Had the opportunity to tune a customer's stock-block GSR EG today. Here's the results.



406whp / 276wtq @ 14psi
E85 fuel

The setup is as follows:

Stock internal USDM GSR
ARP head studs
Blox intake manifold
eBay ramhorn manifold
Precision SC61
Precision 600hp intercooler
3" downpipe (open)
RC1000's

Tuned on Neptune

For being a super cheap setup, this car performed very nicely.

First off...


2nd.
You should read the articles available on E85. They don't have as many BTUs as even pump gas, so 55 gallons would last half the time as 55 gallons of 93 octane.

Lastly
You're in Kansas. That stuff should be EVERYWHERE. Perhaps it was just in Jackson/Johnson counties (East of Topeka) that it is readily available.

Hows that boost curve look?

about how long do you think it'll hold? and a question for you guys, when yall throw headstuds on a motor that's never been cracked open do yall shave the head down or anything? or just buy a new headgasket and hope for the best?

boostedEF91

IMO. If motors never been taken apart and has never has got hot.. there shouldn't be a need to mill the head. new head-gasket and your set.. another way that worked for me before is just put one head-stud in at a time without removing the head. once all are in just torque all to spec.

D-Rob

Wastegate opens at 11psi and creeps to 14psi up top. Hence the super-flat torque curve.

It had just a single in-tank Walbro 255lhp pump and RC 1000cc's.

Nice work, Derek.

D-Rob

Thanks, James.

This was actually the second time I have tuned this car. It was here about a week ago, but I sent it home early, as the manifold gasket blew out halfway through the session.

And actually, now that it's been mentioned, I totally forgot to add that it does have ITR cams as well.

I was asking if he could import it not me I have as much E85 around me as I want who cares how long E85 last its a hell of alot better for power gains than 91 not to mention cheaper than 91.

I am sorry you dont like my preferanc eto use caps lock, but thats just me HOMIE.

sanman000719

I also have A BP headquarters near me as well where i can get what I want, and still love the "CORN"

HRTuning

Ouch! Well it held this time and produced great results.

D-Rob

Yeah, the customer did not have any more than four exhaust manifold bolts holding the entire thing on at that point.

- Derek

HRTuning

Can't be doing that!
