I know its not a Z/G, but I though you guys might enjoy this!

We just wrapped up a GT-R build equipped with our GT800-R Turbo upgrades. After dwelling over a fuel problem we encountered during preliminary runs, we finally completed the necessary fuel system to support 700+whp. To make more than say 650 or so, an increase in fuel delivery is essential.

With our fuel system bolted on (details coming in a different thread), it was back to the dyno.

The results WITH 3"AAM HF CATS (3rd Gear pull):

702AWHP / 618AWTQ SAE @ 21 psi w/ 100 octane.
708AWHP / 623AWTQ Uncorrected " "

The only limiting factor was the boost cut associated with the OE sensor which kicks in a little over 21psi or so. Once a viable option is available, hopefully HKS for ems, I'm sure we can squeeze more out with boost. Regardless the COBB performed flawlessly coupled with the OE pressure sensor up to around 21~22psi.

Also, I want to give a big shout out and thanks to Jorge for his patience and understanding while we finished up his beast! It'll be back in your hands soon!

nice....how big are the turbos?

tom

 

good lord...

awesome stuff AAM!


Zquicksilver

 

Very nice- thanks for sharing

 

^^ Thanks guys!

 

Wowsers.......

 

 

i liek the dynosheet, like the work.... hope its all as good as it looks!...i like the custom work

 

Congrats guys. Can you please post the compressor chart for those turbos or specify what might be an equivalent sized Garrett? It bugs me that 4" cats robbed me of 60-100 whp and you guys made 700 with 3" ones! Nice, but what gives? I suspect a much bigger turbo than what I'm running. How many cell cats by the way? Thanks!

EDIT: I think the Haltech for the R35 is available if you're looking for a standalone EMS!

 

Pics of the actual car?

Work looks awesome, and I'm sure the car goes like hell!

 

Nice build AAM, also interesting in HFC info as well.

 

Thanks for comments everyone. I'll post pictures of the full car once we finish with all the carbon exterior components in the next day or so.

Ahh yes - cats around here have been a big thing lately for the same reason.

First we made 500awhp with cats, then 550awhp. And then I said, well that's probably about it with cats. But the car that made 550 decided to upgrade turbos and keep the cats - and then we cracked 650awp on 93 octane with cats. LOL, and I really didn't think we could make any more until we hit the 700 mark. I can tell you for sure, I think this is about the limit for our HFCs. Now we'll just be missing significant gains if we don't switch to catless dowpipes from here on out power wise.

This particular car had another brand of 3" cat and midpipe on it and we could barely crack 600@19psi. With a switch to our 3" HFC cats and our 3.5" midpipe we picked up 60whp

After dealing with various brands over the past few years with mixed results, I finally found someone to make me custom cat cores with a super low 200cell count as well as a custom body. Just because a company claims its cats are metallic and high quality with cell count xxx doesn't mean they are. I've been let down more times than I can count testing "High Flow Cats" on turbo cars.

With our new low cell count metallic cats, we have seen no CELs and HUGE gains on turbo cars over previous cats.

As far as turbos go, you'd be surprised. Believe me - a lot of this power is associated with how well this motor breathes. We kept the stock turbine and compressor housings - so we were working with limited room. We machined and installed new CHRAs in the stock housings for a bolt-on application. And I really have been pleasantly surprised with the results.

We have a few others here getting bigger comp wheels and covers, so I think with more boost and the bigger covers we'll be deep into the 700s.

Right now, if you read up on the Haltech for the GT-R - there are many issues that still need to be worked out before it is a completely viable option for aftermarket turbos. Plus - the COBB AP allows open ECU access. It has its restrictions - but there is nothing better than the OE ECU!

 

^Huge ups for that.

 

Wow.Very cool! It sounds like you guys have turned things around there at AAM! I remember hearing some "stories" a year or two ago but since that time,it has been nothing but good news coming from your shop. Major props!!!! And also that billet tranny pan is incredible! Nice job guys!

 

Very nice Clint.....800whp and I will take another look at that car

 

Thanks Tim. Yeah that transmission pan and cooler was a major undertaking. Probably the most machine intensive part we've made thus far. It looks good and it works too!


You might be taking a look sooner than later

 

..........................

 

ya someone needs to test when the rods come flying thru the block. If Nissan wanted 20k$ for a tranny replacement, wonder how much a new block would cost

 

 

yeah, a good ems, catless exhaust, and a few more pounds of boost should do it.
