3400 all motor hp potential?

[Bad99Olds]

Does anyone know exactly how much hp you can squeeze out of a 3400, N/A?

[AGT]

Billions and Billions of Horsepower :lol:

Really I think some have made 300 hp with the right accessories. That is about where the tranny will hold to.

[jackal2000]

all motor you are looking at roughly 200whp.

[BlackJack]

in terms of track times in an "all motor" street driven car, the best I've seen with a '99+ N-body is in the mid 13's IIRC.

blackjack, what are you looking at for numbers with your set up?

the only one that i know of that broke 13 was tim with his gagt @ 13.99

how much money do you have?

We've made 227whp out of a 3400 before, and based on some improvements we've made since then, I think we can get 240 or more with that setup. This is a more extreme setup, our Stage 3.

[WhiteV6]

I have parts on 2 engines that should break 250 whp, without destroying drivability. My heads and cam are on a motor making 222whp without any drivability issues at all. How is drivability with that stage 3 MMS setup?

driveability is fine. We had it on a car for about 9 months or so straight. We ate a couple tensioners during that time, but that's to be expected with a cammed 3400.

[WhiteV6]

Did you get the brakes/vacuum taken care of then, or was that a different prototype?

Dave on v6z24/60degreev6 has 273 whp or something in the 270s.

We had issues with vacuum on the first car we tested it on, this was the second car, same exact heads and cam setup ... no issues whatsoever with the vacuum. We even had a vacuum pump system ready to put on it just in case, but it was fine without it.

well said ion, well said


And this was purely a question to gauge just what the potential was from the big hunk of metal sitting under my hood without forced induction or nitrous

Are non-Aleros welcome to the event?

other cars are welcome but understand that the whole weekend is based on the oldsmobile homecoming show and if its not an olds, you cant get it in the show.

[TheEdgeofSanity]

so even if i brought my great grandma's cutlass ciera, then I could get in? i don't need an alero?

yea you could get in fo sho. kind of going off topic here....the show on friday is exclusive aleros and saturday is exclusive all olds.

[TheEdgeofSanity]

okey dokey...back on topic, would you get 300 hp by doing upgraded internals, tuning it, port & polish, and a bigger throttle body and a cold air intake?


its a possibility that in the next few years that i may buy my uncle's cutlass supreme for a daily driver and work on the alero to be the ultimate sleeper.

[Oldsnut]

ASS'08 is more of a fun & show event for our little Alero group sponsored by the Alero Chapter of OCA (Oldsmobile Club of America)which includes a road trip to the Olds Homecoming show on Saturday which happens to be one of the largest, if not largest annual all Oldsmobile show on the face of the earth.

Not a chance in hell without a pretty wild cam and large injectors. Higher compression would get you closer but i don't know enough to tell you for sure. What do you mean by upgraded internals? I have ported heads, uim, lim, 65mm tb, exhaust, and a tune with a cai of course and i doubt im close to 200hp, so 100 hp even with a cam seems like a bit of a stretch without higher compression and higher octane fuel. Milzy or someone else please correct me if i am wrong this is mostly speculation on my part.

[WhiteV6]

Well, if you are talking 300 whp, you better have a manual transmission for this attempt. Superdave is over 270 whp but with a 3500. Colin Wahl is at 222 whp and his setup is posted here. I ported the heads and he is running a 1280 cam, which isn't extreme but he is on the stock pistons.

http://www.60degreev6.com/forum/showthread.php?p=350197#post350197

I built a motor with 12.4:1 compression and my 1331 grind, ported 3500 top end, crank scraper, knifeedged crank, polished rods/shotpeened, balanced rotating assembly, 65mm TB, etc. He hasn't dynoed it yet or run it at the track but from his stories, its crazy:) I don't think its 300whp but with the grand am SE trans and torque converter, the full potential isn't going to be realized either.

[BlackJack]

blackjack, what are you looking at for numbers with your set up?I'm looking for at least 200whp, but if not I'll settle for 400.

We can still drink beer though right?:drunk:

With the right cam and heads combo and some high compression, I think 300 crank hp is very possible. The 227 we mentioned before is around 284crank hp, so when I mentioned 240whp, that was 300. Now if you're talking 300whp, i think it would take a lot more. 375 crank hp would be a gain of 200 over stock. I think a highly modified 3900 could do it, but not sure on a 3400.

Milzy, I like your site.

Probably in a few years or so I would like to do an entire stage 2 upgrade. The main question with that is the heads.

I bought a set of heads a while back from RSM racing and I had to send them back because of the extra air pump I have and the heads have a port on them for this. It's something extra for emissions and I never figured a way around it.

I would like the car to run in the high 13's. My best right now is mid 14's ;)

I think I have a set of cores, maybe two sets that have the AIR ports in them. We could just port those for you if you'd like, or you could delete the AIR system.

[Redog]

Sounds good

Same, but I hope for the stage 3 prototypes to become a reality by then so I'd get the stage 3'er.

[MilzyZ34]

We'll be adding the Stage 3 heads to the store very soon. the Stage 3 cam is a little aggressive, so we may end up renaming it a Stage 4, we'll have to see on that, but if you wanted to purchase a Stage 3 kit, let me know, and i could get one put together for you.

[mfuller]

Two ways to make big power naturally aspirated - revs and displacement.
Sure you can throw a larger cam in the motor and increase efficiency between porting and polishing......you can lighten and balance the reciprocatng assembly to free up some power (although generally, light ened parts give up some strength....nature of the beast), but eventually there's only so far you can go.
Where's the maximum? I don't know....but I bet you can get 300whp out of a 3400 if you really try.....all bets are off on how long it will survive though.

[WhiteV6]

Finding a transmission to hold up to it in an N body will be interesting as well. I would add solid lifters to the list, and stiffer springs than hydraulic lifters could take.

tcemotorsports.com (http://tcemotorsports.com) has the intake setup needed on their minus 1. 2nd to last pic is a good one:)

[Bad99Olds]

what would that strage three kit run price wise?

[shortcut]

I would think the largest deterrents to 300+hp would be cost followed by a transaxle that won't fly apart.

[-Alero-]

where are all the dry sump setups?

and still no one has attempted ITB's? come on only 12 hours of tunning :p

wouldnt ITB's require MFI and not SFI? sounds like a PITA.

[WhiteV6]

Its been done and no, it can be SFI or MPFI.

[nickbain]

ITB's on a 60*v6, wow i'd love to see/hear that! I saw a video of an ecotec with 'em and it was sweet I can just imagine what the v6 would be like!

[MilzyZ34]

The heads are the expensive part. We'll be releasing these soon, but I anticipate pricing to be around $1999.99 The price of the cam is the same, so it would basically be a Stage 2 kit plus the $800 difference of the heads, so it would cost $800 more than a Stage 2 kit.
