Good tests.

The only downfall is adjusting the timing with the dizzy. When moving the dizzy, you are changing the timing throughout the entire map which does not make it a fair test.

Running the larger lift cam lowers the static comp allowing you to use more timing in certain area's. When raising/lowering timing on the dizzy, lets say 5*, you may kill low end, while improving top end and vise versa. I am confident there is more to be had with the 20V's with some timing in certain areas.

Play with your gears and see what you find. I am sure you can pull more out of her.

So the 6262 has the new turbine wheel. but it is going to be a couple weeks before i get it on. At least. Gotta get some cash up front to pay for it.

My 3076r will be up for sale if I can get the 6262 to fit lol. Hopefully it all clears.

Ok, so let's see what you guys come up with as far as guesses on power with the new turbo. Any takers? If this thing fits then I'm going to dyno again and see what it will do.

So... I'm gonna put my guess out there... 10psi I am betting 350whp. and 20psi 480whp.

I'd like to be let down with better numbers, but I'm leaving some room out there for improvements to come with tuning.

You can get the journal bearing 6262 and you wouldn't notice any lag and it's a lot cheaper than the bb. 500hp shouldn't be a problem.

500 all day with the 6262. Thing is with a bigger frame turbo you can't be scared to give it boost. A 6262 at 10 psi is a tease for that turbo. 20+ psi is where they start to sing!

I just hope it fits on the manifold. the 1.06 housing I have on now needed a spacer to fit. Now, I have about .5" to the right of the compressor inlet before the turbo would touch the radiator hose. And about .5" from the head before it would rub on the head. and 1" from the radiator.

I think the dimensions of the turbo are nearly identical to the GT30r, but the S compressor housing is a bit bigger and that's the thing I worry about. Could always get the E cover if I had to. But I don't wanna.

I didn't want to start shit for obvious reasons, but was thinking just this. I was thinking not just the lift, but also the fast ramping on the intake of that high lift would change things. If he had tunable timing you prob could get pretty aggressive just after the cam switch with the 20v's

Still makes me feel good the 16ve's performed so well as I have a set and want midrange. But, even with the dyno's posted I think with a good tune on both cams with gears and ecu the 20v's would perform better than the 16ve's everywhere.

So coheed are you going to get this one with the .84 t4 divided housing? All you would have to change would be the flange on your manifold right?

i think you will be higher than that at 20 psi. With the newly designed 6262? I make 465whp on my boosted sr20de with a sc61 at 19psi, the old school garret core.

I predict 500whp-520whp at 20 psi on that 6262. That is such a sick turbo! Good luck! You guys keep going bigger, but after this year Im going smaller, to a billet 5857 or possibly something even smaller.

I would go T4 TS but it is out of the budget this year. It would be a lot more work getting a T4 to fit.

the .82 is bolt on and should clear everything hopefully. I hear tons of good things about the 6262, and hopefully this baby delivers. I would also like to see 500whp by 20psi, but 8.5:1 compression may just hinder me slightly in that.

I figure, a 9.5:1 would be better suited for it, but at least the 8.5:1 will give me some head-room with boost. 15psi on pump will hopefully deliver a very nice powerband with a lot of kick.

I am interested to see how the different turbine wheel will affect spool. Hopefully spool like a GT35r or possibly better. Of course I don't really want more than 500whp, but I want to me able to nail the target without messing around with the setup that may otherwise compromise in simplicity. I'm not looking to make insane power. Just hit my goal, and have a fun setup that isn't too laggy. The 6262 specs out as only marginally larger than the 60-1. I suspect the larger turbine wheel will be what dominates this turbo over the GT35r.

A lot of friends are big garrett fans, and all want me to buy a GT35r. But I am sold on the precision unit. And I don't feel like paying $2000+ for a GTX turbo that doesn't really perform.

I have seen a GTX30r make 600whp, and a GTX35r make 800whp. But the 6262 has more personality... like Charley Sheen. Bi-WINNING!

damn it I said peer pressure. t4 twin scroll. lol

what really needs to be changed to go to t4 twin that will cost? you should at least look into measurements, as the turbo cost is the same, and you already have the twin scroll set up. cost should be very small if things fit well. I think its work exploring the option.

Peer pressure!
