So you had a 1.3psi increase over the M62's 2.8"... by using the TVS with a 3.34"?

Am I right on that one?

 

yea me and witt were actually just talking about our stock maf in a 4 inch pipe...

 

Yeah, thats about right. My ambient pressure is 14.1psi here.

 

what are the stock pumps dimensions

 

i got a walbro gss342

 

Saw this blower of FAIL tonight, NAWT impressed.

Has a pulley the size of a harmonic balancer on it.

Weaksauce

 

diaf.

I'm looking for them. I had a spare and took measurements from but can't find the damn info now.

 

GTO Key Owns Brand New TVS with Harmonic Balancer Pulley... Story @ 11.

 

I know you believe the LSJ with the TVS is faster, but did you really have to swap the LS2 out for it?

Hmm, from what Paul has been posting about running the MAF out of range on his turbo, I'm thinking if the PCM can continue to convert cylinder airmass from frequency at higher than 11,100hz tweaks can just be made in the PE table.

I'll get it to work one way or the other when I swap pulleys, its just getting the fuel there that's going to be fun. I'm seriously considering the Aeromotive Digital FMU at this point. I already have the required pump.

 

Witt, how did you get the 79# injectors to work out and where did you get them? I thought I saw something back awhile ago, but I can't remember where. Just curious if it's a pain in the ass to control them HPTuners.

 

Racetronix.

They are disc style and easier to control at tiny pulse widths compared to the pintle style 60s.

 

A walbro gss342 does not fit inside the black cylinder module in the fuel tank. Is longer than stock

 

I was under the impression that with stock internals and 60's it was possible to run it. Or was the video with the IRL not safe?

 

How is the low-end? Does it seem to lag as much as the M62 did? More or Less?

Is 35 to 40mph still right about where it takes off

 

Well, it seems with all the fueling problems, I might just go with a relatively large (haven't decided size yet), in-line pump, and pretty much remove all the stock fuel system (remove stock pump, install larger fuel lines, inline pump, return line, and regulator, and just hook the pump up to an on/off switch), with a set of 83 lbs/hr injectors. :shrug:

 

it completly blows the tires off with no effort, all around more power.

 

Amazing... that would mean (in my eyes) that there is A LOT less parasitic loss... because I think that is what really kills us down low with the M62. Like second gear doing 25 is just dead.

 

witt the maf is gunna be accurate to 11250 hz and after that you can just add in with pe.

blown4banger go with a intank pump, the external are noisy and unreliable. the pump is acctually cooled by the fuel around it, so a external pump is gunna run hot and that shortens its life.

and i dont think anyone is gunna need larger than a 3/8 fuel line from what i've seen

 

well im barely spining this blower half as hard as i was the m62, it's hard to completely say though i would have to go out and dyno to lay the final verdict down but i can say pretty much it will make more power all over.

 

When is everybody going to the dyno?

 

I'm surprised Witt's **** isn't in a thread by now. I'm waiting patiently, figure I may get a PM at some point...

 

We haven't even gotten decent videos yet. The weather here fucked us the first night.

I'm hoping he gets time from work to put the 2.75" on this weekend, I want to see first hand how that fkr compares to Dans RL and my 2.5 pullied car.

 

F*uckin' weather...

 

****** weather is right!

 

you ever race a stock cobalt, think of that

i ran out of fuel so i have to try a few things to see if i can band aid it if not it may be a while.
