I got the GReddy turbo kit almost 2 years ago and have been adding to it ever since. I believe the little turbo has finally hit its limit. My shop just finished up installing and configuring the Hondata Boost Solenoid and it is amazing! Final numbers = 300WHP 237TQ =)

It is running stock boost from the wastegate on gears 1-2, then 10 pounds for gears 3-5 and 8 pounds for 6th gear. The injector duty cycle never goes over 69% and its holds low 11's for the AFR under WOT.

My next move will be a larger turbo of course but for now it really moves and I have terrific traction so I"m pretty happy :vtec: On to the pics and numbers...

Setup:
-Hondata Boost Solenoid
-Hondata Flashpro: Tuned by Import Hot Rod Garage
-AEM Wideband
-Apexi Turbo Timer
-Competition Stage 2 Clutch & Flywheel
-Custom 3" Turbo-back Exhaust-Vibrant muffler
-Akita AK-1 Hypersilver
-Nitto Neo-Gen
-RC Injectors (750cc)
-TurboXS BOV - RFL
-Ingalls TQ Damper

those are some solid numbers right there. Those injectors are the right size for sure. Nice!

Nice job!

Congrats, looks great. Your AFR during WOT should be 13.1 or so IIRC

Negative ghost rider, WOT with boost is ideally 11.5 for pump gas.

Another member to hit 300 with the Greddy kit. Great Job.

using the magic recipet of:
3" turbo back exhaust
650 and bigger injenctors
FP
and 10psi of boost

thats a lot of good stuff.

For an N/A setup, 13.1 would be ideal but like Supa Ninja said mid 11's would be ideal for boost.

To OP, Nice numbers! Good list of mods you got there.

Thanks guys! I only got to this point from reading your posts and getting the inside scoop on what really works well with our cars. I have an amazing shop and tuner but even with that I still normally print out tips from you guys to help with any installs and tuning. 8thgen community rocks :dancing:

Awesome, these guys got the greddy all figured out.

You got that right, haha. Between you, Mike and Mucter, I have learned a great deal about correctly boosting these rides.

That looks like the perfect street setup, power doesnt mean a damn thing if you cant get it to the ground!

I've built it for the twisties and it is nearly perfect for it. I just need to upgrade the brakes and tweak the suspension a little. But other then that I can't complain =)

Looks good!

what ur psi at i dynoed on the dyno dynamics as well at 7.5 psi hitting 250.3 whp/195lbs/tq using the flashpro...

 

[David4687]

the 3" turbo back makes a world of difference.

I'm at 10 pounds on gears 3-5, 8 pounds for 6th and its at stock wastegate boost for 1st and 2nd.
To hit 300 with the GReddy kit(stock turbo) you need a killer tune, upgraded injectors, a boost controller or the HBS and as Nick stated a full 3" TBE.

 

[bmnorm2]

very nice setup!! looks perfect for the twisties lots of low rpm torque

curious why you reduced boost in 6th gear to 8??

 

[Supa Ninja]

putting too much of a load on 6th is really rough on the internals. mine is about 6psi, you really don't use 6th for racing just cruising.
