97 GSX/ Borg s259 ett/ e73 dyno results
 

Finally got her on the dyno and not one thing went wrong!!! My e85 was tested and it turned out to be e73. Would have made my goal of 500 awhp but the clutch was slipping since it is not broke in yet. But in all I was very happy with the results!!! Enjoy!!!

480 awhp/ 375 ft lbs

Made 561 awhp on the dyno jet setting.

Very nice! What PSI were you running?

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Dang, congrats. I'm sure you'll break 500 next time.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Nice, have fun with it now before the snow flys!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Full mod list please! Glad it worked out for ya, your car looks like it's running great!

Pffft, 480 is weak souce...




...my X made 481 :)


Seriously though, congrats! Hopefully the clutch is alright after all that beating, get it fully broken in and go have some fun with it! Looks like a really nice car!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

That is some power curve! It doesn't fall off at all. Must be super fun!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Wow, sweet numbers!

Here is the dyno sheet, it wouldn't let me post it last night for some reason but here it is.

Here is a link to my mods:

Congrats, how much boost?
Sounds like a nice ride.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

I don't see dyno sheet. Looks like great power for a pretty basic setup. What did it take to get the IX pistons onto the 6-bolt rods?

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

It was at 30 psi and it is the same modification to the rods to get the 2g pistons on the 6 bolt rods.

Here is the dyno sheet, wouldn't let me upload it before.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Very nice man. I'm about to pick up a S256. I'm shooting for about 450.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Maybe Shane can chime in, but that appears to spool similar to a 35r sized turbo.
That powerband is sweet congrats man, go run some 10s!!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Ya it may be a little slower than usual due to the t4 housing it is in, it's in a .84 AR divided t4 housing. Don't ask me why but the previous owner had it made for it.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Damn that sucks. I know a friend of mine uses a mitsu flanged S259

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Ya it does suck but I guess I know the housing wont choke the turbo down. I am also thinking about swapping an HX40 pro with a divided t4 housing and see how they compare.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Nice numbers! Glad there were no major issues and you're happy with it

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Kick ass numbers!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

I was thinking about this and found an old dyno plot from shane/mara's 'project salt collector'

http://www.mitsustyle.com/forums/showthread.php?t=18245

Overlay shows mara's SC61 outspooling this thing but the BW turbo kicks butt up top!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Thanks for the overlay!!! Yes I bet the t4 housing is slowing the spool down alot but helps out with the higher RPM as it doesn't choke out. I think if it had the smaller housing, it wouldn't be able to hold that power all the way to 9k like it does.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Very impressive numbers! I love the powerband!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

The bad topend on Mara's SC61 had to do with the intake pipe in front of the turbo. This is after fixing the intake problem and some other changes( http://www.mitsustyle.com/forums/att...2&d=1285892300 ), but a better comparison of the turbo potential, it wasn't the SC61s fault for the old bad powerband.

His divided T4 housing should help spoolup a decent amount, but his exhaust manifold runners are on the big side and his cam has no low end, so those are probably hurting his spool up. You can have the same turbo on the same size motor spool 1500 RPMs different from one car to another depending on things like exhaust manifold, cams, intake manifold, cam gear settings, fuel used, etc.

His clutch slipped bad enough for the RPMs to shoot to revlimiter a couple times, so we had to keep the boost/power down some.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

hmm that SC61 looks so good.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Thanks for the info Shane and again thanks on the killer tune. I may swap the cams out for some kelford 272's and see if I can pull some vacuum/gain some spool time. Next time the clutch should be broke in so we can push the turbo to it's limits!!! And I don't feel that the spool is too bad considering it pulls so hard all the way to 9k without peeling off.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Very nice numbers for a 59mm turbo! Better clutch and more boost, and you should be in the 500's!

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

Well the clutch is a South Bend SS-OFE Stage 4 so I just think it needs to be broke in along with the flywheel. Then the psi will increase so so will the awhp.

Re: 97 GSX/ Borg s259 ett/ e73 dyno results
 

An overlay of Shane's fixed setup, and this would be cool. These are about the kind of numbers I was hoping for with my old 1g.
