hey i just got a half bridge put onto my s5 TII and want to know is it safe to run on the stock setup i do have a fcon and super AFR do i need bigger injectors? i do have the walbro pump also thanks Corbit

 

are u gonan run this on a stock ecu? i woudl recommend you get a haltech or a microtech. the stock computer is realyl nto meant to run what you have in there.

 

The stock computer most likely will not run it anyways. When go BP you need to upgrade everything...

 

ya i am going to try and run it on the stock ecu with my piggybacks. The guy who did my bridge is running his on the stock ecu but his is n/a

 

its kinda of a big diffrence runnign a bridge NA on teh stock ecu then a turbo. i assume you are not useing the stock turbo on you rbridge turbo?

 

Would'nt that bridge snap under all the pressure put out by the turbo?? You rarely see bp turbo setups because of them supposedly snapping. I heard it somewhere.



Correct me if wrong.

 

No! Half bridge motors are quite reliable in turbo form if done correctly and the same requirements also apply to the N\A.

 

They run fine, Rowearth. I've been doing these setups for just over a year now and have almost 15 of them out and about. The trick is to leave the seal bridge thick enough to withstand both seal spring pressure and heat cycling.



I don't think there's any way in the world a half-BP engine will run with the stock ECU. None whatsoever. I set my vehicles up using Haltech EFI systems and they take quite a bit of trickery and map changing to get them even in the ballpark.

sorry to hyjack this thread but ......so u can run your stock computer if u have a bridged n/a or ported in any way n/a?

 

Why spend all that money a BP motor and use the stock ecu and blow it up? You will need to get a aftermarket ecu, then get it tuned. There is also no point of running a stock or small turbo with a BP, you will only overboost the capabilities of the turbo. Don't forget fuel, stock will not be go enough.



Do it right the first time!!!
