still doubting this size turbo...lol

 

Parish ran a 76mm on his 408 at first. Search this site for that info. It was intierally too small for big power

 

That turbo you have will support about 1100rwhp.Do you plan on making more than that?

 

I would like to see that turbo making 1100rwhp.I just don't think its going to happen especially on a 408.

 

A 70mm will make close to 1000rwhp,76 has made more than 1200rwhp and his turbo is bigger than most....

It flows the air so it can make the power.

I think all should go to Grand National sites and do a bit of reading before anymore replies on xx turbo not making power.....

 

The much smaller GN motor will almost always make more power on a given compressor.They are two different animals.That being said I would like a link to any engine making 1100rwhp with a 78.I am not being a smartass jus really curious to read about the setup you speak of.

 

i am wanting to make around 750-800rwhp through a 4l80e
and want it to pull to atleast 6000rpm.... do i need to go to a 1.15 a/r???
will this turbo put me in my goal range?
