bnr stage 4 turbo question

so you don't think the stage 4 is capable of 400whp? i know j-rat came close at about 398 iirc, on a streetported motor. it will be a bottleneck on a FBP but it will still be capable of the same figures, just not taking full advantage of the high RPM port.

Talking about the guy I was quoting.
But yeah it's been done, IIRC guitarjunkie28(RIP) posted a graph of making over 400whp on a BNR stage 4 FC he was working on. Although that was probably on a dynojet and and probably not SAE corrected values. I also vagely recall seeing the same graph on the BNR site, but I don't see it there now.

what do you mean iflated Ben? goals can not be inflated, my goal is that, not saying i will definitely hit it on my first try, i might have to do even more to it but its still my goal and what hp range i want and will get to or go broke trying

i thinks it depends on what you wanna spend, the stage 4 will put you in that range for under a grand, or you could spend more to get the same power but spool faster for more money. and you will have room to increase power in the future but if you dont plan on going over 400 i dont see why not to run the bnr and save some money.
i just couldnt do it, my original WHP goal was about 450 then i thought well if i upgrade this, this and this then i could get 500-530 then i thought well if i did this, this and this, then i could get 550-575 now i decided screw it do this and this and lets shoot for 600-650. hopefully it stops there and i am not gonna want 800 in a year or two, lmao

just cause one person actually posts some results using one certain item does not mean that everyone is going to see those same results.
if there are numerous different people showing all mods and results then some people can say well i have this, this and this or real close setup to this guys then thats about as close to my car as i can find and he hit this mark so i can assume that is a decent figure.
but if you like only having two different people to compare stuff to then you go right on ahead!!!

i like how you try to jump into a conversation thinking you know what you are talking about when you have no clue.....
where did you see anywhere that someone was going to run 9psi on a stage 4....... yeah read it again..... now move on.... cause if you still are reading it as that then the short bus will pick you up at 7am on the corner near your house

i never said your figures were inflated, just was wondering why he thought you were inflating yours, unless he thought that somehow you were aiming for 600-650 with the hybrid, which is virtually impossible no matter how much the stock turbo was modified.
your high compression engine makes more power at the same boost level as a regular turbo 4 port will at the same boost level. i assume they were digging because you said it was only ran at 9psi(which isn't true anyways, i was seeing 15psi by 3350 RPMS! which can also be an issue because it was making a great amount of torque for a rotary engine), which is nowhere near max efficiency of the turbo.
but how many guys do you see upgrading their turbos so that they can run 9psi to have a large safety margin to get to that higher power level? quite a few actually but it wasn't your aim and i'm sensing ignorance in this thread from some people who came in and think they know what they're talking about.
it will bottleneck the FBP high CR engine but that doesn't mean it won't work, just won't take advantage of how the engine was built for a big turbo.

so is he running 9psi or 15psi? on that turbo, thats a HUGE difference!
