Interesting observation about turbo builds

I'd like to understand the engine and why people are going conservative instead of going with a much more aggressive setup. There has got to be a reason other than "lets not blow this motor into crap".
The SR i used in comparison didn't even have a lot of advanced timing. It was up to 18degree's. That's LOW for a blacktop.

There are several that do excellent with boost... Again different engines respond to boost differently. But that has to do with turbo efficiency and all in all it has to do with the tuner. The tuner can make or break your expectations (or parts lol)
So I've been contemplating going boost since the inception of buying my sedan especially since I've tuned and built many turbo builds...
But after seeing the numbers of many buds here and generally online.. im not impressed.
On a recent thread a individual made 517 @ 17psi using 93 octane and a full stand alone.
On a 93 SE-R sr20de-t we made 483 @ 18 psi using 93 octane tuning with a safc. Turbo was a 57trim with a .48 turbine. It's an entry level T3.
The math just doesn't add up....
517 / 6 cylinders = 86 hp per cylinder
483 / 4 cylinders = 121 hp per cylinder.
Either these setups on the vq's are really conservative or the engines just don't like boost and are inefficient.
Tuners how much timing are you guys pushing?
Oh ps the Sr20 was OEM not built either. We ultimately made 502 whp with the aide of a 50shot.

i'm not trying to **** you off, i just think you're looking too far into it. sorry, if i came off like a d!ck. honestly there are so many variables between different engines and HP per Ltr, there's no real comparison there. the real question is why do boosted VQ's only make xHP? there are a lot of reasons for that, mostly cost. not just initial cost but in replacement parts too. so to keep cost down people end up not maxing there engines out. build everything to handle 900hp but only make 500hp and you get a lot more piece of mind for the money.

(Bad example but you get the picture)
Ps, you're not pissing me off. If anything you gave this thread some life
... Just TUNERS need to step in and give some details as to why who what where etc...
IMHO, that's like having a ***** enlargement and then jerking off instead of pleasing a woman with it..

you should try to run the max boost you can squeeze out of your preferred turbo and report back.
with respect to timing, there's a thread on my350z.com where a member requested people post up how much timing they were running at a given rpm/boost/load. might be of help to you.

I also look at torque when comparing numbers and I bet the VQ puts the SR to shame in that department, but it does sound like the VQ you are looking at was on the low end of things
