I saw posted in a Import Tuner Magazine that the Greddy turbo kit dyno'd on a GSR only 220 or so to the wheel's while the Drag III kit put down 280 something. Granted the Greddy kit had lower boost by 2psi, but can 2psi make that much of a difference. I know that the Greddy kit comes with an 18G opposed to the T3/TO4 of the Drag III kit. What am I to expect out of 6 or 7 psi at the track on the Greddy kit and what kind of horsepower numbers do you think I should be seeing? Also, if anyone has pics of a Greddy kit on there car, can you post them please, I would like to see the finished product.

Greddy is reliable but wont net you the hp that RevHard or Drag will.....I would go RevHrad stage 2 if I were you but dont get me wrong Greddy is still good

there's a guy on this site with stock greddy kit + hyper exhaust (not big piping) and hes running 13.7 in the 1/4 with nitto's

the thing that's deceiving about the drag3/revhard numbers compared to the greddy is that the "280" hp you see is at like 8000 rpm. most of greddy's power is in the midrange...

what car did that guy with the greddy kit have?? the one that ran 13.7
And i was thinking of getting the drag 3 kit this spring but i'm might consider a greddy if its really true that the drag kit only makes its peak HP at 8000rpm and the greddy makes its power at lower revs

he has a gsr..i think his name is 'boostkillz'

OMG, I love it on that GSR. I have a Comptech exhaust. Just liked the stealth look from behind. You can't tell about the stealth look with a big front mount though. How much tuning am I looking at to do here. By myself or at the dyno?

Hey whats up man, As far as the greddy kit goes I have no regret of purchasing this kit, others would of course say different being biased. Anyhow as far as power I just dynoed my car a week ago and got 214hp and 165 to the wheels basically, in hot *** weather. This was on this setup: greddy kit at 7.8 psi using 310's w/bluebox, fabricated new downpipe of 2.5" to replace greddy dp, no cat, and hyper exhaust as immortal said, thin piping a.k.a. POS soon to go out for a custom 3" at stock timing using NGK's. Not bad considering what I have done for the car and dynoed on 17" wheels(small difference from stock wheelsbut still a difference) and got a best of 13.7@102 on drag radials for a best time so far. Average times were 13.9 14.0 at 100 or 101. By the way here is a thread I posted about a week ago showing dyno graphs..The first link I posted in the thread of my graph shows air/fuel ratio with a wideband, running rich so if I could lean it out I could net more power you need to copy and paste it to your browser to check it out.. this link to the thread has my hp and torque curve that DB8gsr posted for me. https://honda-tech.com/zerothread?id=69247 . Hope this helped ya man and feel free to ask questions.

Why is it that the Drag III kit makes a whole lot more power. The bigger turbo can't make that big of a difference

boost killz

Mainly that is the only reason why.. bigger housing and turbine=more airflow at same psi. but again those are peak numbers, where greddy has a very sweet low end and midrange with no lag what so ever.If you care to hear it this post has an audio file i made with laptop and microphone in the engine. https://honda-tech.com/zerothread?id=70435

SagaGSR

two words. open loop

immortal

sounds exactly like my bov.....my exhaust isnt like that though

00 Si

What kind of exhaust is that anyway? I hope mine sounds like that. I have a comptech and it is really quiet so i don't know if it will.

VR_GS-R

basically i want to know if the greddy kit will give me the times i want which would be a consistant run of 12's all day and i want to know if the greddy will help do it. I don't mind getting internals and lowering compression but i want my car to hit the 12's on the quarter mile so will the Greddy kit do it for me. Because if i must get drag i think i will but i really don't want an illeagel turbo in my car. Please help me decide.

immortal

eclipses upgrade to the 18g and run 20+ psi on it. it'll get you 12's and more if you boost that much.

DoctorBob

I don't think anyone got around to answering your question so here's a quick summary: turbos help the engine make torque. The efficiency profile of the turbo determines where in the rev range it makes the most additional torque (Greddy mid-range, big turbos high end).

Power = (torque * rpm) / 5252. So, if a system makes big torque at high revs than one that makes big torque at mid revs, it looks like a HUGE power difference.

But remember, assuming identical charge temps, 7psi = 7psi no matter what the system (theoretical max torque increase of approx 50%).

We just got do with a greddy kit last night. I like it alot. Just needs a little more boost.

00 Si

Needs more boost? What psi are you running. Just wondering.

ATYPR

It's not on my car, it's on a customers. It's at stock settings for now.

The Greddy kit in a GSR will get you 12's all day if your running slicks. I have it in my GSR and ran a 12.3@111.11MPH at Englishtown. Of course that was at 13psi and no exhaust and 108 octane. Car weighed in at 2800LBS. I used M/H 22x8x13 slicks mounted on axis (Lenso) drag rims. As for internals, all I have done is F-max Head gasket, ARP head studs and Nuformz block gaurd, still have AC and power steering. Nothing else done to the kit, meaning stock downpipe!! Plus I drive this everyday and drive it from Boston to New Jersey for some of the races and than drive it back. No problems with the kit whatsoever. That's my input on the Greddy kit.

00 Si

I didn't know that you could order just the head gasket from F-Max, how much was it?

Hey boost killz, I just heard your sound file of your car with the greddy kit. It sounds really nice. I was just wondering which bov you are you using with the kit. I know that one doesn't come with the kit, so let me know what kind it is. It sounds great. Thanks for your help.

jinxproof99

order your headgasket from inline pro @ 703-644-1788. good to over 20 lbs of boost!!

boost killz

Hey Jeff thanks for the compliment...I put the greddy type-s bov. Glad you liked the file

Does any1 know how much boost the internal wastegate can handle??

boost killz

Gmedalion, from what I have been told 16 max, anything higher is pushing the limits of the wastegate and turbo itself.
