300HP+

[v6h.o.]

ok. im used to seeing that refered to as Deg Dur @ 0.050. not just ".050 timing"

[SappySE107]

Oh, the saturn engine. There is also a 3.5 DOHC called the shortstar which is not. http://media.gm.com:8221/division/20...vue/specs.html

Ill have to include this on the site, but there aren't any saturn owners here to share info. This site is constantly growing, not because we all think this is some "bible", but as a hobby site where the members input the information.

So, if you don't wish to share the rest of your information with us we really don't have any use for you being here either. It seems a few people have joined this site lately trying to be the know it alls...but that is not accomplishing anything. All talk, no proof.

And for your cam timing measurements for measuring the crank...wtf dude, that is the cam comparison, not the crank. The cranks are identical, the cams are obviously different between gen 2 and gen 3 as gen 2 is flat tappet and gen 3 is roller. If you want to compare stroke, then measure the throws.

yeah ok i think what is happening here is i say one thing and then another and then they either get combined or switched around
i say we just try to figure out things rather than argue cause noone learns when we do that

Is that 3.5 in the Saturn actually part of the same family of 660? It has very different specs from any other 660 that we are familiar with.

Like the Aluminium block, 10.0:1 SCR, SOHC, 93mm (3.66") stroke, coil on plug.

Although some other things seem familiar, like the refernce pulses for the ignition (7), 89mm (3.5") bore.

Oh well, if it is, it is, if not, well there are more things than just degrees of seperation of the cylinder banks to make it part of the familiy of engine we like.

The 3.5 in the Vue is a re-badged Honda engine, not GM. It is a 60 degree engine, but that is where the similarity ends to the rest of the GM 60 degree V6's.

I was wondering about that. I knew a few years ago, GM and Honda had been talking about an engine program, just didn't know where it lead to.

[ikessky]

Okay, first and foremost, I started this thread to talk about how to get 300+ HP out of my 3100. Not to piss and moan about what's a 60 and what's not. Why does this whole thing have to be a secret with you rave? If you know information, why don't you share it here? Why would I have to contact you privately to find it out? No real offense intended, but what the heck!?!?!? I'm here to learn and share what I already know.

Now that that has all been said, Manticor, thanks for the info. I will be running off of an OBD-II computer. I'm thinking that I will want to work with a place like DHP (or if I can find someone locally) to mod my computer to work with my mod plans.

Is OBD-II going to accept low boost (like 4-6psi) without throwing a fit?

[RacerX11]

I think the guys running the Eaton M62 kit on the 3400's are able to get by without computer mods on their low boost levels (~5-6 psi for the stock kit). I think they are running an AFPR, but that is about it. You should be able to get by as well.

Marty

[ikessky]

I'm kind of planning on an AFPR anyway. Thanks for the help. All these things are good to know!

[SappySE107]

I would look into some sort of computer tuning if you want the most from your mods. Stock computer may run it with a fuel pressure increase, but there is quite a difference between getting it running and getting it perfect, especially when your goal is 300 hp.

[ikessky]

So, theoretically speaking, how much of a gain would 5-6psi get me? If it's ~50hp, that is pretty much what I would like.

[bszopi]

I'll have to check what the GA guys are getting on the dyno and give you some numbers. But 50hp seems in the ballpark.

Here ya go:

Computer tuning is a must, had I been able to propler tune my POS ODB 1.5 computer (damn 95's) then I might have been able to eek 5-15 more hp and torque out of my setup. Since there is no support for the ODB1.5 system I plan to use a custom PCM as it seems to be the only way to go.

I just need to decode the stock GM fuel tables to use as my reference. Anyone have info on the stock fuel tables for the 95 3100/4t60-e?

As far as I know for low boost the ODBII wont freak out but you may want to invest in a Mini AFC as well as your AFPR.

As a general rule 1psi = 10hp though not entirely true all the time.

Pardon my ignorance, but what is a Mini AFC?

[Manitcor]

Its a small device the plugs in between the MAF and the harness you can use it to do some basic tuning of your Air Fuel ratio (if you have a MAF that is which I think all OBDII cars do if im not mistaken). ZZP Sells 2 kinds.
