Estimate HP for these mods.

[Canyonero]

In my email thread with Sean (who wrote the 4x4wire.com article on 60º power tricks), he estimated his engine at 190-200hp. He rolls on 35" tires with 5.38 gearing. He was wondering if he was overestimating the HP? Opinions on the article? He talks about building up the 2.8L, but the engine he is actually working on there is a 3.4L.

Summed up:
3.4L F-body
Tubro City TBI (slightly larger than the 4.3L TBI?)
Ported intake manifold
TBI Spacer
Amsoil Air filter (14"x4")
CAI (snorkle)
Headers
2.5" exhaust
Comp Cam (probably the 252H)
1.6 roller rockers
SuperChip
Power Charger (another intake thing)
Electric fan
MSD 6 Off-road Ignition

Sounds slightly underestimated to me, I would say somewhere in the 200-210 area at the crank.

[Barry]

But after reading the article, 20 hp from a throtte body? I think not.

Hmm. Depending on how good the cam and headers are, 185-190. That's my best guess. The iron heads hold you back a lot. Ask merlot he had a pretty rad 3.4l but it still wasn't anything impressive.

[merlot566jka]

yup, 150whp and 192ft.lbs.

thats with trueleo intake and headers, 65mm tb, crane 272 cam, 1.6 roller rockers, zero decked block, 7730 ecm, 2.25inch exhaust, 24lb injectors, knife edged crank, windage tray, hv oil pump, port n polished heads and intake, and all kinds of other crap i wasted money on.

go aluminum or go home......i learned the hard way.

that link that says its messed up actually works, you just have to click on it and hit play when it gets to the photobucket link....dunno whats wrong with it

[montess408]

damn merlot566jka thats a impresive build sheet there and probley expensive too ! but the power output is kinda low do you think that the gen 1 top end is what killed you on there ?
with that sheet i would have guess @ least 250 hp

[powerdoctor]

He's measuring rw h.p.. not fly wheel.

I am thinking something else is up there too with such a small output number at the rear wheels.

But for sake of arguement I won't say anything else.

The 3.4 is pictured in the thread, but it sounds to me like it was another example of what he wants to do, thats all.

A stock 2.8, with those small mods, might make 180/ 190 h.p.

If it was a 3.4 lower, I would say over 200 all day.

[Canyonero]

Was that build with the 2.8L or the 3.4L? (nevermind, already mentioned it was a 3.4L)

[Barry]

So u guys are saying that my freind with a stock 3.4 auto camaro isnt anything to worry about?

[IsaacHayes]

Barry, my friend had a 3.4l camaro with 5spd and headers and full exhaust, and a proper CAI. I was still stock when we raced and I had two friends in the car and I walked him with ease. I didn't smoke him but he was slowly moving behind me the whole time. 3.4auto stock is way slow. I've had close races with 3.8 auto's before when I was stock. Neck and neck with one of us wining barely. Now I have a good O2 sensor and big ports it would be a totally different story. 3.8 camaro's and GrandPrix GT's were a pretty even match for me back in the day. So 3.4auto is no contest!

Thats cool. Hes always trash talking my car because its a POS BARATTA and its front wheel drive.

My car is stock 95 beretta base, full lg8 topend(heads, rockers, intakes, and 3400tb(hopefully if that car is still at the yard). Il have to race him soon, ill have someone tape it.
