who has fastest bnr stg 4 1/4 mile time?
 

just seeing what im gonna be running into . i want to hit high 12s atleast . bnr stg 4 on stock port motor ra super seals front mount and rtek 1.8 720cc injecters x4 etc ...10-11 lbs i see alot of stg 1 and stg 2 1/4 mile times. the rtek is only for summer till my stand alone in september . im a moderate driver street racing for 4 years now ...

i think there is a guy who ran 11.4

wow lol

I'd bet even w/the Rtek7 1.8 on stock ports & not so big a turbo (i.e., V or H trim) 12's is totally possible w/a good clutch & tires on a cool day!!

yea i got act clutch stock flywheel tho i should run a high 12 ill be happy till then

You can run a 12 with the stock turbo, I'd aim for 11s with that turbo

I wouldnt waste 900$ plus a good factory turbo for. BNR3/4.

Did it once. regreted it. Now im moving on working on a custom mani/wg/turbo setup.

Details as to why?

Crappy-ass "tuner" + boost creep = BOOM

like i said im just looking for 12s .im scared about the rear plate cracking ive been reading up alot on this . if im going for 11s whole new set up is going in and i might as well go for 10s .

The BNR stage 4 will get you into the mid 11's. I ran a 12.1 @ 116 with 18" rims with my BNR Stage 4 at only 13lbs of boost.

If all you want is a high 12, you can do that on a stock turbo...I ran 12.9 @ 106 on a stock turbo and Rtek1.7.

I went 13 flat @ 110 with a slipping clutch with my BNR 3.5. 12's is easily doable. The BNR's don't quite make as much power as most people expect though. They're just easy to install and don't involve much if any custom work. If I had to go back and do it all over again I would have just gone gt 35r.....and popped my motor.

mines some japanese S5 hybrid. my engine was built good when I got it, even had 3mm seals and a toms racing sticker on the chpped ecu, maybe toms racing built the turbo who knows. they use to be a performance shop before they switched to just toyotas

my car dynoed 361whp 309ft-lbs with cleaned up stock ports, and a couple broken corner seals and a 2.5" downpipe @16psi knightsport chip and an AFC Neo,was running 11.8@116, now I rebuilt my engine with a med streetport and EP2a exhaust port , 3"DP it makes an extra psi now so i get 17 dropping to 15 at redline and I have megasquirt now too. I ran 11.42@121.9. its definitely faster

The secret is with the WG and the vacuum source, I have no boost controller .just an adjustable WG actuator, and I run the vacuum source to my UIM it makes the turbo alot more responsive because the wg is being controlled by the pressure in the manifold after the fmic rather than the turbo outlet

now I gave away all my secrets everyone will be going that fast FFS

Get that beast back on the dyno man, gotta update your SIG! :icon_tup: You're probably looking at very high 300's or low 400's now.

I want to beat BNR's World Record of 402whp lol
The place I go sold their dyno this winter friggen sucks, I found another one an hour and half away i gotta make it down too

im gonna dyno my shit tommarow

on the rebuild:
- what apex seals did u decide on? still 3mm?
- did you have the rotor housings resurfaced?
- what's the engine vacuum @ what RPM?

and what effect did porting do as far as what RPM when to shift gear?

thx

well i dynoed my car today . changed plugs before hand redid the timing other day make sure it was dead on ...i made 226whp on 14psi first run , then 245whp and 233 tq on 3rd run at 16psi . the dyno graph was really really smooth all the way up to 7500 . started falling off slowly at 6700 .. car was nice and cool whole time afrs were at 11-12 so im stumped i thought i was gonna be atleast at the 270whp range . no boost leaks car runs good so idk watelse to check i did reground my leading coil pack because i had to move it for the ic piping cars on a rtek 1.8

Are you sure your turbo is a bnr stage 4 ? People could make similar power on a stock turbo imo.

A stage one is suppose to be good for 300'ish hp at the wheels, stage 4 is suppose to be good up to like 400 whp.

You shouldn't be having any problems running up to 300whp if its a stage 4 if u ask me.

LOL yes im pretty sure it pretty fuckking big compared to my stock s4 . so i gotta check everything once again . motors healty didnt smoke once or gave anyweird noises or signs of something being up

COmputer? injectors? FPR? What is your setup.

Are you running a front mount ? Im not sure what stock intercooler is good up to, but i know hot intake air isnt a good thing and higher boost would cause that.

yes front mount all the good stuff

Idk my dude, you should be making way more power than that if you ask me.

What size exhaust are you running , 3" I'm guessing ?

Really have me stumped as to why the power isnt higher, 300whp should be no problem on your setup.

Was it an allwheel drive dyno? You'd probably get a lower reading on one of those.
