What would make more power and throttle response? Just wondering what the consensus is on these two designs in respect to power and throttle response only.

all depends on setup...and turbo housing (efficiency of it anyways) etc ...i just finished my custom rear mount and had crappy response with the housing i had used on the dyno(.96)...a day later i swapped with a smaller housing (.68) for cusiousity and troubleshooting, and DAM..throttle response got 1000x better..i get full boost like 2500 rpm earlier than before..and still have great power all the way to redline..car is only in the 380's rwhp and 415rwtq on 5psi...but hey its something...feels dam good to me lol cant imagine what any of these cars with 600+rwhp feel like

my car at start up (when its "cold") doesnt spool the turbo too well obviously because of heat, but once its at normal temp. (210* or so) and ive been driving for a few minutes and the exhaust pipes are all warm, the turbo spools pretty fast...i think im going to be wrapping my exhaust in the near future due to all the positive feedback ive seen from pple that have done it and noticed less lag and faster boost...its all about combination, there are a million diff. setups out there...just remember that if something works well together and others have proved it or experienced it, it WILL work well together...whether it be front mounted or rear mounted. im sure you've heard of PUREVILS 700+rwhp rear mount turbo setup? if u havent, well now u know its possible, and im pretty sure it didnt have supra-lag lol but anyways back to the topic at hand...
and no one is bashing just giving the guy the little bit of knowledge i have with my setup

I'm sure he's used the search...
And I'm sure he would, and ultimately all of us, most value the input posted by shop owners that build turbo set-ups frequently... Of both kinds.
... Not front-mount people saying how great their turbos spool,or rear-mount people telling how their set-ups spool identical to front-mount set-ups. I'd like total unbiased posts myself... I hope respected shop owners chime in, i.e. Jose, Bob, TRT, GMR, etc.

Rear mounts suck
Obviously the less distance the exhaust has to travel to the turbo, and then the air from the turbo to the intake will greatly effect throttle response.

Yes... And while things like smaller exhaust housings and exhaust wrap help to mimic the environment a front-mount set-up produces, it ultimately doesn... Well, I'll keep my dirty biased mouth shut.

If wrapping the hot-pipes on a rear mount decreases spool time....why wouldn't it do the same for a front mount???? dur dur dur

it does...
But compare a wrapped FM to a wrapped RM now...
I like the fact that rear mounts are available... I wouldn't run one though. I gotta be lowered... Stock ride height SUCKS on an F-body... Look like damn 4 X 4's.

if there was a considerable price difference between the two types of kits I could probably be convinced to get one, but in the end they are nearly the same price.

EH, I went rear mount on mine, don't ask me why, I kind of wished I would've gone front mount but it's fun either way, now it just literally sounds like a ground jet. It really boils down to smog laws I guess, if you live in CA, the **** police will come by and jack you if you don't have a CARB #.

BuiltLT1 started this off of our other thread https://ls1tech.com/forums/forced-induction/566061-supercharger-turbo.html .... based upon our conversation where he chose to ignore my statement:
I voted for front mount... I am a rear mount supporter but you cant change the laws of physics. This still does not change the context of the original conversation. Stoleit: this is not a bash thread... it is a political spin thread from someone who cant be open minded to the performance differences of the two.
I never implied nor will anyone else that a rearmount will perform the same side by side with the same components as a front mount. Welcome to Physics 101.

The trade off is reduced overall capability of the turbo (top end).

I still love you man... I've been on your side since day 1. Once coating/wrapping my manifolds back, to get the spool workin a little better I'm sure I would never wish I had gone front mount.
