As many GT-R owners are finding out, the 600-700 whp power level is simply not satisfying the itch for power. 900-1000 whp has become the new benchmark for 'fast' street driven GT-R's. It is for this reason that Doug brought his GT-R back to us after only having his Alpha 9 setup on his car for a few months. His stock block corn-fed 655 whp GT-R was too tame and comfortable to be considered a street monster. After AMS released information on their Alpha 10 setup, Doug saw the potential of these cars. It was decided that this was the way he wanted to go with his GT-R. Since E85 is abundant in his area, it will be the primary fuel of choice. We prepared a full array of supporting parts, including one of our in house assembled long blocks, and Dodson transmission upgrades. Fast forward a couple of months, we are now almost ready to throw this beast on the dyno for tuning. The last AMS Alpha 10 setup we prepared made over 1000whp. Pictures of the progress are listed below, and we should be ready to fire it up very shortly. After completion, the owner insists we take it to the drag strip for some passes. Stay tuned for updates!

Good looking kit.

Looking forward to the drag numbers!

Are the ams10 kits wet sleeved blocks?

We build our own motors in house here, so it is not an AMS block. We have a few different motor packages to choose from. Our standard FP1 does not use any liners or sleeves. Our FP1-R uses an iron liner, but it is not a wet sleeve.

In regards to our engine program we use a wet sleeve on our 4.0 builds but we have a special engine reinforcement service we use to keep the block together under high HP.

Nice build to all involved..

Will 2 044's be enough pump for this setup on E85?

Based on the DC's and pressure I observed with the last Alpha10 I tuned running petrol at 1000whp+...yes we should have sufficient fuel for 900whp+ on E85. We also have an additional piece we can add should more fuel be required.

With regards to our engine program, we have two different fundamental engine designs. One uses the OEM liner, and one uses a nodular iron cylinder liner. You can have a look here for pics and details: http://www.forgedperformance.com/store/product.php?productid=17395&cat=512&page=1

Looking good Sharif!

I noticed AMS and other shops use non T-bolt clamps..I don't know if it me being paranoid.. but all my clamps are T-bolts and have almost no chance of ever moving or coming off..

I have seen those clamps get loose over time and cause a head in trying to find boost leak..

Oftentimes, there is insufficient space, to actually properly place a T-Bolt clamp. We've tried just about every type of clamp out there and a quality worm clamp works best for us. For race applications, we'll install bosses and safety wire to make sure the pipes and couplers don't go anywhere.

In many cases, the reason that a silicon coupler blows off is not due to insufficient clamping force or very high boost levels, rather it's from misalignment, angle, or unnatural tension on the pipe...ie not accounting for engine and chassis movement under hard acceleration.

Sharif,

When will you guys get to that full custom Diamond Black R35 with Alpha 10??

Ah,the very very special car. It's under wraps for the moment...it underwent a complete teardown for the most amazing custom paint job I've ever witnessed. It's ready to go back together as soon as Jason wraps up this Alpha 10. We have quite a few builds in progress that we haven't posted about just yet.

I'm really interested to see what you can make on E85 until the bosch pumps max out. 900whp+ seems a little optimistic. When do you think it will be on the dyno?

Good luck and keep us updated!

900 will be fine on 2 bosch pumps with large injectors. No problem there.

I believe it will be close but it's not overly optimistic. On a low reading Dyno Dynamics, we saw over 1000whp on petrol with rock solid fuel pressure all the way to redline with a slightly modified AMS Bosche Twin Pump setup. All dynos will read a little differently, so I always take the numbers with a grain of salt...900whp on one dyno, might be 1000whp on another. As always, we'll share our findings with the community as the limits are achieved. Oftentimes, it takes just another 10% extra fuel flow to acheive a power goal, and there are other ways to do that without installing more pumps and lines. We are trying to keep everything as OEM as possible, with all internal pumps, safe machine assembled and testing fuel lines and so on.

This is a very extensive build, where no part of the car is untouched, so bear with us as we wrap this baby up. Thanks!

It will be close. I'm estimating about 850whp on a dynojet with my Alpha 10 setup w/ E85. The Bosche pumps are little better than the Aeromotives that I'm using, so you might just hit your mark (probably not on your lower reading dyno though). Not many high power E85 GT-Rs out there yet, so not much data to go on.

Sharif / Ryan, What happened do his Alpha 9 turbos?

Mike, On E85 you will EASILY MAKE 1000whp on a dynojet.. Im willing to bet any money..

I made with my stock manifold turbos on E85 842whp on a mustang dyno.. add another 10% for dynojet and bigger turbos? easy 1000..
