Can only work with what we've got.......

Umair , it was great to get your info, what I meant , if it had been the 6266 it would have made the 8374 low end response look even better , but I think the top end would be pretty close with both turbos

Umair,

I took the liberty of converting your results to excel and graphing them vs my pumpgas results (including corresponding boost curves). Looks like my combo of stock-bore 79mm stroker (2.75L) and/or the .92 IWG housing turbo is making a bit more bottom end than yours (below 4500 rpms), but obviously with higher boost and E85 you're crushing me anywhere over that. The boost is x10 for scaling purposes (ie 100 = 10 psi, 200 = 20 psi, etc). I'm willing to bet when converted to E85 and when I start pouring on the boost that I will make more power lower in the rpms, but not significantly so (maybe 250-300 rpms sooner), and with the increased backpressure of the .92 housing I'd bet I'll start dropping sooner as well.

Good looking dyno! :1311_thumbsup_tone2:

Not really surprised there though. Bigger engine making more grunt down low.

How long till you put it on E85, Harris? 

Station is targeting completion in november. I'm hoping to have fuel pumps, 3.5" exhaust, and mega huge injectors done by then. I'm still on stock fmic so we will see what it can flow!

will need 100m cooler. the stockies have been known to hold power back over 400kw.

3.5" will do the job. Mine is 3.5". 4" only if you know you are going to aim for even bigger power in the future.

My injectors are 2000cc. I was told that even 1600cc on e85 wont cut the mustard for 500kw. Makes it a little harder to fine tune but its not noticeable in day to day drive.

thanks for mapping the dynos. interesting stuff!

If anyone is interested, I'm maybe going to the SAU cruise to the Gosford car museum on Sunday.

Happy to take anyone for a spin so they can feel the setup for themselves.

What about me? Sounds like he's got a cooler.

I'm almost tapped on money these days (oilfield sucks here lately). I need a sponsor!

haha but you're in the US.. shipping won't be cheap.. however happy to help out - flick me a PM on which size cooler your after, and if polished/black/raw etc..

What wasn't factual in there? 

You must have some EFR experience to share with us if you know there was nothing factual in there? 

 

 

at the end of the thread which got it locked .

    • He could just take the Bogan Cruise Ships setup... Already got a good setup, with blower, the auto was rebuilt too wasn't it? Perfect time for him to upgrade the tailshaft, diff, and axles...    And wouldn't need to waste money on redoing the Commos seats, as he could just buy race seats for the 5...   As a highly modded car he could avoid the ability to give it away to offspring too when they crash their cars...
    • It's really interesting how much it's moving left to right, and doesn't appear to be actually spreading. For this to be moving left to right, without flaring, means unequal forces being applied until equilibrium hits in one way or another.   Reasons it could be unequal; Piston sizes left to right are different sizes. Only minute differences. Pistons moving on different planes. That is, are they moving directly straight at each other, or slightly out of alignment. The fluid is restricted getting to one side.   Some tests you could do. Pull the bleeders on the left and right, fit each side with pressure gauges. It will allow you to make sure pressure is equal (and really, it should be as fluid flow is so damn low, so fluid flow dynamics shouldn't come into it).   With the calipers off the car, have both sides retracted as far as possible, measure very very accurately (think micrometre) distances between opposing pistons in four different spots per set of pistons. Firstly, on each opposing pistons pair, the measures on for different spots should be equal. If it's not, and especially if one spot appears to actually get closer compared to another, the pistons aren't aligned, and now the forces left to right won't be equal, as they're the forces fighting each other.   You can also pull all the pistons out, and very very accurately measure the diameter of them. If they're not equal left to ight in the pairings, and especially if the area of the pistons on one side is different to the area on the other overall, it'll all be out of whack.   My bet, is shit QC in making sure the pistons move in the same plane left vs right. Some minor out of square machining, and nothing will line up, things will want to move around.  
    • Whilst putting a V8 in a MX5 would be fun, it would negate the whole cheap to run fun daily that the MX5 will be used for If I wanted a faster little convertible I would have got a engine check light, I mean a BMW Z4 M, but going off the issues that the guy at work who recently got one is having, it is lucky I didn't  Meh, horses for courses, the Bogan Cruise Ship is my go to for some horse torques    
    • I reckon give him a few months, LSX swap would be good
    • Mark needs to get bored at work and order things on here...
