Back to 11:1 CR on e85 and hitting dyno tomorrow
I recently made 789AWHP on my EVO with a 6262 with the WG dump being thrown back into the exhaust... It was causing a lot of back pressure issues doing this... I have since changed it to dump to the atmosphere and although i haven't been back on the rollers i can tell the car is up at least 15hp or so! The boost curve totally changed for the better, the car hits SO much harder and i had to add fuel to the tune and this means more HP
Id say its a little over 800WHP but its maxed out and i mean MAXED out lol. I have ran it as high as 52psi dropping back to 49psi giving it all it has but it didnt make anymore HP over 46psi just more TQ and back pressure causes by my return dump had some to do with that for sure.
Now i do know the Honda engines suck up more turbo due to obvious reasons with flow etc. But the 62mm wheel will make 800WHP on these cars especially with there lower drive train loss compared to say an AWD EVO drive train. The 6265 might be an easier turbo combination to hit over 800WHP with on the S but i think the 6262 will do it if pushed hard enough and produce quicker spool, broader curve and more TQ while doing so. JMO and we will see what we can do when Chad is ready to give it all it has!!
BTW siadam you are correct the boost did drop up top on that pull. It hit a peak of about 32-33psi in the mid range and fell to 29.6psi up top there. But at this point Chad was happy and didn't want to push it any harder. I'm sure i can get that boost back with adjusting the boost through the AEM up in the upper RPM range

How long do you think a bone stock motor would last under such rigors if all I did was drive it during nice weekends. But when I drive it I will be really getting in it? sorry to thread jack, congrats on some insane numbers, Id just like to know if this is a direction I should head off in.

This isn't a critique, just an observation, but the graph looks like boost was starting to fall up off top. Was this due to the gate, or the turbo running out of steam?
I wonder if the 6262 has much more in it?
I would have thought it would have run up into the ~35lb range.

Yea, but thats not a fair comparison.
6262 on a Honda motor. I have never seen it.

Second car. e85. Stock sleeves. Lot o' boost.
