What power could a b18ft be at with gt2871 tubular exhaust mani megasquirt and a posh cam?
At what boost? 260hp should be doable when mark does his we will see what can really be had.
I have gt2860, rsi cam, log mani, megasquirt so when its mapped il let ya know what it makes and that will give you a good idea.
Say 20/25 psi. Who's mapping yours mate?Quote:

Have you got a link to the megasquirt you have? :) Is the your base map something you did yourself on a laptop? Not really in touch with standalone ecu's :crap: thats a shame i hope he can do mine when the time comes. what power you hoping for?
I got mine off eBay its a ms1 v3 yeah had nothing with it so had to download some programmes and make a map. Looking for 230hp anything over is a bonus. I don't know much about them either but it seems to be working:laugh:
Check out my specs on my profile.. made 227 at scoffs, not bad for a "budget" build, still want more tho
Would this work?

Whats it like on the base map?
What ecu are you on reggy?
standard ecu and a bypass hole? You can get good power with std ecu's but I couldn't get mine to fuel right all of The time. The bypass hole is to trick the maf so it thinks the enginebis getting less air than it actualy is until the maf hits 5v then it makes no difference. I had mine like this for a year or so and it really went well, you can allways upgrade to standalone at a later date anyway.
Schwartz, whats the purpose of the bypass hole? giving the engine more air than is meterd would surely make it run a little leaner wouldnt it?
As far as i can remember, mine doesnt have a bypass hole.
If you're using std injectors or Volvo green ones you don't need a bypass hole but prob will only fuel for 1bar on a big blower. When using t5 orange or Saab reds (what I have) it will be way too rich off boost so the bypass hole leans it out until the maf sees to much air and dosnt make anymore changes anyway then you lean it out with more boost:D mine was still in the 10's at nearly 2bar boost and a megasquirt came up cheap so I went for it;)
So I could use a gt28 and Saab reds on standard ecu and make 1bar with what size bypass hole?
Cool, ive got an E or EP cam in already and some saab reds sat on the bench ready but i cant do anything until i get a t28 on there.
Thanks buddy

Running standard ecu and as Schwartz says it's quite a simple job to gain good power, going to look into standalone next to get better results as scoff said it was still making power up to the standard ecu limiter
I think the magic number is 32mm bypass hole but I just kept trimming it until my afr readings were good all round.. a little tweak of the atm is normally required aswel but is an easy job, haz is a good bloke to speak to regarding these enginesQuote:

I was running 1.8 bar most of the time with Saab reds 32mm hole is normally about right then turn the maf to 650ohms iirc using the brass screw under the cap and a multi meter on the two outer pins to read it.
I have set mine to 7000rpm limit at the moment to be safe as its not mapped yet but the bottom ends are solid I would speak to mark but 8k would probably be fine.
What were you making before you went standalone? That's really good could there be room for a turbo bigger than a gt28 with a 8k limit?
Never had it rolling roaded but it was quick. I have a 2860 with the larger .86 rear basicly a ball bearing version of a pulsar turbo I get full boost by 4k so much bigger prob wouldn't be good for the road.
