Have the harrop tvs tuning a 2.8 on it just wondering if I should keep the. 2.8 or be able to drop to a smaller one so I have more boost but wanted to know if I drop down and still run nitrous if it will still be safe or should just stick with what I have? Basically asking what's the smallest pully I can run and still spray?

 

Sub'd. Also, glad I didn't click this at work....

 

What?

 

You labled this as NWS aka Not Work Safe.....

But I subbed. Just being an ass. Someone was bound to say it

 

My bad I changed it didn't mean to.

 

run as small as a pully u want just tune for it

 

If your on a stock motor the 2.8 is pushing it pretty well, on nitrous even to a low boost M62 car it wont live long

 

if its tuned for it will live long and prosper

 

bullshit... that much boost plus a 70+shot of no2 will not last long regardless of tuning for it on stock bottom end. unless your running on really high octane and have a really strong motor. I would not suggest it.

 

streetdreamz did a 100 shot on a harrop and a 2.8

 

oh thats true, and i know him well. and i know how long his car lasted... so if your looking for peak numbers and something that will last you a week then yes go for it.

 

his car lasted longer then a week

gm only rates the pistons at CRANK 300hp, running a 2.7 your prob already well above 320 to the wheels, long term thats questionable enough, through nitrous in the mix, it shortens your window even more, nitrous is much harder on internals than just cranking up the boost

 

blah blah blah grow a pair its been done and the car lived along time

 

Yea list of mod are clutch fly short throw intake full exhaust lsj3 heatexhanger snow performance water/meth 80injectors zex wet kit w. 75 shot and tvs w. 2.8 as of now just looking to see if its really worth dropping to 2.5 or witch one would be best suitable.

 

car lived along time thats true... his motor did not though. The guy is local don't try and bullshit me and everyone else on this site just to prove that your right.

 

Gonna have to chime in here...

Motor lasted just fine. One time I lifted the head and had to get new studs. Another time I tried to spray off the line and bogged and had a backfire in the manifold that broke the bypass flange and bent the flapper on the Harrop and blew the intake off the throttle body. Other than that, she loved it. I did have to stick with the 2.8 pulley on the 100 shot though. The 2.6 lifted the head even with ARP studs. On the boost gauge it hit close to 32psi even with a exhaust side ported head and full length header and 3" cut out. The next day I had some coolant pop out of the overflow.

 

well thank you for stepping in and clearing that up. still not completely perfect though. where have you been at man?

 

Sleeping mostly lol. Just took a hiatus from the game for a bit. Sold off all my cars. Now this year I have the bug again and went and bought me another redline that I'm restoring first, then making fast later.
