Yeah I agree installer error for the most part. I was just trying to make a point to the person that said they are problematic that that is the one and only complaint I have ever heard, nothing serious.

 

there are a couple of guys on another forum that have had bearing failures but with how many that are in use your going to get a a few bad units

 

i had bearing failure on my m62 ( why i now have a tvs )

 

i wasnt talking about a tvs, i was talking about ls4 throttle body, im running a tvs and a 2.7

 

ok, well its a cheap part i will buy and try out for myself

 

my bad... how do you like the 2.7? im waiting for delivery of my 2.5

 

You guys and your damn man pulleys lol

 

hey josh i pm u i looking to get a tvs get back to me

 

i like it, it brought back some low end torque, im still undecided on if i will keep it or not, it definatly needs a slight roll back on timing. ( can only get 23/24 into it without knock). 2.5 is brave, thats brave 27+psi haha

 

Whos running meth with their TVS? What kind of mixture are you running?

 

i am, 100% meth 7gph

 

im running a mix for no reason... ill prob be running 100% soon

 

You're guys temps aren't crazy high with no water? I know a TVS is much more efficent than the M62 but what kind of temps do you guys see after a pull?

 

I see 160--165 tops after a couple pulls in 95F+ hot/humid weather, but it falls right back down. On a nice day it doesn't go past 140 unless I really abuse it.

 

^^^ isnt that pretty high iat's nfor a 3.1pulley??

 

2.9, and that is peak IAT2. It drops off very quickly.

*those are pre-griffin numbers. I haven't datalogged my own car in months. lol

 

no meth my temps usually get around 135-140 after a 2-3 pull on a 70 degree day. Saw 160 once after a 30-130 pull on a 80 degree day with nothing but an incorrectly plumbed cobra h/e.

 

on a 2.9 i would see 145-150 after a pull, hasnt seemed to change much on the 2.7 on the tvs, but it was colder out by the time i got it installed, i have it so the car wont pull timing unless 150 is reached as soon as i go wot it starts cooling usually at the track as it heat soaks when im waiting in line

 

with 2.8 im running a few degrees below ambient after a few runs with meth. without it im only 10 or so degrees above

 

Wow good to know. I plan on going TVS just unsure when. If the right price on one came up i'd jump on it. Unfortunatly up here in Canada we don't have E85 so i gotta stick with meth in the mean time.

 

meth is fine, just go with as large of nozzle you can without issues and push your cars timing, run 100% for octane value

 

Yeah if you cant run E85 a 7gph or so spraying 100% meth will be the next best thing.

 

Are you on stock internals? what about pnp head?

 

Yep on stock internals for now. Have a ported head going on over this winter though!

 

Running no watermeth and IAT's dont go above 120 with a TVS 2.9 and to the E85 M62 guy I am making 310/267... GOD I need to just suck it up and buy the smaller nozzles.
