Part 2 coming soon!

its gotten put together since my last post but i got a new race i want to win.

 

Have you checked you coils and all that? I'm still a bit shocked with your dyno chart....

curious for what part 2 is....

 

i replaced them bout 3k ago.

starting to piece together gt3701r kit im gunna run to the max

i plan on running 7 psi dd, 14 psi high and get rid of my catted pipe for a dual resonated piece.
ill deffinatly rework the ignition once i get closer, for fuel i plan on using 750 in the p2 550 in the secondaries and uncap a pair of stock injectors for p1.

honestly i would like to get as close to 400 as possible but the quirks will be inherent, i see people waiting to see what the 71r has to offer and some dont like the idea of doing what brettus is doing. i feel confident that i can do this in a reasonable amount of time and hope to start the 350 hp club.
if there is anything i left out that anyone thinks i should consider please post, im always looking to be a trailblazer than a follower.

 

/\ hmmmm . I'm a bit curious about what it is that i'm doing ?

 

maxed out the GReddy snail I believe is what he was refering to......

Have you considered a GTX3076R RXPLODE? Or are you trying to hunt down an already modified MM 71R?

 

/\ cuz having 300+ whp is such a drag. LOL

 

aim for 300 before you aim for 400.

 

i understand that this motor is a bit more picky about what it likes and doesnt but whats the fun in doing the standard? i was thinking bout an MM 71r but gtx does sound a bit more out of the box. i priced it out and it comes out to like 2200 for the gtx and all the hardware to bolt it up. specs:

Turbine
-Wheel: 60mm w/ 84 trim
-Housing: .82 ar

Compressor
-Wheel: 71mm w/ 56 trim
-Housing: .50 ar

with a 7psi wastegate, i also plan on running a ebc but havnt decided on what one, i would like to get something with a single stage (off/hi) setting.

 

haha I see your still in an argumentative mood from the "clutch discussion"

But yeah 300whp would suck that's why im sitting happy anywhere between 228-250 Whp right now.. cuz 300 WOULD be a drag ..... but you know what he was refering to, pushing the limits with the GReddy, not whp numbers.

I mean what would you rather do, hit 333whp with a maxed out inefficient upgraded GReddy or hit 333whp with at GT(X)307XR turbo for not an overly abundant amount of $$ more and have plenty of room to spare in hopes that in the future hitting 400whp won't be such a mystical number? Edit: not to mention spool up time is nearly the same with the BB turbo

To tell you the truth the OP already stated that he wants to push some boundaries and isn't scared to pop an engine; I'm all for it and wish you the best of luck, I hope things turn out good for you because I plan on following the same game plan you have going on... except aiming for a more reliably obtainable 350rwhp.

 

Oh and don't think I'm knocking on your set-up at all Brett, I envy what you've done. I am just trying to portray the mindset of the OP and how it relates to my future plans also

 

I'm installing mine this weekend with pre compressor water/meth injection...... I have the 20g upgrade already also

 

no worries man .

BTW - that 333 dyno WAS pretty much at the limit of what i can get out of my turbo but i only ran it there for a brief period - just to "push the boundaries" .
The last 2 yrs and 22,000 miles has been at around 300 and the setup has been perfectly reliable at that level. If people think "I don't want a perfectly reliable 300whp setup" then yes definitely .... Don't do what I am doing .

 

^ Haha Oh ya I've read all about the 333whp dyno. But by the time I'm ready to upgrade (not looking good since my alternator decided to take a dive...$$$$) that this time next year you will be telling me about how reliable a 350whp set-up is lol

Is a 7psi wastegate with EBC going to be enough for 400whp? I mean Brett you have a 7psi spring with your actuator arm modded and PRofec to hit 300 right? I know it is a completely different turbo and flow characteristics but it's still internal WG; wouldn't a bigger actuator be needed?

 

Sort of .
The way I have my set up , the BC does nothing after about 6500rpm . It's there just for fast spool up and low down torque.

Depends on the design of the actuator . That big *** one MM uses is actually a 7psi(ish) actuator .

Short answer .... Yes

 

oh I love the short answer when it makes me look like I know something about stuff

hmmm I might have to play around with my wastegate arm a bit then..... I was hoping the EBC would help me hold boost longer toward redline on top of low down torque.... I'd like to try and keep around 6.5 psi right to reline with a peak of around 9psi. Is the PRofec cabable of this without actuator arm mod?


RXP hows the sourcing of the Garrett coming along?

 

My Stock actuator gave me around 4.5 psi at redline and the EBC increased that by a whopping 0.5-1 psi . With supply taken pre throttle rather than at turbo you may do a little better than that .
If you had an EBC that increased DC as rpm got higher you could do a lot better than that without the need to change the actuator.

 

^ guess I'll be getting my hands on that wastegate arm haha
