what rpm produced 8psi/when does the car start moving?

Stephanie Turner

I wish we could. I go to CT alot, so if I was in the area it would be no problem. But I have a gymnastics meet next weekend.

The dyno is at 700 ft elevation. The office is at 1400 ft.

wow, those curves are very close after 4200rpms.

For them to be that close, I'd take paul's - I love having a lot of power down low - it doesn't really make it much faster, but it's a lot nicer to drive around town like you have a V-8, cruising 3 gears higher than you should be...

It's a lot nicer for tight autocross courses as well. I think this thread helped me make up my mind to get the 2560r over the 2860rs.

Braineack

the compressor wheels are the same, so you should expect similar power. I bet if it were the same motor and spark map, the 2860 would simply make more power up top, but you'd see that sacrifice of low-end, which isn't a big deal. Like seen on Jeremy's car: http://www.flyinmiata.com/tech/dyno_...emy_potato.pdf

That's what gets me - something with that much of a turn off on the top end should have a lot of bottom. I wonder what boost as a function of RPM was... Maybe they were in a really low gear on the pull compared to paul.

To me it seems like they should have top-end, but then again, the engine management isn't ideal, is it? Restrictive intake?

Got me. I just need to tune my car. Sometimes it runs well. :-P

Doesn't Paul have his super-pimp custom made manifold? I'd like to see him toss a Potato on that car and see what it does compared to the 2560.

Braineack

iTrader: (62)

no, that's a pretty typical comparison. both will make similar power, the 2860 will spool slower but make more power per psi.

the turbine is .8mm larger and a 76 trim vs. a 62 trim

chriscar

That BEGI dyno was at 13psi, how much was Paul running?

C

Braineack

iTrader: (62)

14psi IIRC.

chriscar

iTrader: (24)

Yeah, 1psi difference. Does the gt2860rs suck that much? You really think that putting a 2560 on the Begi car will result in the same curve Paul has, or visa-versa?

C

Braineack

iTrader: (62)

it's just a turbo for a different job.

Again look at this comparo. this was the same car and same boost: http://www.flyinmiata.com/tech/dyno_...emy_potato.pdf

while it lost 500rpm of spool, it gained 10hp/10tq. probably runs a little cooler as well, so better for track days where you dont need that extra low-end and can use all teh heat management you can get.

paul also has a 99 head with some work done to it I believe, right?

paul

iTrader: (21)

the car in question is an 03 so it has the same flowing head and no, my 99 head is stock.

lets see what i can do this saturday. busting my *** getting this set up
