Sorry I'm typing this stuff on my phone and is a pita I had actually just tried to edit that info in and accidentally pressed cancel while trying to scroll. Anyway I'm not overly worried about the spool of the DR750s on the 3.5L that's the reason I picked this setup to begin with. I believe it will net me the widest power band with the least lag I can get, which is the she goal for my car.
I don't think I have convayed that very well up till this point, the purpose of the thread was to ask if this was the best set up for that or if there were better setups for this purpose.
The open dumps will be on long before the engine/turbo combo goes in they are mainly for the 9bs I'm running now, just see no point in removing them later when they aren't going to hurt anything and will still have a cool factor when I'm not pushing the 30 psi.
3.0L, MHI 19Ts, AEM EMS, and every bolt on you can think of. 94 oct./Meth.
RMRwe have no idea what we're doing.
i don't understand why people here believe the only way to have little turbo lag is small turbo with bigger engine. we are so damn behind. other platform run higher compression ratio to get rid of this issue. people run as high as 11:1 ratio to get good power band. not only that they make more power per psi because of that. if you can get E85 or pretty good pump with big methanol i would run 10:1 or higher to get rid of this issue . i bought my stroker with 9:1 ratio and when i look at other platforms, i sometimes wished i went with 10:1 ratio. AMS up their GTR's compression ratio from factory to get better tq and power band when they build the engines and the factory gtr already has 9.5:1 ratio.
You make a very good point Gump that i guess I've never been very clear on when using the 3.0 v 3.5 comparison. Net HP will be the same, you're just gonna get it sooner. and maybe lose is on the back end quicker, kind of like big turbo setups do with our stock truck cam.
Silverstone Metallic 94 R2 FD - 2015 F250 Lariat Ultimate CCSB 6.7PSD
Sold: Black 99 VR4 and two Pearl White 93 VR4's.
keep in mind... he's in Canada. His "good gas" is probably more like 91.5 in terms of the way the U.S. regulates octane ratings. At leat thats what the local gas stations here (who's gas comes out of Canada, we literally live right on the border) are now required to list their "Super" gas as. (they used to advertise it as 93 as it was sold across the border... but it cost a few people their engines myself included... threats of lawsuits ensued) Also it sounds like he's at a pretty good elevation, and has a LOT of tight lowspeed turns. He's finding 9b's laggy based on where he is and the conditions he drives in. 9B's. When was the last time you heard or thought to yourself "man... I wish these stock turbos spooled faster..." Probably never. But that is the reason he's looking for faster spool. People seem to keep forgetting this. Telling him a dr-750 on a 3L will spool plenty fast enough, or focusing too heavily on the HP number isn't really going to help him.
To me, a summary of what he's looking for:
1) Stupid fast spool (to most of us anyways... I'm going to assume his engine/turbos are in good shape with no boost leaks and it truly is driving and environment where he lives as he stated early in the thread that are the cause of this need)
2) More power, 700 "goal" (because... well... who doesn't want more...)
3) Wide power band, starting very very low in the RPM range (see #1)
4) 1-3 accomplished on crappy Canadien gas (there IS a reason that Eric brought a can of crappy Canadien gas with him when he had Ray tune it the first time) and meth
I really do like everyone on this forum... there is a wealth of knowledge on this and the other site, and I've never seen a more helpful community but sometimes it seems like people lose track of the original intent of the thread and get to focused on 1 or 2 items or sentences or skim over important details like quality of available gas.
hmmm... Thats info I didn't know... and checking the rating systems, petro canada "ultra 94" for is 94 (R+M/2). So that would support what you're saying.
I do know however that the gas they were trucking across the border and selling as 93 here actually only tested at 91-ish (R+M/2). Wouldn't be the first time someone's done something shady with the gas here though so maybe I shouldn't lay blame on all Canadien gas.
I recind my comment about doing it on crappy gas until the OP gives us more info on whats available to him.
sometime i wish JasonY was closer to me :-D . Anyways, I have seen many people talking about how much they can get out of a set up. It always involves Meth.
I hate Meth for a reason (Jason stated)
Also, Jason has been through many tubors on his own. I would take his words on the pump gas. I too did many researches about turbos systems and so I never seen any TD04 which broke 600 AWHP with Pure Pump gas.
