which intake? TPI, LT1, Mini ram
Hi,
I have a S.C. 89, 383 with a SLP, big mouth, ported plenum intake system now.
I make some good street HP# but am considering the next step.
My intake system is droping off at about 4700.
A mini ram costs $1500+
A LT1 Conversion is like $400+
Does anybody have real data for increases for doing a swap from a TPI.
The S.R. is real popular, but I am partial to the cosmetic apearence twards the LT1 and MR.
Thanks for you input

Is the MR that much better than the LT1?
there is like $1000 dif.

I'm not sure how well this applies to FI applications, but here's the best article I've seen on TPI intakes:
Ten Times the Torque
I've got a miniram waiting to go on my procharged application. I figure the boost will more than make up for the loss of low-mid range torque while it will breathe better up top.
P.S. - the miniram and LT1 will perform similarly. The mini has slightly longer runners and an "air gap" for a cooler intake charge, but I bet they dyno the same. Don't underestimate the cost of the LT1 conversion - it will nickel and dime you (custom fuel lines, fittings, small-cap dist, remote coil, remote thermostat, etc.). The mini is a much easier/cleaner install and IMO worth the extra price. You can find them used for about $750 on occasion.
