holley mid rise fitment
holley mid rise fitment please don't tell me to search. i have been searching for the past week and all i find is old threads with little to no pictures. im building a 99 camaro z28 with a 6.0 iron block with worked 243 heads 10.5 10.7:1 compression pump gas and race gas tunes no e85. running borgwarner s480 80mm with t4 flange. precision 66mm waste-gate on truck manifolds. this is a street build so i don't want to loose the wipers. living in Miami that's a big no no. any input or pictures will be greatly appreciated. also some input on the cams choices what are your thoughts. i was thinking of running btr stage 4 or the 388ci turbo cam on this set up. running id 840s and along with the dual ti fuel pump 450lph e85 compatible pumps Aeromotive boost reference fuel regulator.
thanks in advance...

I'd skip the Mid Rise. Makes similar power and torque to an LS6 manifold, and isn't even close to being worth the cost and hassle of the install. It should only ever be considered as a show piece and not a performance piece, same as the China fabricated intakes.

i already have the intake. its the first time i see some one say its not better than the ls6. i know they all make good power down low. but the mid ram flows best up top. i have a repaired ls6 and didn't want to risk blowing it up. ls6s are going for 450 500 without rails or tb ext. the holley efi was 680 with rails. so i didnt see it that bad i had a victor jr before and killed the low end completley these supposedly flow better. the look is also sick and was one of the reasons why i chose the intake it wont be an all out show car but something nice and decent i have seen people flying with stock intakes that is for sure...

Here is a recent test of a stock LS3 intake vs Mid Rise. The mid rise doesn't fare well at all in most situations. Boost tends to favor long runners as well.
Flow goes out the window when it comes to boost. Flow characteristics take over.
I have a dyno sheet somewhere of an LS6, TBSS, and Mid Rise all back to back. The LS6 made 10 ft lbs more up to like 6400 RPM and then 6 HP less up top for 200 RPM or so. The TBSS made more power/torque than the Mid Rise from start to finish.

also I'm using the holley mid ram efi, not the sniper low profile one. i know the sniper intake is junk and its only a show piece. its sheet metal and it doesn't hold the boost pressure. is the mid ram the same junk and the sniper ?

Well that certainly is commitment to an idea.
I have made really good and trouble-free power with the Mid-Rise on our Procharged LS2. I went through the bother of extensively porting it as it was pretty rough out of the box. I, like you, wasn't worried about every single digit on a dyno and chose it mostly for its looks (and construction).
But, yeah it definitely doesn't fit a 4th Gen.

I have the high ram on my 2012 camaro and everyone said dont do it cause it gives up so much torque but i wanted that look so i bought it. Maybe im stupid but it looks awesome. I wanted to see how.much of a difference it made in feel of the car so i swapped back and forth from the high ram to the ls3 intake 3 times and never felt the difference under boost. Did it make more power on the dyno with the high ram. yes marginally and it made more torque and the same hp to 5400rpm with the ls3 intake but with either intake off the dyno i never felt it one way or the other. Not an apples to apples comparison just my opinion. No disrespect to anyones views here. Just throwing out my experience.
