My Dyno Numbers

[michaelgt]

Hi everyone I just dyno my mustang does this look right it's a 1989 Mustang GT 5.0 5speed manual transmission it has Pro-m 80mm mass air meter Anderson Shorty Power Pipe 65 throttle body Holley systemax intake manifold upper and lower 1.7 rocker arms 24 injectors BBK shorty headers Dynomax super turbo mufflers with pipes 190 fuel pump timing is set at 12. 355 rear end gears aluminum driveshaft the car still has AC stock 4 cats mishimoto radiator 3 core 180 thermostat NGK spark plugs iridium 229HP 272TQ stock heads. Stock Cam

Yeah those numbers look about right for what you have going there. You have plenty of intake ect., but the stock heads are a bottleneck and the 4 catts are very restrictive. You could possibly pick up 8-10 more if you bump the timing on up to 14 degrees.
If you get yourself a nice set of heads and maybe a cam while you're there it'll be well worth it.

good luck

@Onefine88 thanks for the reply do you know what cylinder heads will work for my setup and be 50 state legal?

 

[Onefine88]

I don't know about 50 state legal but I have the same intake as you. Under that I have a set of Edelbrock Performer RPM heads and Trick Flow stage 1 cam. That combo made 300rwhp and 330rwtq. Now I have a supercharger on the mix so it makes a little over 500.

Those numbers are what I would expect for your mods. Trick flow 170cc and AFR 165cc heads are both legal options. Finding a cam is a little more complicated.

Can he consult with a cam grinder for something that will work?
I don't know what his end game is.

Plenty of head choices that are Smog legal. Trick Flow, Edelbrock, AFR..... just depends on how much you are willing to spend.

 

[RangerJoe]

AFR 165 heads, custom cam.

[michaelgt]

Thank you for all the replies my goal is to have 500 but California legal I would like to have cylinder heads flow as much as possible but be California legal and a cam if I could get one I would be super charging this car of course it has to be California legal

 

[liljoe07]

Going to need a lot more than just heads to reach your goal reliably.

 

[RangerJoe]

For 500 smog compliance HP, you probably need to look at a vortech blower or a larger, we'll thought out cubic inches build.

Joe

 

[michaelgt]

Dang maybe it's too big of a order how about 450 flywheel with the vortex supercharger 5-8pounds of boost and Edelbrock cylinder heads?

 

[RangerJoe]

I think 500 is easily doable with aftermarket heads and a blower.

Joe

 

[michaelgt]

What cylinder heads and what blower?

 

[RangerJoe]

AFR 165 or TFS 170 with a custom cam and this:

I'm looking to get the AFR heads 165 do I have to do anything to the Pistons my car has the stock Pistons and will a e303 cam work I think that cam is California legal??

 

[RangerJoe]

Your factory pistons and 165 heads will work fine together. The e cam will work, but I am unsure about the emissions side of it. A custom cam is more exspensive, but will meet all your goals more easily.

I would suggest larger injectors, larger fuel pump and a dyno tune when it all goes together.

Thanks for the info the e cam has CARB EO Number: D-225-16 if I use this cam can I use the 1.7 rocker arms or will I have to get 1.6 rocker arms and what injectors and fuel pump??

 

[RangerJoe]

I would stick with the 1.6 rr. 42 lb injectors and a 255 pump should suffice.
