did the kit arrive yet? i expect it installed no later than sunday. no excuses!!!

 

not here yet....should be tomorrow though.

 

This kit should be a monster... I cant wait! Goin on a built block right?

Vas, I wish ur block was built... From the looks of the turbo n power it put out its still yawning at those levels... 15psi on a built block id love to see the kinda numbers it puts out...

Maybe BP could chime in but how much power can it make on built block with PUMP gas? Give or take?

 

I guess we will have to stick around and see... Jeffs is going to be insane though! 8K!!! of orgasmic sounds

edit: I will cry if he doesnt put out 700+.. im not kidding

 

Same here... Im so lookin forward to numbers on built block... Can't wait!

 

sasha won't know how much it will make because it's never been on a built block. Mine will be the test mule. and my wastegate spring pressure is 14.6 so 15psi is lame. we're talking 25+ psi.


using squirrel perfomance calculator and terry's spreadsheet calculator it's looking like this turbo on my particular engine will still be efficient up to 800whp. Limiting factors would be piping design, intercooler, possibly my cams (although my heads are ported like crazy so it flows a lot). Just because a turbo map says the turbo can do it doesn't mean there aren't other things with piping that change how it functions. We'll be testing and recording all that data though.

So yes, with 93 octane 800hp is still in the efficient range of the turbo itself. Personally i think that's a high amount of hp to tune safely on pump. E85 should be ok to get there and i am thinking probably around 600hp on pump. On a DD the numbers will be lower so i'm hoping to at least get up to 650 maybe 700hp range on a dd with e85.

 

Vas_Z33 Are you running a return fuel system?

 

I will when my motor goes in.. for now stock .. just walbro and 800s

 

jeff, you sell the vortech? ( havnt checked the market place )

 

I have a local wanting it. I'm tearing it off today. If he comes up with the money soon then he'll get it. If he's a dreamer like most are then i'm not holding it for him and it's going up on the marketplace.

 

This is from the research that I have acquired:


One thing you guys will notice is that none of the velocites goes above 304 MPH or 0.4 mach. According to Corky Bell, Maximum Boost pg 61, 304 MPH or 0.4 mach is the point at which airflow meets increased resistance (drag) and flow losses are experienced.


0.4 mach = 304 MPH

2" piping
1.57 x 2 = 3.14 sq in
300 cfm = 156 mph = 0.20 mach
400 cfm = 208 mph = 0.27 mach
500 cfm = 261 mph = 0.34 mach
585 cfm max = 304 mph = 0.40 mach


2.25" piping
3.9740625 sq in = 1.98703125 x 2
300 cfm = 123 mph = 0.16 mach
400 cfm = 164 mph = 0.21 mach
500 cfm = 205 mph = 0.26 mach
600 cfm = 247 mph = 0.32 mach
700 cfm = 288 mph = 0.37 mach
740 cfm max = 304 mph = 0.40 mach


2.5" piping
4.90625 sq in = 2.453125 x 2
300 cfm = 100 mph = 0.13 mach
400 cfm = 133 mph = 0.17 mach
500 cfm = 166 mph = 0.21 mach
600 cfm = 200 mph = 0.26 mach
700 cfm = 233 mph = 0.30 mach
800 cfm = 266 mph = 0.34 mach
900 cfm = 300 mph = 0.39 mach
913 cfm max = 304 mph = 0.40 mach


2.75" piping
5.9365625 sq in = 2.96828125 x 2
300 cfm = 82 mph = 0.10 mach
400 cfm = 110 mph = 0.14 mach
500 cfm = 137 mph = 0.17 mach
600 cfm = 165 mph = 0.21 mach
700 cfm = 192 mph = 0.25 mach
800 cfm = 220 mph = 0.28 mach
900 cfm = 248 mph = 0.32 mach
1000 cfm = 275 mph = 0.36 mach
1100 cfm max = 303 mph = 0.40 mach


3.0" piping
7.065 sq in = 3.5325 x 2
300 cfm = 69 mph = 0.09 mach
400 cfm = 92 mph = 0.12 mach
500 cfm = 115 mph = 0.15 mach
600 cfm = 138 mph = 0.18 mach
700 cfm = 162 mph = 0.21 mach
800 cfm = 185 mph = 0.24 mach
900 cfm = 208 mph = 0.27 mach
1000 cfm = 231 mph = 0.30 mach
1100 cfm = 254 cfm = 0.33 mach
1200 cfm = 277 mph = 0.36 mach
1300 cfm max= 301 mph = 0.39 mach


With my kit I use 2.75" piping from turbo to FMIC, and 3.0" from FMIC to TB.

FMIC is rated to flow 1002cfm. So, both piping and FMIC will flow more than the turbo can put out. I know that there are no flow maps for the 67mm, but we can make an educated estimate when looking at other turbos simmilar size.

 

Nice, can't wait. I was lookin at e85 but found some crazy stuff that the gas is really harsh on the lines n eats em up quick... do u know a lot about it? is it jus fill up n go or does it require modding the pump, lines n tank?

 

You may reach the knock threshold earlier than you expect (depending on many factors)! Be careful. Who's going to be doing the tuning?

 

i hope you didn't take that comment about you not knowing as offensive sasha. I merely meant that you wouldn't know exactly based on not having a car dynoed on it. Math and calculations work out to show this is a great kit. With all the bs floating around the forums lately it's hard to throw out a number until we get my car on the dyno and really see what it does. I personally do not believe piping, ic, etc will be a limiting factor i was only saying that those are factors that CAN be limiting within a kit.

if you get on squirrel performance the map for a garrett 4088r is almost exactly that of the 6765. Evo's use both of them and looking through a dyno graph of the exact car doing a 4088r pull then swaping turbo to a billet 6765 turbo the same day shows that the turbos do almost the same thing except the 6765 rockets up to more power at high psi. based on that i think the compressor map for a 4088r is a very close when calculating.

you need teflon coated lines. CJM fuel system will fix that problem. I recommend a stage 2 but a stage 1 will be enough. My stage 3 is sitting on the floor next to me right now. just came in 30 minutes ago. it's BEAUTIFUL!


RC, i definitely know that. That's why i said 800whp is too high to tune on pump gas. Just because the computer calcs say i'm in the efficient range at 800hp for 93 octane doens't mean i believe it. 800hp is a race fuel or e85. we'll be tuning both for testing purposes.

Hal is doing the tuning. He was excellent on my last tune and i trust his judgement. At this point the only other person i would ever let touch my car would be Sound Performance but i have a Haltech. Vince at r/t is great but too far away for me. It's always smart to go to the best tuner for your ecu anyways in which hal is the standing expert.

 

vids vids vids!

 

You're in great hands for sure.

Sorry wasn't contradicting you - only meant that even if the turbo is efficient and AITs stay low - you can still pump enough mass air and/or adjust timing and/or get the engine hot enough and/or lower octane (etc) to get into knock territory (no fault of the turbo or kit or engine - just physics). If you were going to try it on your own, was going to recommend the headphones. I tried the little circuit published by Jared at Uprev and it seems to work (but I don't claim to be an expert). If you put the little adapter onto your ECU wiring in advance of the tuning session, it'd be interesting to see what Hal thinks of it compared to the pro knock listening devices he has experience with. The wiring is really easy (knock wire is transparent and turns to white and the ground reference is black with a red stripe).

Very excited to see what this turbo kit and turbo combination can do! Best of luck!!!

 

No offense taken, I was just throwing that out there as information. I am not saying nor can I predict what kind of power the car will make. We can all speculate untill dynon day. At that point when Hal runs the back pressure testing (just sent him the suff for it) and IAT testing we will know if this is a win or fail. I am confident that the restults will be good...but again this is my guess knowing the kit inside out, and comparing it to other kits out there.

 

sasha, i completely agree after looking at all the data the numbers are there. It's going to be a sick kit. The question is, HOW sick

Raj, i knew you weren't contradicting me. I think the way i stated it earlier could have led someone to believe i mean 800 on pump. corrected and moved on. I don't know if hal would even attempt that anyways. I'll be happy with ~600 pumpgas. PLENTY for the street. i have e85 if i want to get crazy on the street.

i'll try to get that wired up and see what hal thinks. We have a lot to do and iwll be pressed for time as it is so if we're bored afterwards he might mess with it. During he'll probably just use his tried and true methods.

 

you got ur stage 3>?! niiice!! well since you got that.. and the turbo coming in tomorrow.. and getting dirty with oil ... I sayy.. NEW THREAD! and pix! it should only go like 50 pages

 

ya, i'll post pics when i get it installed then results when i get it on the dyno.
