I decided not to go to the dyno for a couple reasons. Most importantly, my stock turbo has really bit the dust in the past couple weeks... I should've never turned up the boost to 13-14psi on a turbo already blowing oil, lol.

The wheel is now hitting the housing at any boost above 5k RPM's and 10psi. I pulled off the TID and found a bunch of 'angled' scar-marks (same angle as the stock blades). Anyways, I've got a new turbo and 80mm DP/MP on the way and there's another dyno-day coming up, so hopefully I'll get some numbers soon.

Oh yeah, my second reason for not going was that it was my Aunts 50th BD party and I felt obligated to go.

 

She will be 50 for a whole year not like you dont have time to make it up.

 

understandable erik...she drink?? older aunts that drink can be a blast!!!

 

well i have a NA s4 stock 6 port block with about 200K miles on it, with turbo II manifolds port matched to fit the block, and rtek 1.7 ecu, safc, and stock s5 turbo with exhaust fin damage from my turbo motor blowing up.... i have 3" ehxuast and TID mod also ,

anyways i ran a 14.3 few weeks ago,

at about 8 psi( i couldnt get any more , my manifold to block exhuast gasket totally disinigrated , and created a very nasty exhaust leak, it wouldnt boost any higher no matter how much i cranked my boost controllor!! haha...) stock na clutch and 1 tire fire. couldnt get the car to launch very well at all...

fixed my leaks and i have boost set at 11 psi now and it runs much better and spools WAY better... i am also installing an LSD rear diff, ill see what she runs after this, hopeing for a 13 next time

april first i plan to dyno this monster, if it lasts that long... its got ALOT of miles its very tired....

 

when does your see full boost???

 

I'll post my results in about 1mnth if all goes well. Twin t25's on a street ported 6port with stock exhaust ports.(It's a long story) I'll post pics and all the info when I get it on the dyno. Good luck with yours. I'm running the 1.7 and safc2 as well.

Pfft, excuses!

I want to see 12s damnit!

 

turns out i was wrong..it might not be till may or june when the track opens...
sucks but they are cutting it down to 3 runs this summer...that gives me 3 days to (hopefully) hit this mark...

 

hey guys i heard that turbo 6port rotaries get 38mpg. is this true?

also, i heard this happens if you use a stock ECU and some big injectors and an SAFC.

 

Yes, it is true. And they're faster than your slow *** too! Win win cartmill!

 

I think I'm dyno'ing on Saturday... YEAHHH!!!

street-ported, RA seal'd, 9:4 rotors with 80mm exhaust, stock turbo running 12psi via a Profec-B... Woot, woot sucka's!

 

erik, how does that stock turbo hold boost at 12psi?

also, is it an s4 or s5 turbo? i'm curious to know if it holds boost til redline, and if that profec-b helps at all.

 

i have a stock s4 turbo and it does not hold boost!!
mine drops between 5,500 and 6,000...from 12LBS. to about 8LBS.
of course i think my turbo is almost petered out to....

 

sounds allllll to familiar. damn I wish it would hold boost all the way to the top. . lol I've got the ssac manifold as well and it just holds it off a little later but that's about it. Oh well

 

Yea mine droped from 12 down to around 7 at 6.7k and down to 4 past 7k. Stock S4 turbo

 

I've got a higher-mileage s4 turbo. It does hold boost pretty well and IIRC it drops to around 10psi by redline? I'll go out a little later and check and if I'm wrong I'll post the different results. I know that just switching to an 80mm Thunderfab DP/MP from a Bonez 60mm made a HUGE difference in top-end power and the turbo's ability to hold boost. I've got dual Apexi N1's in the back.

But yeah, the Profec-B does help with it's balance setting. It's much better than any of the MBC's I've used.

I'll have HP numbers and AFR's tomorrow!

 

ive got 2 1/2 inch DP and a MBC and it doesnt hold very well...plus the oil ring?? leaks and i got some smoking goin on but nothin major...
id like to get a BNR stage 1 with a recent rebuild...that should hold boost alot better than mine does now...

 

I've got a racing beat turbo back and a dawes devices mbc, 3 inch tid, ssac mani, and still can't hold boost that high. . lol Oh well, looks like it's time for a t4 set up. . haha

 

mmm... dyno.

I'll post my sheet later tonight...

 

WHAT you ****, couldnt even leave us with some teaser numbers or anything. . damn you. . lol

 

I dunno if the BNR would hold boost any more seeing that it is still a stock hotside.

 

yeah,

the hotside is the restriction and causes the boost to bleed down in the higher rpms, but BNR usually clips the stock turbine wheels to allow them to flow more air and i'd assume it HELPS with the problem but may not cure it totally.

 

we want numbers!!!

 

Hey I have my car running and starting to tune it. As soon as there is a dyno open I will be there or a track event to get a time slip. Hopefully dyno first. My car is S5 block with half bridge,S4 NA rotors. T04b 60-1 1.15a/r. SSAC tubular fd manifold and external wastegate set to 9psi. Hoping to get close 300rwhp!! might need more boost for that.

 

You ask and you shall receive........
