GheyrodX - bigger, fatter, gheyer!

[Kracka]

Some day I will do that for you. Maybe once the stock clutch goes and it's replaced with something a bit beefier.

EF2 ftw on your car. /pray new cover helps.

I agree fully. My previous EF2 is the better "ultimate street turbo" all things considered, but we'll see how the standard cover performs. If I can gain back half the spool lost then I think we'll have a viable contender. MAP has asked me to get it done so I'll be calling Cobb to get something on the calendar.

Cobb's power board, before & after:

15th ---> 13th

[Murlo26]

Those cars area all really close. I guess for good reason, stock block cars I am guessing.

[Kracka]

You can scan the QR codes, or just go to their online dyno database for all the info/details on each setup (since you probably can't scan the tiny on-screen codes).

What kind of gains do you think some cams would net you?

A lot Cobb keeps pushing me towards Kelford-B cams, but I keep pushing back fighting to keep my stock-like smoothness and drivability.


I'll have standard 3" compressor cover results on Saturday, December 22nd.

[evotuner]

are they planning to try this ef2.5 on the evo 8/9s?

[Kracka]

Depends on the results on the X, but if it's a solid performer and sells well, then yes.

Standard cover testing begins today. GheyrodX had a sleepover last night with some foxy Subaru bitches

I approve of your description of Subaru's as bitches

Good luck.

Nice! Looking forward to seeing this next week.

[Kracka]

Here are my latest results, these are with the standard 3" compressor cover rather than the 3" anti-surge cover. This seems to be the winning setup if you ask me; 200 RPM quicker spool, better response, more torque, nearly identical horsepower, and of course one less option to pay for



Driving impressions are great! No surge issues could be felt and it drove very nicely. Initial impressions are it drives just as smooth as the anti-surge version, but give me another few days to truly experience the turbo in more scenarios. Oddly enough, turbo intake noise is slightly more with the standard cover than with the anti-surge version.

My final verdict: Standard cover is the way to order this turbo. Save yourself a few bucks and enjoy the quicker spool/response times!

[scheides]

Badass! I was second-guessing this wheel combo but it looks pretty pimp now!

[Mark Leasure]

Looks like good results with the std cover. Nice power on 93 too.

[goodhart]

More power under almost the entire curve too! Nice!

It would be nice to see an over lay of the standard cover EF2.5 vs the EF2 once they get the database updated.

[Kracka]

Should be available next week.

[goodhart]

EF2 vs EF 2.5 standard cover:


Not sure which I like better, the extra low end grunt of the EF2 or the higher peak and top end of the EF2.5.

[Murlo26]

I'd still take the 2. On a more basic setup, aka no porting, I might go for the 2.5 but his setup is efficient so 2 all the way
