you might be right anyways here are the specs:
Forged TRW Pistons 9.01:1, Molly rings, Clevite bearings, ARP Head studs & rod bolts, performance 0.039" head gaskets, Comp 1.6:1 roller tip rockers, Comp 130 lb valve springs, custom grind cam .484 ex and .468 int. with 110 seperation if I remember correctly, Comp Magnum lifters, I cleaned up the heads, intake and exhaust manifolds, gasket matched everything, new timing set,MSD Digital 6 ignition box, MSD Blaster coil, Aurora 8.5mm spiral wires, Heads decked .020" and block head surface resurfaced (maybe 0.003' off), shaved and realigned lower intake plenum to match, block was bored 0.040' over, crank was machined and oil galleries champfered (block as well).
As far as fuel delivery goes I think I have that covered, I am using the corvette fuel pump and the 17lb/hr injectors from the Rustang.

A 1/4 mile time of 14.9 using a modified 2.8L V6 is certainly believable, especially if the gearing is low. A while ago Joe McGee ( then living in So. NJ) ran consistant high 14's with a modifed 2.9L and he ran an automatic with a 3.33:1 FDR. In contrast a couple of years ago Shaun Hammit bolted a 50HP N2O kit to a stock 2.8L and ran in the mid 14's. So if a Fiero owner doesn't wish to do an expensive swap and modifys the 2.8L , respectable performance can be obtained. All things being equal with the engine, it should be noted that the notchbacks should provide a faster 1/4 mile ET as they are lighter than the fastbak GT's. .

Tsk tsk tsk... dennis! I guess you missed the thread where I carefully weighed each and every part of both (during my conversion).
Total shift - 13lbs. 10 of which is in the heavier GT tail lights!
If that much is going to make a difference (that WE could ever tell!), leave your jacket, wallet and lunch bag with a buddy when you race!

The first is him with a good launch and beating some ricerized Eclipse. The 2nd one is him wtih a really really bad launch racing a late model Caviler, he quicly catches up and blows the guy away.
Total video is 2.89meg in size, contains to races, poor quality.
The 14.9 pass came to late in the evening to show on the camera. Sorry.
http://www.captfiero.com/reddragon.wmv I only have total 187kBps (1500kbps) outbound speed so sorry if you get crappy speed. But be patient this is hosted on my home internet connection.

Can I get a small dig in though? Comeon... let me go HAHA!! Simpson style at that reaction time :-)
Did they have to knock on the window and ask you to head down the track?
End of dig. Was this first time at track as a competitor? If so, next time practice leaving on the yellow that gets your reaction time better... don't wait for green. If that tree had .000 as perfect like here, you 'slept' at the light for almost a full second. I suspect it's a .400 or .500 tree and you just need to try leaving as the second or third yellow come on. Play what you leave on during 'time only' runs next time. It's a lot harder to be consistant with a stick car, but a customer of mine hit a perfect light (something I've never done) his first time out racing.
Damn I'm funny... also spent last weekend at the track watching 10.90 and 9.90 index cars displaying the biggest buck for the exitement bang as they consitantly rans the number and were fighting over who could run .000-.001 reaction time over and over with delay boxes and throttle stops... boy those are boring to watch. I'd much rather watch a 14 second (and your now one!) car try to stay in front of a faster car or catch a slower one, shifting your own gears, pushing your own throttle!

This was a Pro Tree. There is a single yellow then green. No count down lights. You stage and and light your stage light, then you get a single yellow and then green.
Ya his reaction time sucked, but it was his first time out this year, and first time out ever with this car. Launching at a race track like Mission raceway that puts the street guys up right after Pro Street guys so the staging is so stickey you can hear your tires sticking as your idle up to the lights makes it kinda interesting. You can not launch the car the same way you do on the street. You pretty much have 3 options. Clutch Dump at 6000 to break the tires loose, and pray you dont break anything, Clutch slip and pin the gas, or bog the motor. Chris was running his small tires that night 215/ or 205/60/14's so that he could get better gearing at the track and the tires were fresh out of storage and hard as a rock so he was having a bit of an un-usuall time trying to launch the car just right.
But you cant argue with his 2.0 60ft time. He took a little more time to leave the light, but he left the light right and did not anxiously dump it or dog it.

It took me the while at the light cause I wanted to get the right rpm to launch the car and have found that it loves 4000 rpm, I wasn't worried about the rt I just wanted to get a good time on the car, and I STILL WAS THE FIRST ONE TO CROSS THE FINISH LINE in every race, so now that I know what rpm this car like I will be working on the RT's

Wow, Pro tree, I've never run one of those, that's not going to easy with a stick. I've never seen a track make bracket guys run Pro, must have some old equipment if they can't just switch tree for different brackets.
Your sixty foot times were pretty good, with that sticky of a track, a set of slicks and a hardcore launch and you should be able to work another tenth off or more.
Have fun with it!

We have one of the best tracks around. NHRA and fastest street car shoot outs run here. As a matter of fact the fastest street car in canada runs here, possible the fastest in the USA. Dipping into the low 7's this year and drives in on Legal Lisc Plates with insurance on the car. He is somewhere in the 210mph range at the top of the track.
As for why they make us run that kind of tree I think it is so that it is nearly impossible to red light. Most of the people racing are the F&F type of kids. When you redlight you dont get a time slip so it would piss many more people off than simply having a bad reaction time.

I've cut a .500 R/T on a .500 tree. The guy running the lights had never seen it before. I have a rep for being consistant. I'm holding the slip here in my hand. I'm embarrased to show it cause it was the first night at the dragstrip back in '97 and I only ran 16.7 at 84mph. I'm sure theres skeptics like BlackAzzGT so I am willing to scan and post if it comes down to it....

Yeah, and besides... in this case, your RT doesn't affect your ET, which is really all most people care about anyhow.
It's just a fun run anyhow, right?

well like I said I didn't care about the rt and most people out there on the friday nights do either, it all about seeing how fast your car will go down the track and if your new setup works well and was worth the money you put into doing it, just waiting to see watts and capt hit the track. I would love to see our whole fiero club go up ther and race their cars but there only seems like there are a hand full of us that are into that kinda thing

I just got the new chip in the car today and so far am loving it. (chip is tweaked to work better with my engine setup, seemed to open up a few more ponies)
Thanks Watts.

Well I just found out that I did this run with blown head gaskets, and the 1.6 roller tip rockers are robbing me of power, so the car is about 1/2 way torn apart in my garage and is getting fixed with hopefully a few more tweeks, it also now has a custom eprom in it which is really making the car more snappy.
Can't wait to see what this thing will do when the head gaskets are done, exhaust leak is fixed, the 1.52 roller tip rockers are on and the new intake that i am working on.
Will keep you posted as to how she does next time at the track

Going by your specs and your ET, Desktop Dyno show you are getting around 184hp to the flywheel. (This is guessing on your head flow so that number is a +/- 3%) With some tweeking you should be able to gain about another 5 hp or so. (The cast heads with a Fiero intake seem to max out around 190hp) Great job. Lest us know what it does when juiced!

Well I had her all fixed up and then she decided to blow her tranny up so it is out getting rebuilt, bad part is tonight is the last night for our drag strip this season so now I am forced to wait till next season, by then I hope to have her mated to a nice turbo.
