Damn, those are some great numbers. My 25g is going to be installed today. I can't wait to see how it feels. I will need to break it in though before I hold some boost. The 91 octane numbers are awesome. Looks like I might be able to hit my 400whp goal at 20psi.
You should hit it, are you going to do e85?

I think if he was.too get on full e85, hed make 550+ all day long, but he mentioned something about the cobalts.not.being.able.too go.full e85. Me on the.other.hand, Ive got.enough fuel.for me and payam too blow our ****.up lol. I know we dont.own evos, but nonetheless these 25g turbos are going.too do work
great numbers. I cant wait.till I throw my 25g fp unit it. very excited.
you scaled.for.4bars or.are.you still on the 3bars? stock block? and what.hotside.are.you using and turbine.wheel? curious. again though, great numbers man

ok. got a tasty build 
the td06sl2r green wheel seems too be doing a fine job keeping up with the compressor wheels capabilitie. I see how well the cams aid in your setuo, and how that little.turbine wheel is doing fine without the clipping too. I mentiined too Vlll driver about the switching.of turbine wheels with the larger td06h4r wheel and its not hard at all. any turbo shop can replace the shaft etc..but the onky thing that needs too be addressed would be the turbine housing. It would need too be bored obviously for the larger wheel. other than that itd be good too go. Could be done too help support a bit more airflow out these 25g wheels if your looking for that extra bit of power too squeeze outta these things. I can already see how much of a difference the billet wheel does vs the cast 25g wheel. very impressive.
what exactly do you got planned for your car? any drag times? where in so cal you from?

Maybe! There is a new custom 5th injector kit I'm looking at making. I need to ask my tuner what he needs me to do but I should be able to run full e85 without losing fuel up top. For now I usually run 91 for DD, and race/kill mode is 100 octane or e47 blend.
Man, you have enough flow for 2 25g's LOL. But yea I have coolant leak, my line cracked. I don't have any coolant going thru the turbo right now. I need to order new lines. I'm having some cpompressor surge, need to firgure out why it's happening. I'm not getting any BOV release but all my lines are correct... Idk. This custom set up took 20 hours to install bro. From 11 yesterday till 8 am today. I'm beat

have a questiin for you 25g users. How do you guys feel about your kinugawa drilled anti surge compressor covers? Would you guys say that this cover is effective and working like a anti surge cover's supposed too? Im contemplating ordering one too try out and experiment with as there $100+s&h. I have a slotted fap cover from FP, but still willing too try and experiment with Kinugawa's drilled a/s covers and see if I can notice any difference between the two and see maybe if the butt dyno notices any change in performance and spool.
any info and personal preferences, experiences, and opinions are welcome. Thanks

I bought one of these turbos from klever(great seller btw!!!!) I finally got around to installing the lr 2.4 motor and this kinugawa turbo. mine is a cast 25g and I also live in high elevation (5600 Ft) here is a vd I just did of a very conservative 23psi tune on pump (91 octane) afr's look a little rich but that is because my formula is wrong in evoscan. mtx-l support on evoscan sucks!!!!
actual afr's are lowest point 10.9 under full boost

Just wanted to share some results of some things i'm trying out, this was a bit of my tuning session tonight and last week, my car had put down 510-517 before at 30 psi, however it was a very peaky curve with power falling off at the top end, at the time it had GSC S2 cams and PTE 1200 injectors with the stock 25G cast wheel, now i just installed GSC S3 cams, FIC 2150cc injectors ,the 25G billet wheel and a Grimmspeed 3port solenoid, the tune right now is pretty conservative and timing still has some ways to go, also a bit rich on the top end to keep things cool so definitely there's more power there once i finish tuning it, by the looks of it i can get away with 32 psi on pump with a decent safety margin, right now it's at 29 psi on pump, the two graphs are two weeks apart, only difference being the billet wheel and 3port, i did notice a considerably drop in spool, about 900rpm just from switching cams, however the power keeps on going on the top end, i do miss the brutish power delivery (torque due to quicker spool) of the S2s, i think i'll be trying out the new R2s soon, they should help my 2.4LR get that torque back and not die out on the top end, the tune is on Tephra V7 and SD.I bought one of these turbos from klever(great seller btw!!!!)
