Erik, what kind of turbo do you have on that thing?

Walbro 255
750cc secondaries
R-Tek 1.7 chip
stock turbo/TID running 13psi via Profec-B

I'm hoping for around 230whp.

i thought this setup would run closer to 300 to the wheels???
with stock ports????

SonicRaT 02-14-06 01:55 PM

With a stock turbo at 13psi, it wont be over 300.

88rxn/a 02-14-06 02:17 PM

but 300 is possible???
you told him 260??
ill prob. invest in EGT and i would like to be at the 300 mark...
with a 1.7 and safc is it possible with 2 1/2 DP and 3 inch exhaust???
would it help if i went 3 inch DP??
all on a 6port

SonicRaT 02-14-06 02:53 PM

The stock turbo doesn't move enough air, it'll run out of steam around 275-280.

Jager 02-14-06 03:04 PM

Only one person has a dyno sheet?

SonicRaT 02-14-06 03:14 PM

Probably, the availability and cost of dyno time doesn't exactly make them very common.

i see... after i get this setup done i thought about a stage turbo from BNR... would a stage 3 be to much??? how about 2... im not looking for much more than 300... and will my 720's support it??

SonicRaT 02-14-06 03:32 PM

support 300rwhp? No, I wouldn't try that, they'll be damn near their limits.

A stage 1 will just reach the 300mark on low comp. So no prob on a higher comp setup.

88rxn/a 02-14-06 05:38 PM

thanks guys... what injectors should i get for secondaries??? will the 550 be enough for primaries???
iceblue: im sorry for hijacking... im done after this question....

iceblue 02-14-06 06:03 PM

I would run 850's :-/ and 550P

jacobcartmill 02-14-06 06:44 PM

i'd say get some 1680 secondaries. they're cheap.

id like to but id never be able to control them with a SAFC II and a rtek 1.7

jacobcartmill 02-14-06 10:07 PM

oh! sorry i didnt notice that you were on the rtek7 :x

I've just got a stock turbo on it right now... :D

I don't put a lot of emphasis on the higher-compression rotors. I think they're a little bit over-hyped. The throttle response etc. might be a little better, but I'd honestly rather build with 8:5's just to keep it safe...

I also doubt that I'm gonna hit 260 to the wheels. The 2.5" DP/MP combo and the stock TID are pretty restrictive. We shall see though... ;)

You could... Just tune it correctly. :) Forget about the R-tek as a means to control the fuel, just use it for the timing retard and boost-cut prevention. Throw the big injectors in there and tune them down. ??

yeah these are my plans... the rtek is really for what you said but to big of injectors and ill have trouble... im having small trouble now with 720 and stock ecu but i havnt no one to drive while i tune.. as soon as the weather gets nice and my exhaust leaks are fixed im gonna tune it better... im in the 10.5 to 10.9 range now just for saftey... well...maybe its my damn TPS giving me trouble.... ugh....ill prob. go with 850 or whatever is close to 720's cause i still have a n/a drivetrain with a centerforce clutch and the clutch wont take much more than 300 so ill keep the 300 mark realistic....for now :)

eriksseven 02-16-06 01:33 AM

I'm not dyno'ing my N/A setup until the 26th of February. I thought it was *this* Sunday on the 19th, but the date was changed. :)

JoshRX7 02-23-06 06:16 AM

Don't blow her up Erik :) Step away from the boost controller! The old TII is still running. Same ole same ole.

Josh

88rxn/a 02-23-06 12:34 PM

almost D-day for eric !! post those #'s !!

SonicRaT 02-23-06 04:36 PM

Blow it up! Maybe if ya do it'll deter people from wanting to do this swap and PMing me 500 times a day! :p

JoshRX7 02-23-06 04:58 PM

hahaha... word. I wish no misfortune on Erik though, he's a pretty good guy.

Josh

SonicRaT 02-24-06 01:03 AM

Yeah, true that, but it might help eliminate the need to clear my PM box on a daily basis!
