I don't have a whole lot of time as we are still tuning and about to close up for the weekend but we have our SR750 package on the dyno in the form of Franks white GT_R

Current HP is at 665 whp and 500 ft lbs of torque by 4000 rpm .......... on pump gas. At the heart of this package are our widely recognized bolt on turbo upgrades.

I will get everyone more data on monday. We still have to take off the stock IC piping and toss on our 3" piping with HKS valves.

This package will be available to the public in just a few short weeks

Eric

Looking good!

very nice

Awesome. do you guys think it will hit 700whp with all said and done

Bad ass Sir!


Looking forward to Monday ;-)

WOW.....O_O

Yes it should make at least 700..probably a bit more but what impressed me even more was the torque. Over 500 ft lbs at 4000rpms. That was with the stock intercooler pipes. AMS is installing the 3 inch pipes, a few other goodies and doing a re-tune next week. NO shifting issues so far.

Congrats car has every bit of 700+ in it TIM

Hey Tim

Got to get all we can out of her before it heads down to the TX2K10 GT-R Nationals and the Texas Mile. There is going to be some stiff competition in both those events thats for sure.

Also can't wait to see what the car makes after the last minute tweaks and re-tune next week but what really is getting me excited is the thought of driving it again. It seems like a lifetime has gone by since I drove the car back in Nov in Vegas at SEMA.

Know what your takling about on driving it!! but will be worth the wait Good things come to those who wait !! !

do you have the list of all the mods so far?? sounds very interesting!!

No problem....

Power mods are as follows:

AMS Turbo Upgrade
AMS Full Exhaust (Downpipes, midpipes, catback)
AMS Upgraded Fuel System
AMS front mount intercooler (3 inch piping will go in on monday)
Cobb AP

Thats it!

In all honesty, its not a whole heck of alot of modifications compared to the other projects going on right now, BUT the numbers are showing that this setup will be quite POTENT!

Cant wait to hit the tracks!!

Presumably an intake as well, if your MAF is standard size you can dramatically improve the mapping with a bigger MAF housing.

I'm not sure what is on there right now as I'm not actually there to see it but I believe the MAF's are still stock.....

and if thats the case then +1 to what your saying.

Sorry I don't speak so much English...and the ShortMessageSystem language for me...it's so good, please what is mean MAF ???

Tried a large MAF housing intake at Horsepower logic and it was a nightmare. Jack could not get the thing running right. Probably because of stock turbos and too big a pipe. Is there new mapping for larger MAF that fixes this now Thistle?

They are talking about the Mass Airflow Sensor

Hey Bret....I have since been working with a few larger MAF housings and the latest injector scaling parameters in the AP software is much better!....

-Jack

To avoid taking this thread off topic, I've posted some info about MAF/injector scaling in the Engine forum.

Is it me or WTF,,,665 whp and 500 ft lbs of torque by 4000 rpm !!!,,has any other tuning package matched this number...for give the excitement here I drive a 130 hp civic

Not cause its my car, but I agree...... it is kind of a big deal LOL

This car seems to be building a tremendous amount of power VERY quickly!

so this is 50 more Hp from the last time you had the car at the track? any reason why you did not go for over 700whp? seems like alot of down time for 50 hp net ..


will you get a c16 or high octane tune?

would like to see how hard these turbos are working with a boost and dyno chart


last question , mustang or dynojet?

My car was used for prototyping on some of the components for the 750 package along with larger builds AMS is doing right now (fuel, piping, etc.) .... The car has been down since Sema (Nov.) So all in all, for about three months she has laid dormant. We also sent the transmission out for a few upgrades as well.

We will be using a higher octane, 109 I believe.... I think C16 is a little excessive for this setup. It might pick up a little more power from the C16 but nothing dramatic.

When Eric posted on here they were still tuning. I got a text from him later that night.... "670whp and 595ftlbs of tq. conservative tune. 19psi. factory BOV's and piping are hindering...were done till monday. Hit 190mph on the dyno LOL"

700whp + is very doable on this setup and I think on monday Eric will show it.

And to be honest, Id rather be conservative on pump gas..... I mean think about it, its an everyday tune making very solid numbers and able to go faster down the 1/4 mile then we already have.

The real important test is what the car does @ the Texas Mile and TX2k10 in the next couple weeks.........

dyno numbers are great, but track times are what count.

That makes sense..would be nice to have them do a 109 octane tune for a possible 9sec slip ;)

VEGASGTR. 9's and a attempt to hit 200mph in the Mile are defiantly on the to do list when we hit TX with the car in a couple of weeks. Hopefully the weather/DA/track conditions etc. all fall into place. If not the car will be coming home shortly after that and we will have to hit up some of the tracks back in the NE where the DA is usually very good once this damm snow and cold weather clears up.

: )

Thanks everyone, we hope to continue tuning later on today.

We started playing around on race gas and we were hitting 685whp and 700ft lbs of torque. HP was dropping off though as the factory BOV's are now not holding anymore. We are going to take this opportunity to put on the larger 3" piping and some HKS Valves and see what happens. So far we are pretty impressed.

The car has the following:

AMS upgraded turbo's
AMS Front mount intercooler
AMS Catless Downpipes
AMS resonated mippipe
AMS race exhaust
950cc injectors
AMS fuel System upgrade
AMS intake pipes with larger MAF housing
Cobb AP tuner
AMS Custom tuning


Later today we will add our 3" IC piping and HKS BOV's to try and curb the boost problem.

Eric

Upon looking at our logs and what not we have noticed that our already increased MAF housing it being overworked. We are in the process now of making even larger MAF housings / intake pipes and the 3" IC piping upgrade. This car is moving some SERIOUS air!!

I doubt we will have time to get the car back on the dyno today but I will keep you posted.

Eric

so no trans upgrade?

Yes it has:

All Willal upgrade minus clutch discs
PPG 1st gear upgrade

Eric

Very excited for you Frank. Its gonna be fast!!!

Thanks Hing

The real test will be on the track as you know.

Good news is it will be heading down to Texas soon where the weather is a little warmer than it is up here in the frozen tundra LOL

: )

Good job AMS

Here is a preliminary dyno chart where I left off on Friday. The pump gas numbers are on there, as well as one of the first pulls I have made on MS109. The car shows alot of promise for the race gas mapping. I can't wait to get it back on the dyno with a few 'tweaks' and see what it really can do!

With the load difference on the street we expect peak torque on this setup to be between 4200-4400 RPM.

As you can see the boost falls off a lot due to boost control and the BOV's

Eric

Woah, the VR38 is like a Cummings 6L V8 Diesel, and I dont think its even putting out that amount of torque,,,lolzz,,

IM LOVING THOSE TQ NUMBERS!!!

I cant wait to see the end results!

Congrats on the progress and results so far!! Very impressive Looking forward to meeting you guys and seeing the car in Texas.

Same here Jason.

Looking forward to meeting a lot of the members on here that I didn't get to meet at SEMA.

Let's hope we get some nice weather down there for the event. It should be a lot of fun!

Thanks Eugene

You guys are also doing a bang up job on the GT-R.

WOW very impressive, I'm sorry if i missed it but what are the specs on this kit? and price?

We have part listings above but price is not yet released. It will be competitive with the other packages on the market. BTW AWESOME sig pic!


On a side note we got the intakes and IC piping done but Chris had to go and screw up our time table and have a baby.....big jerk lol

In all seriousness though Chris and his wife are at the hospital right now as they await the birth of their new baby boy. Lets wish them all luck and I will keep you posted on the SR750 package and its updates.

Eric

Congrats and good luck Chris!

Congrats to Chris, hope the fam is doing well, and AMS you guys impress me more and more with each build

lookin fwd to the end result guys! awesome build!

Congrats Chris!!!!


Eric keep us posted when the little guy comes out into the world!!!

+1 congrats Chris

Congrats....Chris

Are you controlling boost via a HKS EVC, or through the Cobb's rpm-based WGDC developed by Thistle?

Is there a certain level of boost/power output where the Cobb rpm-based WGDC simply won't cut it (and an EVC type of device becomes mandatory to ensure stable, consistent and predictable boost levels)?

The stock turbo boost pressure sensors clip at about 25 PSI. You can go beyond that by using open loop control, switching to mass airflow based control (not done but easy to switch) or changing the boost pressure sensors (not done yet but should not be too difficult). We have run a car with stock turbos on 94 octane with induction/exhaust/800cc to 700lbft (Dyno Dynamics flywheel) at 25 PSI at 3150 RPM. There were no problems with fuel cut or control, even though I think that is too much boost for this spec/octane.

So you're saying that anything beyond 1.7 bar requires one of the three steps you outline above? How difficult would it be to change the Boost Pressure Sensors? Is it known which aftermarket sensors will 100% properly do the job on a R35?

In my case, my car is just about finished having its SPE750 turbos installed. When running the HKS GT570 kit with the OEM turbos, the boost had been controlled with a HKS EVC. Is there any downside to running an EVC with my upcoming modified turbos, or will your rpm-based WGDC provide more stable, predictable, consistent, and much-less-likely-to-spike boost output than the EVC?
