I picked up a extremely low mileage flowzilla with the blowzilla inlet and gt40 intake setup. The plan is to do a cam and head swap, new water pump and aluminum rad while installing the supercharger. Now I am trying to figure out what injectors and MAF I will need as well as other miscellaneous things that I may overlooking.
Please, any and all advise is welcome.

What year engine?
Sorry the car is a 1995Quote:

Very good information. Keep it coming [emoji4] I may do a full rebuild while the engine is out. Should I go with forged pistons? If so did any 5.0 come stock with forged pistons?Quote:

I believe the 1987 to 1992 mustang 5.0 engines had forged pistons.
...treed, lol.
Yes older engines use forged pistons, but if it was me I’d go 10 psi max even with those. As far as injectors you’d need to know what psi you’ll be running and what power level you’re expecting to be at, 36-42 lb/hr is probably what you’ll end up with, and you’ll also need to upgrade your fuel pump.
Stock 302s with forged pistons can be had cheap ($200?) may be best off to buy a used engine and build it on a stand then swap it in.
Likely what I will do :) I will have to sweet talk my wife into believing it was her idea thoughQuote:

Conservative boost + safe tune play well with hyper pistons.
had a blozilla on my 86 made great torque like 450f/t at only 6-7psi boost with the 19lb injectors but had to convert over to Mass air.
That was such a nice Fox!!!!!!!!Quote:

I am planning to run 6lbs and a very safe tune. I don’t need gobs of power but would enjoy the added instant torque.Quote:

I wish I bought that car all those years ago, oh well.Quote:

Yes thanks for the heads up!!!Quote:

The Autotune feature works fantastic, my '86 never drove so well with a mass-air conversion naturally aspirated. No chip, no retune with a tuner for every change. Still learning the system but getting there, lots of control.Quote:

It's complicated, yet fairly straightforward at the same time...if that makes any sense. My biggest hurdle is getting a steady low idle speed, which may be the cam and the ancient idle air control motor I'm dealing with. Driveability is fantastic even with the batch fire fueling, no complaints there at all. Boost tuning has gone well, some street tuning and a few track visits got me pretty close, and I haven't really touched the timing tables yet. I'm pulling huge amounts under light boost.

I will likely go that route next year.
For the time being would I be able to run the car essentially stock with the blower at low boost?

Here is my recipe lol.Sct 2600 mass air, sct chip, b-cam ,255lph fuel pump 44 # injectors ,tfs heads, gt 40 tubular intake on a 92 block ,10 pounds boost on a safe tune car made 483 hp 447 torque.
Probably the best choice. If you factor in things like a chip and tune. The megasquirt is a no brainer. Also the price guys are asking for A9L the megasquirt is a better choice.Quote:

Does anyone know if there is a table to figure out boost from pulley size?
Sent from my iPhone using Tapatalk
You can estimate any boost level with the following formula:
((Crank pulley diameter/blower pulley diameter*blower displacement/(engine displacement/2)*14.7) - 14.7)*Volumetric efficiency
Volumeteric efficiency is about 90% typically
Example: 5L motor with a 1.5L blower, 6.5" crank pulley and 2.62" (2 5/8) blower pulley
((6.5/2.62)*(1.5/2.5)*14.7-14.7)*0.9 = boost in psi
boost = 6.46 psi
same motor and pullies with a 2.2L blower:
((6.5/2.62)*(2.2/2.5)*14.7-14.7)*0.9 = boost in psi
boost = 15.65 psi.
Awesome. So with my current 2.5” blower pulley and my 6.75” crank pulley I would be making roughly 18lbs Of boost. :s I think I’ll be buying an underdrive crank pulley

I'd go the other route and up-size the blower pulley. Reducing the belt contact area on the crank pulley and a small blower pulley can get into potential belt slippage territory. Keep the stock crank pulley and throw a bigger blower pulley on and that'll help maintain the largest area of surface contact for the belt on both pulleys. That should relieve some stress on the belt and give you a good chance at not seeing much belt slippage under load.
^This is the best option as long as you have adequate hood clearance to clear the larger pulley.
Ordered a 255lph fuel pump and 42lb injectors. I hope that was a wise choice. https://uploads.tapatalk-cdn.com/201...597b72acfb.jpg
Now I am debating which way to go about tuning this car. Mega squirt or otherwise. I need the car to be drivable and pass emissions. I’m not looking to have the fastest car just something fun for the street.

That will be plenty. Not sure if it works on the jellybean cars, but back in the day fox guys had good results using a tweecer.
Tuners absolutely have a handle on tuning them these days. Add an SCT MAF n your all set.
Just the maf? That simple. AwesomeQuote:

There was a purple jellybean here with a tweecer ....not sure if it ever ran correctly. May have been user error. :stickpoke:Quote:
