Ok dont give opinions lol. Ill just tell you all when its done in a month or 2.

I tuned a 94 with a log and 2560 a little while ago made 240wph on 14psi on crappy 91 cali ****

 

In for turbotims reply, hes been in this thread like 25 minutes so far.

Tim you had better be typing.

Dann

 

To the best of my knowledge, all were at 12psi or more.

If that's Jes maggs (Paul's wife), then that's a 2554, begi "log", my downpipe & exhaust. That would be the only graph with a "log" manifold if you want to call BEGI's a log. It's big, it's heavy, but it's not wood.

Paul's machine and Artieparty were my centered/low mount manifold and exhaust, same as Hustlers minus the Vband/EWG glory.

saintfoo was my A/C P/S low mount manifold (like the above with just a little more offset to clear A/C P/S)

That manifold definitely was not a log, or at least my definition of one. It's much more 'directed pulse' than BEGI's claim.

A better view:




Granted, my second did feel better but I don't have a dyno plot of it apparently. This was my favorite BP manifold with my 2560. This had no pipes pointed directly at another pipe, but the collector area is the same between each manifold.





ScottFW has a vband/EWG version of this.


310rwhp @ 17psi, 304rwhp @14psi. The limits of that 2560.

Probably because it still ran the stock oil pump, not because of the tune or turbo kit. Well, maybe add some inconel hardware.


To answer the OP, I would wait for Trackspeed's turbo kit.

 

buaahwahahahaa you got me!!

 

i thought magg's curve looked different; thanks for the elaboration on my deficiencies.

 

And I think mine is the only one with a '94 block/head/intake (sorta). All the others had some sort of '99 head and some ran BEGI's old cast intake manifold with a 70mm TB...Paul's and Saintfoo's. Artie ran various versions of gutted OEM intakes or not so i don't know what his plot was done with.

 

Either way the findings here show that the flow maps are spot on and that 300-ish is what a 2560 will flow on premium. So Im hoping for 350 on E85.

Would that be some sort of record?

Also we will find out how far the stock 1.6L IM will go with stock TB. 300 so far.

Dann

 

I'm pretty sure 350 on a 1.6 and 2560 will be some sort of record. Esp on stock head/im/tb.

 

i dont see it happening. that turbo is TAPPED out.

Like it got hit with the Tranny Press.

 

True on gasoline. But E85 has 12% more torque potential and that's 36hp alone at this rate. 310+36 is dangerously close to 350hp.

Dann

 

but its well outside it's efficency range, e85 be damned.

it's all about the floooooooooooow.

look at the difference between 14psi and 17psi. 10hp, but gobs of midrange torque...the thing is tapppppped out.

unless you fit it in a .86 a/r housing, i dont see it happening; just a lot of hot air.

 

lol yeah, I don't think you get how this works man: e85 doesn't magically add flow capacity to your turbo. Once its tapped out, its tapped out. You'll squeeze maybe a couple more hp by running insane timing, but once you're off the maps, you're pretty much done

 

especially since both the compressor AND turbines are tapped out.

 

+1

 

I think you have forgotten that the energy potential of E85 at stoich is 12% greater than gasoline.

This car went from 255rwhp to 280 just by switching to E85 without adding any more boost.

If 310whp can be done on petrol 340 can definately be done on E85 on the same setup.

Dann

 

lol ok try it

lolol

 

I cannot believe you genuinely dont believe that E85 has a higher energy output than petrol at stoich. You played with E85 before? Come on 18, you are clevererer than this.

Dann

 

You serious?

I have been tinkering with e85 for years now. Tuning subarus and evos, and a few miatas too (including my own).

I'm not even discussing its energy output with you, so I'm not denying or agreeing with that statement because frankly it has nothing to do with this.

I'm saying your turbo is TAPPED OUT at 300. This has nothing to do with e85 and everything to do with your turbo and setup. IF you still don't understand what me, brain, and savington are saying, I don't think there's even a point in arguing something so retarded.

if you had a well breathing exhaust, good manifold, and spiked the timing to kingdom come, you'd STILL fall short of a true 350whp on a 1.6 with a 2560.

You can call me an idiot, but I challenge you to prove us wrong.

PS: Sav has tuned more miatas than most of us put together. Ask him if you don't believe me.

 

I do challenge you and will build it in the coming month or 2.

It doesnt matter what the turbo will make on one fuel if another fuel has a higher energy output. Flow maps are in airflow, not horsepower, and without knowing the efficiency of the cumbustion chamber (lol, rubbish) and the specific energy output of the fuel theres no way to convert flow to power which is what you are trying to do.
