ok...see you soon

 

Great work guys!

The 9 psi run does seem a bit odd, but the 15 psi run at 580 or so seems on par with GTM's results. Those HR's breath well on the top end, no question. (thanks for the link)

 

Must the engine be removed to install TT? This is the third twin turbo built I've seen and the enigne is always removed from the chassis..

 

so what is supposed to the benefit of tuning with osiris over piggybacks or standalones?

 

Yes, we just installed another HR TT kit with the engine in the car.

We only drop the engine when doing a complete build.

OEM Integration - no wiring/splicing and possibility of bad connections
Less expensive - vs a standalone
Better control - its not using MAF offset, or other methods of the sort.
No idle issues, hot/cold start issues - as seen with UTECs

and the list goes on

 

so how is timing control compared to the alternatives?

 

Nice congrats.

11-12psi sounds much better, thats like 23-24per psi of boost....that sounds do-able with the HR head flow numbers.

 

I just did my GTM kit on my back using jack stands.

 

Like OEM, you are just changing the values - you have full control over fuel and timing.

Another HR at 9psi different turbos but close to 500rwhp.

 

It just makes it easy. Sam at GTM has a kit that can be installed with engine in the car. We are going to install one of there kits real soon.

 

The amazing thing about this build was the Osiris tuning software. The car feels like factory with two turbo’s. I asked myself is this what a GTR feels like? The drivability is just simply wonderful.

It’s nice to have 500 rwhp, but if you can’t drive it to the store without having issues. It’s not worth it to me.

 

^You've had the chance to drive my car which was not tuned using Osiris and the one you guys just built, although you drove mine with the boost of how would you compare the the drivability between the two?

 

9-10psi is easy for 500whp on a DynoJet. Looks like this type of Dyno reads fairly close to a DJ. I havent ran an HR past 11-12psi, and when we did, it made 540whp on a DynoJet, and just over 500whp on our DynoDynamics. That said, the 580 number looks within the ballpark at 14-15psi boost pressure.

Good job guys!

 

I drove your car about a half mile, so I really can't say. One thing I did notice is you car air fuel is rich.

 

Good job, Bobby...

S&R is turning out some nice work...

 

+1 From what I've seen, and having dyno'd on both a DJ and this dyno, they're VERY close IMO. Good job Bobby, git'n her dun

 

Please explain further about the air fuel being rich.
Also, Taylor or Diego drove it a bit more when they test drove it, would be nice to hear their opinion on it, 10x.
