80mm vs. 64mm

The 80mm will have more lag (200rpms max)
The 80mm does eliminate compressor surge

I have not seen any outside dyno 80mm vs. 64mm other than what Scott tells me from FP. I believe that the 80mm will not produce anymore topend over the 64mm for one reason. The 80mm will produce more turbulence at higher engine speeds than the 64mm. For example: On my setup, trying to max out the stock turbo, Scott told me to put on a evo VIII compressor housing because it is a bit smaller than the IX. He said I would gain top end. Him and I talked about making me a prototype 80mm housing for my stock turbo but after much debate, we ruled out that we would lose power due to having a larger AR, that the turbo has to try and fulfill at a higher engine speed. Thus creating extra turbulence that the turbo doesn't need. I'm not sure that this will be the same case with a red. but I would like to see a 64mm vs 80mm dyno. I know TTP said that it doesn't produce any more power but I wonder how much it loses???

FP Black....? Does such exist, or are you just pulling my leg?

 

feel free to PM if you don't want to share it with the world. I have been considering this turbo and would like to get an idea of how it does. Raw data would be great.

 

thank you...it'd be nice to see some data on this turbo

 

It will soon

 

4500rpms is a bit high, isn't that around the same general rpms where a GT30r hits (assume same supporting mods)? I thought the whole idea behind the FP Red was to make a turbo that could flow the a substantial amount over stock, yet provide for a faster spool to hit full boost. Am I crazy, or have I been mistaken this whole time?

I had my mind made up on a Red, now I'm plain confused as to whether the Red is really worth it. From what I am reading, the Red is a serious contender to those looking for outright power from a stock appearing turbo, but again I am back to asking myself, "well why not buy a GT30r?". I can only assume that since the FP turbo hooks up to a IX the same way a stock IX turbo does, this along with running all the stock parts is why the FP Red exists? Or maybe I'm crazy.

 

Why does God make me suffer? Why doesn't money just fall out my azz? Why....

Green, White, Red, now Black.......where's Blue, and yellow, and all the other colors of the rainbow?

 

Can the stock intake and/or all aftermarket intake kits be used with the 73HTA? Or do you need a custom intake pipe for the turbo?
Or is this only if you choose to use the 80mm surge port?

Can't wait to see how this stacks up against a BBK Full!!

 

u just need a different coupler

 

Bump for dyno graphs!

 

just wrapped up the tune, getting the data together tonight most likely

 

Can't wait.

 

Don't tease us Chris. Just post the damn data already.

 

making a thread now check out the dyno section
