Build details in sig. Whatcha think? Keep in mind that this is a dyno dynamics dyno. They said that it generally reads 17% lower than a dynojet.



EDIT: 95, MSPNP, 1.9L 99 head, 550's, 949 racing twin disc, 6-spd, gt2871, 9:1 Wiseco's, M-Tuned Rods, ARP Head and Main Studs, ACL Bearings, BE OPG'S, ATI Super Damper, HDHTDCDD, DO WI

 

How much boost?

I like it. Allot. Definitely time for an intake manifold though.

 

seems to spool up a little slow for a 2871, what manifold?

 

17psi maxing out my 550's

 

niice

 

Begi cast mani

 

I've been out of the game for a while. What's the best option for an intake mani nowadays?

 

modified honda mani.
or one of the members (psi somthing) makes them now.
or make your own


You need bigger injectors too. ID1000's or DW800's would be great

 

man I would love to go for a ride in a Miata that makes 250+whp...congrats man, build looks tasty.

 

Looks good but needs absurd flow and an intake mani.

more like 12-15% low unless their correction numbers are jacked...which they probably are.

 

Gotpsi intake mani and better exhaust mani

 

do you have a fuel pump?

 

Yes. Walbro 255

 

What is your exhaust? I spooled dick when I had stock exhuast.

 

And were you running WI?

 

I have a 3 inch exhaust with a flowmaster chambered muffler. Devils own water injection

 

Get rid of that flowmaster and get something with a straight through design. Those chambers are horrible for flow

 

K, now I get to make fun of you. Get that POS muffler off the car and replace it with a big Magnaflow. Something you can literally roll a tennis ball through, please. There's no excuse for torque that doesn't peak until 5200rpm like that - you should be able to move that entire chart down 700rpm with just a muffler change.

Also, find a dyno operator that knows what he's doing. Starting pulls at 3500rpm =

Fix those two items and you should be able to see full torque in the ~4000rpm area, especially if that's a .64 A/R 2871R. Regardless of what the actual torque numbers are, just the torque line vs. RPM is pretty poor, and I bet it's all due to muffler and dyno operator error.

 

I have seen big horsepower cars use the Edelbrock Super Victor.
