Inconel is tough stuff. BTW Inconel is a trademarked name for high nickel content stainless steel, and the majority of high quality turbine wheels are made with similar material.

 

Here you go guys.

7064 Kelford 272 cams syvecs S6 2.3 ltr Magnus inlet. 98 Ron Fuel.

Spool looks late due to cam timing, almost 1000 rpm later than the 7163 with 264 cams. It could go back on the dyno week beginning 16th to move the power curve left maybe 400rpm.

Dyno temps on the day were really hot which is why the power dropped off at the top end. Currently the core is rated to 550hp max but really needs to be replaced with a 700bhp rated core.

FYI i have been trying to achieve a 500/500 hp car with a flat torque curve till redline.





As a comparison - 7064 Kelford 264 cams Link G4+ 2.3 ltr Magnus inlet. 98 Ron Fuel.

 

Looks great, especially for the boost level. One comment I have is that a flat torque curve of 500 ft-lbs would produce a lot more than 500 whp at redline.

 

You lost 30lb-ft at 3000rpm (was 180, now 150),
You lost 100lb-ft at 3500rpm, (was 340, now 240),
You lost 70lb-ft at 4000rpm, (was 470, now 400),

Than its gains,
You gained 40lb-ft at 4500rpm (was 490, now 530)

We generally all think you should be able to improve spool: its a 2.3.
Issue is that dyno's can be run in many modes, so that is why you should be testing on the road.

Test it on the road, let us know how it behaves/spools on the road.
There is always 7670 in worst case.

 

And Dastek is known for showing very big numbers...

 

Here's my recent setup on a stock block on 92 oct:

7670 EWG 1.05 ar
ETS twin scroll kit
ETS 3" intercooler
Walbro 255
FIC 1100
GSC S1
Stock intake manifold and throttle body

Thanks to the guys at English Racing and ETS!

 

Surprised by 7670 moderate power and somewhat laggy spool

This power is in line with HKS7460, BBK-Full, and FP Green.

I would have expected full spool by 4000-4100rpm, and 450whp, at 25psi on top.

 

I was expecting 450 whp as well but I'm anticipating a built block in the near future. For now I'm happy with how it feels on the road.

 

The 7670 has never performed particularly well on our 2.0. Imo, the results don't justify the huge cost increase over running a 71HTA.

 

I have to disagree with Nemsin, 7670 not working well on 2.0:
I personally enjoyed an E9 with basic built block (people have pushed stock blocks just as hard and harder, so this was nothing un-attainable to the OP)

The car was built recently by Speedelement in San Jose,
E9 2.0 with Full Race EFR7670 1.05 AR
Trick is it was on E85.

Oh my GOD, this was simply stupid, stupid responsive, and stupid fast.
I have fast cars, so am not Prius driver never driven anything like Evo.

Full boost by 3600rpm, tuned to 26psi on Dynojet, it was pushing low 500's.
I have to check the dyno sheets/data I have somewhere.

It eventually made 600whp circa at 34psi..on 2.0 on E85 street tune.

But at 26psi at making low 500's it was absolute mad crazy car already.
On 92 pump 450whp...it should be plenty rapid, and hopefully full boost by 3700-3800rpm.

We'll watch this space for more.

 

I would be seriously inclined to believe the BW chra would last longer. Stock chra turbos seem to have a weak spot after having 3, to serious abuse and in one case no perceived abuse. While we aren't moving to borg warner , I think the gains are what you anticipate or see on the dyno, but the benefits are far reaching.

 

OwenDevelopments offers a BB upgrade to the 71HTA. Its just my opinion, but I have yet to see a 7670 pump gas dyno that impresses me. Most turbos look good on E85 at 34psi lol.

 

I have a EVO RS2 Tommi Mac with a Mivec 2.2 Nitto LR on E85, I am going IWG 7670 TS so assume will be making full boost at approx same 3600 just less top end ?

 

I think that is a good assumption.

 

Thanks

AT any ideas what other mods the IX had to achieve these results eg exhaust size, 3" or 3.5" stock intake manifold etc.
