3.4 DOHC powerband what would you change? top end build qs.

hey prosped, PM me, ill end you in there, quit brining your stupidity all over the board

 

The bottom end of a 3.4 is not bad for a dohc motor when N/A but when tuning it for a turbo, you are going 2 want to put in a little timing, which might hurt the bottom end, but will be made up for with that hairdryer install

 

BTW, my turbo 3.1 and 3.4 dohc had about as much bottom end as each other, but since I have not been able 2 really drive the 3.4 yet, I cant tell ya about the top end power of it.

 

Your 3.1 turbo was a heap of shit, poor gutlass supreme got ahold of that heap of shit you beat the hell out of

 

Dude, you're gone, but you're pissing me off. You need to stay the hell out of other peoples' business. Seriously, this "oh you pissed me off so I'm going to find some way to insult how you treat cars" bullshit is going to stop.

wow talk about drama galore haha

[DaveFromColorado]

alright guys, quit pissin' on one an other..

 

Mr. Merkur.. I'd suspect it'd be a combo between timing belt stretch, and cylinder ware.

To me, it seemed like the 3.1 had more low end than the LQ1, but the LQ1 destroyed the 3100 in low end power.

I've driven 3.1's, 3100's, 3400's, and 3.4 TDC's and the pushrod motors always "feel" like they've got more low end grunt - but the 3.4 does get up over 'em body for body.. obviously a TDC w-body will be heavier then a 3.1 J-body, but you get the idea.

This has come up before, but I'll state it one more time. According to my FACTORY dyno graph, the 3.1 LH0 is already making 175 lb-ft of torque at only 1600 rpm. I sincerely doubt the 3.4 DOHC is making that much at such a low RPM. However, we won't know for sure until someone posts a factory 3.4 graph.

 

Either way, all are good motors that I think should be appreciated for their strong points.

Can't argue with that.

I have a 92 3.4 GP, and I would say, just from experience, that low end is not its strongest point, but it doesn't suck.

 

I think anyone who is smoking tires through first and second gear:

 

A) is lying OR

has terrible tires OR

C) is confused about what engine they have OR

D) has lots of mods

 

I raced an M3 from a stoplight, uphill once. I pulled away off the line, got about a carlength ahead, and then when I was reaching the top of second gear, he shifted to third and disappeared. I think that suggests decent low end power, but doesn't say much for the GP's top end. I wish I had a 5 speed...
