Me not new, lol, New name. been gone long time. Got another lsj thought I stop back in but as REAPER HHAHAHAHA cus its scary like the car lol but thanks for looking out for me.

 

correct alot of factors, that would cause most peoples lsjs on this site to go bewn, all i mean to say is nitrous is not something to experiment with if one doesnt fully understand it, research, research, research. Then try it, say on a 2.9 or a stage two pulley, I hear the torque spike is intoxicating

 

O yeah, a true 150shot on my 01 cobra was enuff to sell the vortech setup. People would be like nitrous is cheating bla bla bla yet its ok to cheat on your girlfriends but not in a race hahaha, morals. Yes the trq from juice is like no other. If it wernt for gas prices and the distance i need to drive and lack of comfort, I still have the car just the grass is so much sweeter when you spank a v8 with a lil ol ecotec and still get 31 mpg's. plus even if I had a vette or viper or whatever in a few years I would get tired of it and try something diff to keep the joy from this hobby.

 

I know someone who ran 50 shot on a 2.7 pulley and sprayed meth...

regardless, anybody have some logs with iat2s on a 2.5 pulley.

 

I was referring to the nitrous on a 2.5, I konw someone that ran a 75 shot on a 2.5 with 100% methanol

 

I wouldnt run a 2.5" pulley w/o a ported head, but thats just me.

Your gains will prob be minimal w/o one, but I'm def. interested to see your results.

 

yea me to I would love to see a 2.6 or 2.7 pulley setup with just mabe a zzp ported head and tune. to me that should be a solid 290 or more and will be a great contender to the tvs pump gas setups for guys looking to stay with the m62. Why havent more people done this anyway but they will buy the tvs with the stock pulley and still not make more than 300whp. Mabe its to just say they have tvs.

 

These cars don't make power with pulleys that small. you lose power or it stays the same, risk goes up. If you had a dyno to play with you could swap pulleys and you'd see it.

 

Then why might y'all sell a pulley lower then a 2.9 if it doesn't make power? Doesn't that seem dumb to sell something that does nothing? Don't mind me I am just a passer by.

 

i did buy the zzp 2.5" pulley before my research, maybe i might just return it. but i am temped to just put it on.

 

1/2 the parts in this market don't do anything. We meet a consumer demand. not to mention there are other applications and crank pulley changes that would merit a pulley that small.

 

Okay I just wanted to ask and see if you were going to respond to that.

 

More tq from what I've seen but not worth it.

 

There are quite a few guys on 2.6" or lower and I myself havent heard a single one wrecking an M62. I'm not saying there's noone out there but it's not a common thing. If you have the proper cooling mods i say run it. You can make some good torque with it. Something to try anyways. I may just have to do a back to back dyno pull with my 2.8" and 2.6" to see the gains.

 

You won't see any. Will probably lose power up top.

 

Its not so much that the smaller pulleys wreck the blowers, but more that they can pop engines due to the fact that the stock blower becomes a blowtorch with a pulley that small. I ran a 2.7 on E85 on stock blower after switching from a 2.8. It felt like there was more torque but the top end felt the same, but the intake temps went up. Now on the TVS and 2.9" I see similar temps on more boost just due to efficiency.

 

we are going to put a 2.5 on mine in the spring
currently for cooling i have meth, dual pass, fmhe, and we will also be porting the blower and throttle body before the 2.5 goes on, and retune of course.
and while the blower is off the car its going to be rebuilt.

 

Are you doing sleeves as well?

 

The torque is not worth the heat esp on stock head, the only reason I have a 2.6 on the is cause I got bored with making 16 psi on a 2.7

 

Frew you made 16psi on a 2.7 on a ported head? Thats weird to me since I only made 15.5 on a 2.7 on the stock head, but Im guessing elevation and climate has something to do with it.

 

Only if it blows. Ported head, dual valve springs larger valves Bates head studs and new head gasket and neutral balance shafts first

 

ebristol has the highest whp and wtq on this site with a 2.6" on a stock motor. Cant be that bad. Just sayin

 

Oh sweet man, should be a nice build.

He is also on E85

 

To be exact it was 16.33 psi@ 7400 rpms, there are so many factor that play in from exhaust size, air temps, elevation, etc its really hard to pin it down.

 

E makes a huge difference if I was on it I would be on a 2.5 ring all day
