power difference between these hi-flow TPI pieces

This is what I am currently doing:

ZZ4 with Superram intake manifold, ported stock plenum, SLP runners.

How much of a difference in power woud there be if I returned the SLP runners and then bit the bullet and made it so I put the Superram intake manifold with Superram plenum and Superram runners?

Also, what is the difference between the Superram and MiniRam components?

the mini ram will be able to support more rpms. the super ram will give you a little more low end torque, personally id go with a mini-ram or a stealth ram.

the difference between a high flow LTR and a superram is going to be significant but i could not be exact unless i had done the exact same thing. with the superram you would loose some low rpm tq but pick up the hp across the board from say 4k on.

So the superram is not a LTR setup but the miniram is?

And i found out Miniram is not emissions legal and is not an option. Besides, I already have the superram base.

I am thinking about returning the SLP runners and getting the superram plenum and runners rather than using the SLP runners and ported stock plenum. It will cost almost 50% more, but I wanna do it right the first time. This would also mean no turbulence in the airflow becuase they are matching pieces out of the box.

no the miniram isnt a LTR setup. it has shorter runners than a super ram does, so it will be able to make more power at higher rpms than the super ram.

dam, i am sofa king we todd it.

I have been searching the archives and found that the superram produces the flatest torque curve and most HP out of all of my options. It seems like it is worth the time/hassle/money to return the slp runners and get superram runners and plenum to go with my superram base. ANd being that it is going on a ZZ$ i do believe it is called for and would produce some nice power. Would anyone agree with me?

btw, nice car. it looks exactly like mine does, except i dont have my aerowing painted and put on yet and i took the door molding off.

if you are going to be putting this on a crate engine, look into changing the cam before you put the motor in the car. get a good cam for the super ram like the LPE219 grind. the motor will still be powerful without the cam, but with it will be even better.

Thanks.

I totally wish I could. If it were a perfect world and I did not have to pass NJ emissions, I would swap in the LT4 hotcam and 1.6RR and bolt the superram on top of that. That would be a total beast. But I do have to pass emissions, so the ZZ4 is a nice comprimise between performance and reliablity/driveability/legality. The Superram is just to squeeze everythign I can get out of it.

I am pretty sure I want to go Superram. I just hope that SLP will take the runners back.... they are still brand new, I simply opened the box and looked at them.

Also, where can I get the Superram plenum and runners at a cheap price. They are $764 from Jeg's sold as one. I bought my Superram base brand new from Rich @ Cruzin PErformance at a good price. Similarly, where can I find the plenum and runners at a good price???

L98IROCZ89: How much did you get that base for? Also, are you planning on getting a new PROM? (I also suffer from NJ emissions )

I bought my whole set up from Rich (super ram + base). He will beat anyone out there. He even sent me a small refund after sale and told me he got a good buy on the bases. Make sure you do a search on superram install tips. That thing is a mofugga to install. I think after doing it once though its not that bad. There are some real good techniques here on the board.

I bought the base from Rich through an EBAY transaction... pretty good price if I say so myself (I think he is currently selling on on EBAY now, go search if interested). I emailed him and he gave me a price on the plenum/runners and I think I may get them, depending on how much of a hassle it will be to return the SLP runners.

I live in Ocean Township, NJ and New Brunswick, NJ. NJ emissions really suck. Fortunatly, the ZZ4 is a Corvette L98 (aluminum L98 heads/10:1 compression) with a ZZ4 cam and the Superram DFI is emissions legal. All that put together, I hope to pass.

Right off the bat, I am planning to have the car run on the stock chip. If that doesn't work, or if there is HUGE room for improvement, I am going to get PROM burning equipment and learn. That's the plan at least. I just hope that when this is done, (uperramed ZZ4, aluminum driveshaft, 3.73's, T56) this thing better be fast

The SuperRam sounds like a good idea on a stock ZZ4. You wouldn't need the RPM potential of the Stealthram or Miniram with the cam and heads that come on a ZZ4 anyways.
If you do change the cam someday, don't go with the Hot cam for the SR, that's what I run right now, and I feel it's costing me, others agree. Get the LPE 219 or a single pattern for the best results.
good luck
