Nice write up. So 3.1 pulley it is. Thanks man. I was not trying to go too crazy. Just enough to to make 300 whp.

80s will not make it any harder on fuel the tune will determine that

the op does not need a meth kit to run a 2.7 no one does if you decide to run a small pulley step up and put good fuel in it not a band aid as for 80s there is always down the road and why loose your ass trying to resale 60s and if the tuner cant get it to idle right on 80s get a new tuner and if you want to pick at stuff you can get a vacation

I asked because I honestly wanted to know if there was an advantage. From what you said there is no advantage (performance wise) other than future proofing. As it sits 80's will perform no better than 60's (based on what you told me).

As for the meth, race gas doesn't make a very economical daily driver fuel. E-85 is not available in my area. There isn't even an 93 in my area. I am very happy to have methanol injection as a viable option. Band-aid or not it allows me make good power.

Not sure what you are saying about picking at stuff and getting a vacation. You threatening to ban me from the site because I get on your nerves?

80s are better they will support more airflow

you were in the wrong and you dont need to keep running your mouth and intentionaly picking at something that is done and over with

To clarify, they will not perform better than 60s in OP's situation. They will support further growth of the build because they can support higher airflow IF OP would pulley down or go to E85 in the future. They are better in the same sense that 3" exhaust is better then 2.5" exhaust.

I would disagree I was in the wrong but we already went through all that and it is done like you said. I just have a feeling that you may be holding a bit of a grudge. Please forgive me

My 2.7" setup uses way too much fuel haha. I wouldn't bother with 60s. Do 80's to start and have the overhead to play around with

BigMajin

Thanks for the build advice everyone. I will install everything by mid next month. Engine rebuild with springs going to installed too.

unless your going to put cams in springs are a waste

3 in or 2.5 in aftermarket exhaust won't be necessary either. (Unless OP wants to make more noise)
The stock catback will not have a issue supporting 290-300whp.

I made 423whp on a borla 2.25" catback, with power climbing all the way to 8400 RPM.
This was in conjunction with a OTTP Long tube and 3-2.5" catless mid pipe.

I think I read that somewhere else. That's why I opted to stick with my GMPP kits piping and just get new ZZP resonator and muffler to replace the old muffler and resonator, rather than buying the whole 3" ZZP exhaust kit. Saved a bit of money for other projects

Yeah guy named Steven Flit / Ethyl Methyl (ME) said it on facebook.

SS_MuNky

Nah, it would of been on here somewhere... I check facebook once or twice a year

I think it was your "Cobalt SS LSJ 2.0 SUPERCHARGED BREAKING THE 400 WHP BARRIER!" thread.

I just thought if you can break 400 with 2.25", 2.5" will do me just fine... I've only got 300hp in my sights (for now... I'm sure when I hit that, I'll get bored of that and want more, that's just how it works)

That was my exact point when I mentioned 2.5" vs. 3" exhaust. Bigger fuel injectors aren't going to perform better until the flow requires more fuel than is safe on the smaller injectors. Just like a 3" exhaust isn't going to perform better until you are flowing enough air to need it. Both make it so you wouldn't have to monkey around with changing exhaust/injectors again if you made enough power to need it in the future. Otherwise neither is really of any benefit. That was the analogy I was trying to make.

I just want OP to know the facts so that he can decide which route he wants to take based on facts instead of opinion. Too many people on here tell you to do a certain thing, then they get riled up if you don't just blindly trust them and ask why. All I wanted to do was clarify the reason WHY OP should just forgo the 60's and get the 80's. What I gathered was the only reason why is to future proof the build. Of course if there are any other benefits those should be posted as well.

I'm really not trying to be an antagonist when I ask people why they recommend to go a certain way or what the benefit is. I am legitimately trying to find out more information. Just like earlier I wasn't trying to tell OP he should just go with 60's. I was just digging for the pros and cons of going either way.

BigMajin

Well I will go with 60lb injectors because I am going to be focused on redoing the interior and getting a full wrap on car after engine rebuild and tvs install.

BigMajin

Well I am getting motor rebuild as we speak, I have the 60lb injectors on the way as well as the harness to support them. I was told that my TVS can be ran on 2.9 pulley with 93 octane with full cooling mods. I was going to buy Trevor Jolley's intercooler that I heard can be ran standalone without the need for heat exchanger etc. Also while I had the 3.0 pulley setup on stock blower with zzp 1.0 pcm I would also have a bad idle problem it would rev up and down continuously under 500k rpm and sputter. I was told it could be a solenoid stuck open, bad injectors, fuel pump, or throttle body not calibrated. The throttle body was brand new so I am totally unsure. No engine codes at all when placed on a OBD-2.

Cooling for our superchargers is done via water to air heat exchanges. There are heat exchanger cores in the intake manifold that heat water flowing through to an external radiator(or heat exhanger w/e you want to call it). Did you mean you can run Trevor Jolley's heat exchanger and remove the stock heat exchanger? Intercooler and heat exhanger are sometimes used interchangeably.

BigMajin

I heard with Trevor Jolley's Intercooler it replaces the stock one and doesn't need anything else supporting it.

100% METH

iTrader: (3)

You're right

It bolts directly into place in front of the AC condenser and radiator.
No modifications required

I made 423whp with nothing more than that front mount heat exchanger for cooling.
Completely stock intake manifold / laminova config. Don't even have option B

BigMajin

Nice!!!!

jdbaugh1

iTrader: (1)

I was just clarifying that you still need a heat exchanger. The part you are installing from Trevor IS the heat exchanger. It's not a standalone unit either because it still uses the stock laminova cores and pump.

A standalone unit would be like an air to air intercooler. You are just swapping out the stock heat exchanger for a bigger or more efficient heat exchanger.

BigMajin

Oh ok I got a full understanding now.
