How did this ever turn out for power?

anyone have current updates?

also i would like to have altitude added in. My testing will be at around 4000 ft which will show less than anyone at sea level.

just need a wideband

Only Updates I have are as follows:

216 WHp = 63% Duty cycle on 4 - 460 cc/min injectors on Peak and hold (14.16 V from alternator) giving 13.3:1 AFR. This comes from my Haltech data logging while I was on the dyno making 216 WHp. This is very comparable to online calculators.

I still think that 200 WHp is attainable for you, you have a better intake setup than I do (although mine had been heavily modified from stock). This should offset the altitude difference (I am at 800 ft).

i really need to build an engine for the car. The original 200,000 mile 6 port engine will die sometime.

It might last longer than you expect. Mine is up to 245k now and still running strong.

knowing my luck that is true, but it wouldnt hurt to get something in the works.

only 19 days til idaho. I am going to take on some changes once i get to working on the car again. Primarily going to CAS and having ignition control. Additionally, i am going to get a wideband so i can properly tune the car. otherwise its just guess work.

What kind of port work did you do?

How are you actuating your 6PI?

That manifold that you used has to flow better than the stock 6-port manifold, maybe you can get 200 WHp. I am really convinced that the biggest problem with 6-port blocks is the late intake port close and the second biggest problem is the intake manifold.

The third problem is the tiny primary ports. If you use GSL-SE end plates you can use a Y or nitrided R5 intermediate plate, but then you have to use pre-'86 rotor housings.

my current engine is 100 percent original s4 6 port. I need to build something more suitable.

You have an aftermarket intake manifold though, right? That has to help your power, there is not much worse design than the factory s4 intake for power.

yea its aftermarket

Ok, maybe I am missing something, but what makes the P-port expensive?

All you need is a set of housings, some aluminum-ceramic or Devcon and a hole-saw.

Then you can fill your side ports with iron-ceramic or Devcon and you have a P-Port.

I doubt that you would need a 2-piece Eccentric shaft, etc. for a 250 WHp build.

eh, i guess homebrew wouldnt be soo bad to try. hmm now my gears are turning. i wonder what the limit of my ITBs would be.

im thinking about buying a drill press from the local industrial surplus place, and aside from other things, that should be able to handle some p-port drilling so i might say hell with it and experiment.
