Customer greddy dyno plot...
 

Can anyone point me in the direction of or post up a greddy kit dyno? I am trying to decide between the greddy and the forthcoming JR SC kit. For a while I was dead set on a turbo and now I am not so sure so I would like to get the two graphs up side by side to make my decision.

I am particularly interested in seeing the plot from someone who has installed one of the more recent log manifold kits if possible.

I tried a search but couldn't find much so any help would be great :)

PS, I couldnt find a plot on greddy's site... how can they expect to sell the things without a bit more info than a price and a picture?? :ponder:

There is a dyno plot within the last 3 pages of FI called something like "greddy turbo dyno" and its about 20 pages...you can't miss it.

I haven't seen any graphs with the new log manifold.
It seems people with Greddy kits dont post their dyno graphs. (besides the two guys on here that worked with greddy)

here's one of my customer's dynojet run. it was a bit hot and by the second run it was heat soaking so the power went down. so this is the first pull.

I don't work for Greddy, and I have posted these in several different threads. My first tubular manifold cracked, so all of these were taken with the cast manifold replacement. My smoothest curve was my lowest number, but that had to do with poor traction on the dyno due to my brand new snow tires. The first two are from a dyno dynamics and the last two are from a dynojet and temps almost 30 degrees higher with less airflow than the dyno dynamics.

I have also been waiting for others to post their graphs, but nobody other than Will Chinlee and Chris Lum has ever posted (as far as I can tell).

I will post yet again this spring when I go back for fine tuning after I change my cat and put my summer tires back on.

Great, that is just what I am after...

The car has been running almost perfectly for over a month now since my last tune. I have had no significant issues, but I did decide to take my car in for a valve adjustment because it had been awhile since my last one. The mechanic told me they were pretty far out of spec before he worked his magic. I should be making a a little more power now than in the graphs above, but I'll find out for sure in April.

Bottom line is I'd do it all over again given the choice. My goals were always 80-100 additional hp and more torque in a car I'd drive year round. The coolest thing about the car right now is how easy it is to take off from a light. It just effortlessly spools up and leaps off the line. I know its not going to scare anybody at WOT and its not that loud, but its just fine for me. When I finally get the GT-R in a couple of years, I'm still going to keep my wonderful little car. You can't drop the top in a GT-R.

The only thing that makes me consider going with the Kraftwerks supercharger instead of the greddy kit, is greddy's failure to make it a true bolt on turbo kit. If I intend to have a turbo kit that needs to be tuned for it to run correctly, then I'd go with something more serious like an Inline pro setup for not a lot more.

Just curious, where is Greddy's failures?
