1500 miles on the turbos/exhaust.

Powerkit inculdes...well go to www.evoms.com and checkout the stage4Gt package.

Accepting serious offers.

Thanks,

Ryan,

Let me take the first guess, selling the GT2, and getting a 360 (CS or Spyder)?

Oh yeah, bump.

David

 

Uh, I would never do that.

Just keeping the GT2 stock. GT2 to a 360 is 2 steps back.

 

Oh. I thought I recalled you either ordering or contemplating ordering a 360 Spyder a little while ago. I just assumed that Watt's and ESK's recent posts pushed you over the edge.

Anyway, can't go wrong with a GT2 in any form. Why have you decided to revert back to stock? Are you just gonna mod the heck out of the Turbo and keep the GT2 as designed. How is the trubo coming along (Motons, etc.)? Just a reminder, post a comparison of it and the GT2 once you get the Turbo suspension done. Good luck, and sorry to get off-topic.

David

 

Shank, i highly recommend Stage IV on the GT2. Much less of a headache than the GT, all the major factory parts stay in tact, but the car is much more fun to drive.

 

I am most likely going with the RUF Nardo Package. Stage 4 might be worth the thought too............still deciding. Need to start over.

Rs

 

definitely take a look at it. if you have any questions about it let me know.

 

which kit is the RUF nardo?? the 590 oone??
The Ruff550 and GIAC level 4 pulled the same numbers on the dyno FYI - KPV and Sean took their cars on the same days and the curves almost OVERLAP!! on had a few more ponies the other a few more lb.ft of torque....

 

Ruf Nardo is the 590hp one, and it is the one to get, although I would imagine the power will be somewhat difficult to modulate properly when on a racetrack.

At 50,000 Euro for the engine work alone + transport costs to Germany, it is not a cheap proposition by any means.

 

Shank, instead of starting over completely, have you checked with Evo/Imagine first as to what's going on with your Stage IV-GT setup?

From other people's posts about the AF ratios of the Stage IV and GT, the kit appears to be running way too rich for whatever reason. Perhaps those guys can do more R&D, and get the kit right... I mean, your car is almost there, seems to need just some tuning refinement, right? Or am I missing something?

I remember when I first was researching Upsolute, everybody was say'n it doesn't have as much R&D as GIAC... yeah right. Seems like it's the GIAC/EVO kits that people seem to be having problems with.

They're so close already with perfecting the kit, I don't see why they don't go the last mile and finish what they started... just spend more time fine tuning the damn ECU. Somebody posted AF ratios of 9 or 10... that's a complete joke. Whoever tuned it with those parameters must have been on weed and keg'n it that night. It's either mis-programming, or something is wrong with the car. I understand wanting slightly rich conditions for protection, but AF ratios of 9~10 are excessive.

Maybe you can get Evo/Imagine to tune your car again before giving up? Just a thought...

 

Mine is in the low 12s high 11s on a stage 4....I have yet to hear of problems with level 4s, all the problems seem to be with the 4GTs...

 

you have to remember that 4GT is really a super high performance tuning package. To compare it to Upsolute is a joke. The bottom line is that anything over 600hp in these cars and you're going to have lots of issues to deal with. The Stage 4 at 600hp is as proven as they come and solid as a rock.

Why don't you read my post again before spewing out of your ***.

I didn't compare performance numbers between the two. Merely that we seem to be seeing instances of a lack of thorough tuning of the Stage IV GT packages. How many people are running Upsolute that is having problems such as 9 or 10 AF, stumbling, power drops, etc?

My Upsolute from day one has been flawless. Dyno graphs show AF ratios to be rock solid around 12. I've raced Stage IV GT first hand to a dead even heat. It was only after further tuning fixes that it was able to pull on me. Now, if you are paying $15~20K, why was tuning not optimized or even properly carried out prior to delivery?

I'm not comparing numbers between the two... only that R&D was obviously superior in terms of some of the mappings of the Upsolute vs. Stage IV GT that resulted in non-optimized condition of the Stage IV GT, which in turn resulted in an even run.

Obviously, I'd expect a $15~20k upgrade to kill my $500 chip... or so you'd think. This is speaking from experience of a personal friend with a Stave IV GT as well as feedback from the shootout as well as posts on this forum. Don't believe me, do a search.

You write that "The bottom line is that anything over 600hp in these cars and you're going to have lots of issues to deal with." Well, that's certainly correct if the kit wasn't properly designed and executed. I can tell you that I've been around many 700~1000HP Supra buildups with piggy back computers that had less programming issues right out of the box than the Stage IV GT.

You also write "The Stage 4 at 600hp is as proven as they come and solid as a rock." Really... then explain why one of the local guys ran neck to neck with the Stage IV GT and me... and why additionally tuning had to be addressed to get it up to spec? I was there... were you?

The bottom line is, there's been instances of Stage IV GT (and IV) that hasn't been performing up to hp claims. You can take a poll of people who have had issues with IV and IVGT setups if you'd like. Additionally, AF ratios of 9 or 10 is a joke. Now, which part do you not agree with?

If you want to talk compressor maps, turbine maps, fuel mappings, af ratios, ign maps, efficiencies, etc, I'm game. But your blanket statements are absolutely false and unsubstantiated.

 

FWIW We have never had a problem with any of the original IVs. These will be the kits that run the K24s not the Garrets. I have so many of these kits out there and dyno to support it. Also for what it is worth We have been relooking at the program. We have tested several changes from Kansas City and AZ and are looking into the Ryan's newly developed issue. Finally do you really think that if there was any known issue we ever would have released a kit. That is the most disturbing part to me that the accusations of kit being released with ill intentions. I nor Todd have ever screwed anyone and sure as heck would not try to slide something past anyone. That would imply that my disposition as well as Todd's is only about the dollar. Which is so far from the truth. I spend my morning on the National PCA site as a National Tach Advisor offering free questions and help, I then float through 4 different web boards helping with questions and problems, then lastly go to my small board and then my personal emails and offer more free advice and help. If something has gone astray with the program then it will be fixed. I as well as Todd have spent the last week testing and calling every GT owner to gain a better picture. We all were happy with the last trip to Chicago.

 

I agree with Stephen. These guys love this stuff as much as all of us. They are car crazy nuts like us and actually OWN and drive these same set ups. There's no reason for them to release something that doesn't work right etc... They use what the preach/sell.

I should have been more clear about my programming as I'm the one mentioned that I have the high 9 low 10 afr's. The GTR kit is not what I have. I have custom GIAC programming and different turbos, which were not originally designed to go together. The main reason is that Todd/Stephen were kind enough to step in and at least allow my car to run at all for the shoot out. Todd/Stephen didn't have to do that My car was in a sorry state in that I had big bad *** turbos and no software. If it had not been for them trying to match the software with my custom ZC turbos I'd be running 1.7 bar on the Upsolute still with the throttle body closing at 1.3 bar. As it is now, yes my AFRs are very rich but at least it's safe and I know that as with any other experimental turbo set up it's "work-in-progress".

I think we all know that Stephen, Todd and Garrett are great people that stand behind their products. The Stage IV GTR kit is bloody awesome on the TT. The GT2 obviously just needs a few more tweaks. There's no packadge out there that can match it for being a bolt on high HP set up.

I only have myself to blame for my AFRs. I wanted to do something different/special with Kevin's turbos. I thought I could get it to work with the Usolute stuff and I was wrong. The price I'm paying for being experimental is to run rich for now

Because my car is a bit on the "out there side", I'm just going to stick with GIAC programming and I know it'll get better and better with time for my car. It just takes some patience is all...

I'm not knocking the upsolute stuff at all. I used to have it and when I had a basic set up on stock turbos, an exhaust and air filter, that was one great bang for the buck. It's just a lot more complicated to tune for all of that "extra" stuff.... You don't just take the base stock map and modify some parameters here and there when you have as many non-stock components as I do It's complicated.
