What we all really want to see are some 4G63 7163 dyno charts. So we can compare them against other established ~400whp charts.

 

I have a few charts- and one of the kits is being tuned at AMS Performance this week I believe-

I do have our test car- that was on stock cams, catted, bolt ons- with our kit on 93 octane- I will try to get that scanned and uploaded- maybe an overlay against for instance a bbk full/bbk-b

Just wanted to add some food for thought-

We did test the smaller 6758 turbo for BW- on our current setups and it simply made less power with an immeasurable spool change-

The most impressive thing has been the 7163 making 7670 power- due to its more modern configuration!

Also, do you have any data that shows this amazing transient response™ we have been hearing about?

 

I will be doing some more testing shortly- rolling speed/time/boost, etc to show things a little better-

Wait, what?
The only 7670 on an Evo 9 that I have seen was Eric (R/TErnie) car and he was making like 600 on a 2.2 4g64 and e85..
I thought the 7163 was more or less a 400whp turbo on a 2.0?

 

I was thinking about the 7670. My calculations based on the flowmap for my 2.2L Cosworth show it hitting 28psi at 3K and holding out till about 9K. Does anyone have any experience to confirm this?

 

R/TErnie's car is probably not the best example of "normal" 7670 4g63 results. Some other results have shown that at normal boost levels, the 7163 spools earlier than the 7670 and makes "nearly" as much power up top.

Here are some STI results http://blog.perrinperformance.com/bo...test-and-tune/

 

The 7163 is a new generation turbo- with MFT turbine etc- so its pretty potent in a small (gt30 size) package-

We have made 400+whp on our mustang dyno on EVERY evo X with the 7163, internally gated etc- we have been keeping them below 450/380 for sake of the stock bottom ends- cranked up- to say 30psi on E85 on a built block, would net probably 550whp on our dyno, 600 on a DJ-

Man, I like it! I'm REALLY excited to see what a good sized twin scroll will do on this thing on a the 4G now.
Thanks for putting in the work chad!

 

No worries- we wouldnt have gone down this path if we werent excited about it- the EVO X stuff has been awesome for us- we can't keep up!! the evo 8/9 is picking up (ironically we released it second)

here are some pics-

of a customer installed RBX EVO 8/9









we are revising the water lines for the wastegate! shorter and better angles!

Its a Hypertune manifold (the pics I posted are a sneak peak into their shop), new product in development to suit the smaller EWG EFR's (B1 & B2). I don't believe there is anything in the pipeline for IWG EFR's at this stage.


Entire manifold (flange, collector, runners) is 347 investment cast stainless, no steam pipe used here

 

LOL-

we would love to use inconel- but whose going to pay for it-

the reality is 304L is fine for these (non full motorsport) applications- and the value added collector when you are still welding individual bends to it- not casting the entire thing- doesnt make much sense to me-

The individual parts are available for sale, all the hard work has been done for you, why not shoot Pete @ Hyper an email and see for yourself why they use it?


Your kits are called 'RBX' (Racing Bred) but not recommended for motorsport??

 

Legit question Chad,

Are you saying it doesn't make much sense to you to have less parts to weld up?

I think they have the cast collector as you can't cast the entire manifold if you don't know what car or turbo it's going on.
Toxicfab also have one piece collectors except his are machined.

I'm not sure I understand the issue??

 

Thanks for keeping us updated with all of your developments. I'm looking forward to seeing some more results.
