I am planning a blower/turbo engine project for my 87 IROC and need help from you guys. I recently read a post which indicated that a TPIS Mini Ram has some type of distribution problems in a forced induction application. I know that Guido and Blown406Bird are running Mini Rams - any input would be helpful. I am running the Fast Burn heads, so my intake choices are limited to the Mini Ram, GM RamJet, or a 4 bbl. intake converted to fuel injection. Also if anyone knows where I can get components to perform the 4 bbl. conversion (i.e. 4 bbl. throttle body, fuel rails, etc.), please let me know. Thanks

 

yes, it has its flow problems, but you can make that up with DFI and its Variable Injector Controller.

you can get everything you need from kinsler fuel injection for the conversion

 

Im thinking of upgrading to the Accel intake when I switch heads next time. Im thinking of an AFR220 head with the accel intake and an elbow mounted to it for a TB.

Do you think the miniram ports would be big enough to open up to the size of afr 210's. I have the mini on my 190's now and want to go bigger. Im kind of skeptical to the size of the mini being big enough.

No. I wondered the same thing and I called TPIS. When you bought the mini ram they asked what heads you had right? Well, if you had called and said you had AFR210 heads, they would have sent you a mini ram that was cast a little differently to incorprate a taller port into it. As it is now, you CAN use what you have but you need to weld the outside of the port, and report it to match it to the taller port AFR210. You can buy a new version or switch to something different.

 

Guido - are you switching to the Accel Super Ram or the "converted" carb manifold? Is this decision based on distribution problems or just the port mismatch issue? The post that I remember mentioned something about (based on TPIS recommendations) welding some sort of baffles in the intake to prevent the front cylinders from receiving the majority of the airflow with the stock Mini Ram setup. I would think that this type of problem would be difficult to repair with tuning alone, even with a DFI or Speed Pro setup.

not really, DFI has the VIC (variable injector controller) to help change the pulse, i think, of the injector to make up for this such problem. i think it is +/- 15%

also, with the speed-pro, you can get individual cylinder fuel control w/o a sequential setup and would allow you to correct for certain cylinders

 

Thanks for the info - I thought you had to have the sequential option to tune individual cylinders. Also I called Kinsler today. A 1000 cfm 4 bbl. throttle body is a cool $650. Ouch !!

Try Lingenfelter, Electromotive, and Accel.

 

The only problem I see with the VIC is how do you know youve got it dead on? Sure you can guesstimate but you will never know unless youve got a pyrometer on each header tube.

Im not talking about the SUPER RAM its the Pro Ram. designed for EFI and like a carb intake. Good for dry flow and equal flow to each cylinder. Just fab an elbow and put my 58mm TB on there!
