Ouch The 280 hp looked like 200 first time I viewed the dyno, 200+ hp is great nonetheless.

 

hahaha me too!!

 

yes a chart!

 

UK 99 octane is roughly 93-94 octane here in the states right?

Looks like it only spooled about 500rpm slower than the stock turbo? That's even better than I thought!

 

Ah, good catch.
370 on pump with stock cams is pretty strong.

A 3076 in a good 2 liter like the 4B11 or the 4G63 will shine brightest on race gas with around 28-30psi.

 

Basically 26 psi tapering to 23 psi, reduce the taper to 1 psi or less and that will be a solid 500 crank HP the way it looks.

The 500 rpm lower spool looks promising as well since I gained 200-300 rpm spool on the stock turbo just with MIVEC adjustments, that would put it only slightly slower spool to 20 psi with more HP on tap. Looks like a great area under the curve and very streetable turbo!

Now if someone would just sell me a good stock location Tubular Exhaust Manifold I could get this baby installed as well! Every option I've checked into is out of stock for a few more weeks or comes with an unknown ETA.

I just got back from Watkins Glen and after leaning out my original tune about .3-.5 AFR's I was still rich enough for zero knock on the road course for 20-30 min sessions and the car is running perfect with much less soot on the bumper. Do you think it's wise to do the fuel pump and injector install before the turbo and get it back to where it is before bolting on the GT30 turbo? Seems like it may be wise to reduce the number of variables even if I have to tweak the tune after due to being in higher load cells.

 

Fix it for ya

 

Your gonna have to re tune it anyway, load does not go up as much as you would think. I'm fairly sure the X prefers the map sensor once you are in open loop as far as load calc goes. EcuTek has a map sensor scale table that can be adjusted, not sure about ecuflash.

 

I was thinking it would likely be at similar 240% loads at low RPM's then climb to the 260% load area and not fall off as much past 6000 rpm where the stock turbo would drop to the 220% area. As a start my timing maps are about 1 degree less advanced as load increases, we'll see how it does with ~11.3 AFR's that I have set right now and tweak it once it gets on the dyno. Hopefully I'll be able to dial in the Deatschworks 800 cc injectors pretty quickly and just tweak the rest of the maps. I didn't know there was a Map Sensor Scale table in EcuTek that can be adjusted, maybe someone more familiar can chime in on that.

 

The Deatschworks 800 cc injectors work great !! Idle is great and they are running around 70% @ 480hp with a 255 pump . Having all correct latency value's supplied is a luxury .

You are correct about the load not falling off as much. 11.3 should be fine egt wise. I never had any issues with egt till I went about 11.8 - 12.0. X does a way better job of getting heat out of the cylinder than the VIII's and IX's so you should be just fine up to about 11.5 for track use, but, of course your mileage may very

I have not needed to touch the scale table, but it is there and the X uses both map and maf. I have seen first hand that it prefers map (or in reality it could be whatever the higher reading is between map and maf) when I was tuning an X that had meth trigger tapped off the map sensor signal wire. Ecu was never seeing more than 1 bar boost pressure on the map sensor and was clipping load at about 220%. As soon as we fixed the map sensor signal wire issue, load jumped up to 250 +

Also the latency's provided with the deatsch works are a good starting point but don't consider them to be 100% correct for your setup.

 

Is it possible to get 500WHP with the GT3076R Tubro if I get a Tubular Manifield, Turboback Exhaust, Intake, Bigger Intercooler with hardpipes, Bigger Cams, 800 cc Injectors, Fuel Rail Kit, and a Tune? I plan on getting stronger head studs and gaskets.

 

I figured they would be the safe path to go with and happy to hear your findings.

I was hammering my car at the Watkins Glen road course Monday and Tuesday, the car ran flawlessly at 25 psi with the usual taper past 5500 RPM's and ~11.3-11.5 AFR's all day long. My knocklite never flickered any knock and the car never skipped a beat revving to 7500 in 4th quite often (7800 limiter). I kept the fuel at half tank or higher to avoid the fuel starvation in the one off camber left hand turn there. I think 11.5 is a good balance to shoot for on the new turbo, certainly my rear bumper agrees with the leaner setting, although a bunch of people came up to me asking why my car was belching fireballs still.

 

OH SWEET QUESTION!!!!!!!

Dude read the thread....and don't play this speculation crap game. There are barely any cars with this turbo currently and only 1 dyno graph to speak of.

 

FYI, I think Full-Race had a few manfolds in stock. Perhaps they were sold already.

As for A/F, I'd probably just keep it at 11.3 to keep the EGTs in check. I do not think the extra power gain or mileage of going to 11.5 is worth it relative to reliability. If your car were just a street car with a couple WOT a day, then I'd say 11.5 would be perfectly fine. But since you're doing extended track sessions, I'd just keep it richer

As for the timing, I'd be interested to see how the maps look relative to stock. I would think that you should be able to run significantly more timing relative to stock due to the reduced back pressure from the bigger turbine housing.
