Ok, This may be a dumb question but I wil ask anyway. I am planning on getting an Rtek 1.7 very soon. I have the 720 secondaries as required with this setup. My question is what boost will these preset maps support fuel with? Can you run 12 psi and the proper fuel setting take place without the use of a SAFC? What would happen if you run 20 psi boost (not that I can on a stock turbo)? Maybe more importanly is what boost can 550 primary and 720 secondaries support safely?
Just trying to learn a bit here....
Thanks

that should be fine with whatever your stock intercooler and turbo could put out.. .provided you have the 720 secondaries and fuelpump...

i wondered the same...is the map and 720's setup for stock boost??

Anyone dyno the rtek 1.7 on their car? Interested in seeing what boost was used.
Still wondering if it is ok to boost higher then stock. I know the writeup states that timing is modified for ever 1psi of boost over 9psi. That to me indicates you can run it at higher levels...but how high?

with the stock turbo don't worry about it. . The 550/720 setup will safly support about 270rwhp. Some people have pushed that setup to over 300hp but the duty cycles on the injectors at that point must have been rediculous. The rtek will handle what ever you can throw at it. If you upgrade your turbo though I recomend that you upgrade to bigger secondaries and someway to tune them like a safc or something along those lines.

I have the same question, how much boost can rtek 1.7 handle? I read somewhere that the stock sensors are only good to 15 psi, after that the ecu can no longer compensate??

From the website:
" So with Rtek Stage 1.7, 720 secondaries, and a larger fuel pump, you should have a setup that can push the stock turbo to its safe limit (approximately 12 PSI)."

I think you meant this in the context of the stock turbo. But I don't want someone reading that and thinking that it will run their upgraded turbo running 20 psi on stock injectors and fuel pump. For the record, it wont. See above.

Depends what you are reffering to.. It's only a 2 bar MAP sensor so the ECU will not know you are running any boost above 1 bar. Therefor the Rtek7 1.7 cannot retard timing above 1 bar simply because it doesn't know if the MAP is above one bar..

with a bnr stage 2 walboro 720s fmic what kid of safe boost is recomended and 1/4 mile time

anyone

Thanks guys for the info...That is what I was looking for!

Dennis....re-read the post

1/4 time??? It depends on driver and car setup. Since we dont know either you can't even guess at that. Take it to the track and find out or look in the dyno section for a car with similar setup to determine a guess.

So if one were to upgrade to a streetport, bnr stage 3 or 4 turbo setup, RB exhaust, FMIC, and upgraded fuel system from the pump to the engine bay, would the rtek still be able to be used or are we talking stand alone at this point.

same upgrades I got and used it simply because of timing witch should be fine because you should have some sort of fuel adjustment device on top the the rtek as well as the bnr stage III is usually peak around 15-17 witch is right around one bar (14.5) make sure you have a wideband though so you don't run too lean.

i run 10 psi right now and havent had any problems yet ... course i dont have a wideband so i wont know for sure ... however it sounds and runs great ...

i have an safc which i plan on doing some fine tuning with, however its not needed with my current mods ..

i plan on hitting the dyno before the summer is out and fine tuning the safc to help get the best gas milage balanced with the best performance .. i have a feeling the rtek is running a rich map, but thats a good thing for most people ...
