Putting a supercharger on a mass airflow car
Seems what I remember its perfered to use a car with.a map sensor instead of a mass airflow when supercharging. Am I correct or getting mixed up?
If I can use a mass airflow do I just put the sensor on the inletside of the charger?

Thanks, that makes sense. the more I think about it the more I think im getting confused between ford,chevy.

Re: Putting a supercharger on a mass airflow car
Ideally you want it on the outlet side to measure air mass and do the fueling. If not using an fmu or some hybrid efi system where fuel is added via map sensor. Problem is stock tpi sensors practically max out around 280-300 whp so you dont get much room for fueling, however if boost curve is linear enough like in centrifugal blowers for the most part, you can add fuel via power enrichment vs rpm table in stock code

My setup is on the outlet side of Supercharger.

Re: Putting a supercharger on a mass airflow car
I really want to do a supercharger on my TPI, but I don't want to well, blow my engine up. I have done some research here and there over the years and alot of people say the factory tpi can't handle the power of a supercharger. What did you do to your fuel system to accommodate the supercharger?

Re: Putting a supercharger on a mass airflow car
Yup 7-9 psi will be on par with a bolt on ls1 fbody as far as performance goes
Only things you need to do is give it fuel and pull some timing. Depends how you set it up whether you want fmu or a 2-3 bar map based system or a larger maf like blowerworks
Simplest easiest would be an fmu and get new injectors. High pressure walbro fuel pump is fine.
Only other thing i'd recommend is fresh valvesprings

Re: Putting a supercharger on a mass airflow car
I figured for my project I would need to keep it to under 10 psi into my stock 305 tpi. I also plan on a superram.
My plan is some kit like the vortech one or other. But finding them is a pain.
What approx value on a complete kit. Im figuring $1.5k from what ive seen.

More like $4k. Then there is the amazing amount of stuff you won't have budgeted for: new, bigger fuel pump, new injectors, chip, transmission upgrade, Boost retard box etc.
It is a lot of work and very expensive BUT worthwhile. Just.

Hey if you find any for that amount, let me know - I will buy 10!!

Re: Putting a supercharger on a mass airflow car
Bought my Vortech S-Trim kit new in 1997. 5.0-5.7 TPI same kit. Now discontinued. $2700. Kit was for a stock TPI engine. Many mods later it is still on the car. Going strong, never had a problem with the supercharger.

Re: Putting a supercharger on a mass airflow car
You can use MAF or SD for boost. SD or MAP is just easier. You don't have to worry about getting the MAF installed in the charge pipe. Don't have to worry about location to a BOV or meth nozzle etc. Then you have to worry about the max flow of the MAF and what it can handle. This is why I went SD and it's been great. MAF is more accurate at reading actual airflow and proper fueling, SD is based off tables and the engine is guessing due to sensor input and pulling from the tables.
Good luck finding a kit for 2k with everything you need. I've seen some used kits go for like 2k but they are far from complete and the TPI is different than a cheap carb application.
Swap pump, injectors, tune, other fuel system components like fun, or boost referenced regulator and set it at 6-8psi and enjoy. You should always swap valve springs as your now fighting the charge intake pressure. Hope your exhaust is up to
Sniff with getting rid of all the added exhaust/power.
