My torque curve is more like a Penrose Triangle than your poser "flat" curves.

 

my torque curve is like hustlers ****: short and peaky

 

Or perhaps curved...

 

I'm a noob at figuring my HP so its guesstimation time for my 2001 :

I'm running XEDE and a small IC, a BEGI log to a 2560 to a BEGI SGDP to a stock cat and resonator with no muffler at 12psi.

Any guesses to my whp?

I know I should dyno but I'm cheap and still adding the exhaust so I'm in transition time and I'm going by AFR's to be my safe tune guide right now

Im buying a 3" DP back system with no CAT and a magnathrough, what should I be for HP then?

In both cases I have tuned for a bit of safety more than power so consertave guesses are welcomed.

 

low 200's

 

What will the exhaust net me:

Figure: Stock DP back ----> 3" no CAT & magnaflow


maybe 30 hp ??

 

probably something like that with a good retune.
I remember going from stock exhaust to 2.5" all the way back on my hks setup.

I was like OMFGWTFBBQSOUS

the power/spool increase was surprisingly big

 

I can't wait to get one installed, going to be great ! - thanks

 

Since this threads been bumped, I'll jump in.....

It is grand. They don't know what hit them. I'm now actively looking for a late model Viper or ZR1 to roll the dice on. The car might get a bottle with a tiny 100-125 shot "just in case"

 

Damn, I need to get my car done. 310 WHP should be fun.

^Also considering a 100 shot but the little used 6 psi vortechs are soooo cheap for the 5.0's.

Been having so much fun on the track with 110whp (on 520lbs wet weight, lol) that the Miata has been neglected. Got another trackday next Sunday.

 

I am at 12psi w/ a begi S6 on a 2860rs. Full 3" catless exhaust. I don't know how much whp I am making, I am assuming it's around 250whp. I drag raced a 2010 Camaro SS (426hp) on an 1/8 mile, and beat it.

 

Probably not quite that much, but it will sure feel like a lot, and you will seriously walk around for two weeks afterwards punching yourself in the face for not dumping the stock exhaust sooner.


Good to hear you're enjoying that thing. I'm looking at an old F3 track beater to get a little more out of track days than I'm willing to push the VFR for.

 

200 rwhp sounds slow.

Double my current HP, yes please! My goal still remains after all of these years, at around 220-240, maybe 250 just to round it off nicely.

 

And this is why I went 3" turbo back straight pipe

 

This is why you go 3in all the way out and open WG...with no muffler YEAH BABY



I have no clue where im at power wise. Im guessing the 280 on a mustang dyno mark

 

embed fail

 

fixed

I was messing with my boost controller yesterday and for some reason I was only hitting 12 psi. God it felt so slow. lol
