Pulley size on m45 supercharger!!!!

[guiguilandry]

So today I was at the track and I did what I consider a not so bad time with my beater... the LD9 S/C....

15.071@91.27
60ft : 2.281
R/t of 1.031

Now I want better times... In the very near future I will recieve my hptuner and I don't know the pulley size for the M45 that give 10 psi ???

I heard 2,6in or 2,7in.. is it true?? I don't know shit about the m45.
and if I change the pulley size, do I need a shorter belt ???
for now the beater ( old car of Vinalero ) have :

Gm s/c kit
180* t-stat
H.O. alt, 200 amp
2,3H.O. TB 57mm
Pacesetter header
Straight 2in 1/4 exhaust with no cat or resonator, only a dynomax super turbo muffler
WAI, not yet a CAI, I'm gonna put the battery in the trunk ASAP
I'm running on radial T/A 215's at 20psi on the track
also I have a short shifter
Cm coilspring and GR-2 shock
Crossdrilled and slotted brakes...

I'm waiting for your opinions on what I should do next.... CAMS, PULLEY, N2O

I saw up to 10 psi with the 2.6, but typically 8 steady.

Find a way to cool that hEaton down. Maybe do a meth injection kit too that should do something for you.

Wow look at the R/T :eek:

That's beyond sleeping on the tree

[Oldsman]

meth injection and cams and p&p head. also up to the 62mm TB

[Th0r]

A 2.6, tune, secret cams, header, and 2.5" catless exhaust netted me 14.4x's. So with what you have, just get a smaller pulley meth and tune. That should put you low 14's easy. Cams could put you into high 13's My GMPP kit injectors were almost maxed with the 2.6, so you'll probably want to go bigger.

Edit: I was seeing 9psi consistently.

test and tune, it's about getting the best elapsed time, who gives about how long you wait before going. i had a 3 second r/t once

[guiguilandry]

SO

Looks like everybody suggest the 2,6 and a meth kit. that's what I was thinking too... do somebody know a company that does the 2,6 pulley???

I'm not gonna remove the heads unless the headgasket blows... and for the 62mm throttle I'll need to port also the blower because the opening is the same size as the 2.3H.O. TB..

On this one I just wanna do some simple bolt-ons... maybe the secret cams... they are very tempting..... but that would be the only thing ''major'' because anyway I got some oil leak on the cam towers... and timing chain cover...

[kwhauck]

I say go for the 2.2 pulley, should put you in the 13-15psi range....

[Th0r]

That's why I did secret cams. Figured since I had to reseal my cam tower seals I might as well swap cams while I had it cracked open.:lol:

somebody needs a red bull.....

OR NOS!!!!!!!!!!!!!!!! lol

the track I go to has a .499 red light, .500 green. 1.xxx is god awful. But considering the clock on the rest of the stuff doesn't start until you start moving, that is a decent quarter. and I'm sure you can do much better on the 60ft if you launch better. I'd have to look at my old slips, but I'm pretty sure I had 1.8?? for the 60 ft...NA.

[kwhauck]

but I'm pretty sure I had 1.8?? for the 60 ft...NA.

;) 1.8 i don't think so, especially not N/A

[spyhunter]

i've had 1.8 60ft times, & that was on slicks. With wheel time I'm sure I could've gotten down to 1.6-1.7

how many runs did you get on the track?

get thicker rubber, battery in the trunk under the hood no care, 2.5ich exhaust, smaller pulley, tune, meth injection.... you'll run better for sure. But just so you know that s/c is too small to do any real work on the dragstrip.

My opinion is sell the s/c and slap together a simple t3/t4 setup, or a tasty GT30 garrett. Tune it and if you don't hit a mid to low 13 out of the box we punch you.

[guiguilandry]

I appreciate all your opinions guys, but really I won't do any extensive work on that car because it is my daily driver I keep most of my money for my 3800 s/c one... so I won't go in a turbo setup... I'll upgrade what I need to repair first ( next things on the list are control arm bushing and front and rear tranny mount, they are pretty shot).
I can't do burnout because I only have 3/32 left on my radial t/a and I want to keep them for the whole summer... and that car isn't powerful enough fot my mickey thompson 8,5's...
Maybe If I can later I'll buy some azenis for the front, i'm on 215/60R15's...

Soo if anybody got secret cams, a meth or a nitrous kit that would be selling for cheap, I'm definatly interested..

And Albino... At this track too at 0.499 it's a redlight and I rev it to 2500 maybe before I drop the clutch, like that there is not too much wheel slips and there is always that guy that's putting water on the track for burnout... but like stated before I don't do burnout so my tires get wet at the start

Also what are the company that do the pulley for the m45.. looks like the pulley for the m62 will fit perfectly

[guiguilandry]

so my choice is made... now that the group buy for the swaybars has failed i'll get the money toward a hptuner on mpracing... but does anybody know the difference between the standard vcm suite and the pro vcm suite version... and can I tune with a wideband on the standard one... because if I can I won't need the pro version

and for the ld9 and ecotec crowd.. who makes the pulley for the mp45 I need a 2.7 one badly because once i'll get the hptuner... i won't be able to wait too long to tune it with the pulley...

Do I need colder spark plug at 9-10psi..... and do i need a shorter belt....

if anybody see a good deal for the secret cams too, I'm still interested... i never repaired my oil leak from the cam towers....

[[ion] C2]

I've always used the standard one and used a wideband. The pro is an extra, unneeded cost.

Smoothflow for pulleys.

NGK TR6 is all you need (same as the plugs that come in the kit originally, I use them at 18 psi too).

[guiguilandry]

cool thanks ion... and also a friend of mine gave me a msd dis2... i think that i'll use it

[[ion] C2]

for free? pass it along here

Shorter belt....or....

Possibly add a slightly bigger alternator pulley, or idler pulley, if your model allows it, I don't know the configuration on yours.

Depends on how small diameter you go...

[guiguilandry]

well not gave me really but for now he let me use it because he don't have his eagle talon anymore, he's got a subaru now and he need a dis-4.. and if he sell it then i'll need to give him back.. but this won't happen because i think that he won't sell his talon engine and drivetrain... he's checking for a used dodge colt to make a drag dedicated car...

[guiguilandry]

OK people just to bring this back from the dead and give you some updates.... I now have a spec stage 3+ clutch, 42lbs injector, the secret cams, 2,5 straight stainless dual exit exhaust, a set of slick and my hptuner.... Waiting reply from Irondog for the much needed wideband (sent money 3 weeks ago) I still have to order the 2,6 pulley from smoothflow and to (maybe) install the meth kit...

Also I got a brand new paint job custom metallic dark blue on the car with a new windshield... (because of the vandalism, but the insurance didn't pay for all of it. I still had to get 2 grand out of my pocket plus of the 1900 that they paid, but the job is done right, new hood new rockers on both sides and new rear quarter)keep in mind the the bodyman is one of my good friends and only charged me 25/hr plus the cost for the parts... so 3900 is a real fair price for the job done

But I need my wideband !!! just to get it running at least

[AZFire316]

are the MP45s you guys are running Air>Water cooled as well? sorry if a lil off topic, but i was curious about it.

[guiguilandry]

no intercooling on the mp45... not like the m62 wich is better

[AZFire316]

Im runnin an MP62 on my Balt which uses a Air>Water based system which is why I ask, is it possible to install a system like that to an MP45?

[guiguilandry]

no the intake and blower are one piece.... it could be done, but need to find a way to insert laminova tubes into the intake and reseal it... plus all the rest of the setup...

way easyer to spray meth or nitrous to cool the intake charge

[AZFire316]

gotcha! thanks for the info.
