What would we do without the eagle-eyed Rennlisters like you.

Perhaps you should write the folks at Mozilla and have them tweak their automatic spell check/spell correction algorithm so that errors such as this can be caught before someone presses the “submit” button (which is not really pressed, but is invoked by pressing the enter key).

Wow.

I just replaced my Lindsey Racing Super 75 with a Garett GT30R, double ball bearing w/0.63 housing. The Garrett brings on the boost about 500 rpms sooner than the LR 75 and is more responsive. On a DynoJet with 17 psi we pulled 350 RWHP and 300 RWTQ. 17 psi was only achieved above 6000 rpms. The shop told me that I need to replace my manual boost controller with an electronic boost controller to reach and hold the 17 psi earlier in the rpm range. This upgrade is scheduled for next week. We will have to re-tune after the upgrade. Once upgraded, I will run 16 psi max boost for safety.

The Garrett definately improved drivability and this turbo appears to be a good fit for the 2.5L. If anyone is interested, I will post the dyno charts after we retune with the EBC.

Sorry man. I was just having some fun.

porshhhh951

Yes please do so that would be great.
no problem dude. Im just giving you guys crap. What I can't have any fun either???

I'll also have dyno charts in the coming weeks from the same gt30r kit for a stealth setup. Im curious to see the difference's =)

Here's a dyno of one of my old 951 with a K27/6:

Here's another... but the dyno broke on the 2nd pull which is why the power dropped off:

this is a very informative thread...best one in a long time.

Does anyone have pictures or a way to determine if a 27/6 has the 7200 compressor?

shaheed

dunno where you came up with this from, max boost on my k27/8 is set at 15psi and it hits that at 3500psi, not as quick as some modern turbos but certainly not 4000-4400. a number of rennlisters have run against my car, and seen it on the dyno as well, i'm sure they can vouch for it not being laggy.

jasonlp

It always depends on the money, what else you got on there?

shaheed

very little really, stock internals, EBC, MAF with vitesse software and test pipe.

jasonlp

Those mods help spool up, my numbers aren't so crazy if it's a stock car with a 27/8

Jeremy Himsel

IMHO you don't have any experience with a K27 on a 951. A K27 that doesn't see full boost until 400 - 4400 is on a motor with snapped rings or a huge header crack. Or both as I've seen.

A 27/6 on a car with a decent tune will see 15psi by 3200 rpm's. Only a couple hunderd RPM's off my Garrett turbo.

I do however, speak from experience.

jasonlp

nope I don't. My experiences have been with k26/6 k26/8 and new comer gt30r the rest comes from here say on rennlist and people which is what helped me choose garrett
