I've heard that 390hp is about the most you can get out of the 13B-rew using the stock twinturbo, is this true?
And what is the easiest way of producing about 350 hp?

 

Maybe 390 to the crank.
Intake, Down Pipe, Midpipe, Some sort of Fuel Management, Intercooler, umM Fuel Pump, there is no CHEAP way on doign this unless you buy all the parts used. Ive heard 330-350 to the wheels max on the stock turbos (if you dont go above 15psi which is when they lose their effiency).

 

And wait until they grenade on you! Mine did last 1 year at 15psi.

 

What ecu were you running?

 

just do my whats in my Sig.... i have about 360 to the crank....

 

So the catalytic converters are taken out of the car?

 

I know a few years back there was a FD with the stock twins that dyno'd at 383hp.

 

To the wheels?"!

 

odditysmurf made 398RWHP with a STOCK MAIN CAT with 99spec twin....

 

Im guessing they must have really good effiency a bit better than the stockers.

 

i know someone who made 387rwhp on the stock turbos, ported motor, full exhaust, ic, intake, pfc, larger injectors, fuel pump. it made 380rwhp with a modded stock airbox and a stock mount greddy....

 

Are all these dyno #s corrected? what did they trap in the quarter? In street trim, on stock twins, any more than a consistent, reliable 350 to the ground seems very fishy to me.......

 

a friend of mine made 355 on rx7store's dyno, and 359 on the mobile dyno at the rx7 revilution at 13psi. stock (orignal) motor, non syq twins, intercooler, full exhust, intake.

 

Odditysmurf was running 20psi on race gas and a fairly large street port

it was for dyno brag

 

Everybody says I heard, well I have heard lots of stuff but never neen it. I have seen a number of actual dyno results and never one that made the power I hear on the forum.

Also you can tune a car so the dyno graph looks like a pyramid. For driving the car would suck but to brag you could say you actually put out that kind of power.

What are we interested in peak numbers no matter how it is tuned or real numbers tuned where the car pulls in the lower end like a V8?

P.S. Look at Just got Dyno results to see how I prefer my dyno numbers to look and compare that to anything else you have actually seen.

 

I have a DP, MP, CB, Greddy 2Row, Apexi Intakes, Walbro 255 pump, 850 primary and 850 secondary running in parallel with each other. So when the sec. kicks on, the primary does not shut off I just got my car back from KD and it dynoed 347RWHP at 14.5psi. I'll try and post the dyno sheet.
