Stock MC1 2226cc 5cyl 10 valve engine, K26 turbo, 346cc injectors (S4), homemade fuelrail, Ford FPR, Ford tps, MC2 intercooler, 3" downpipe thru fake-cat til rear axle then 2,5" with single rear muffler, Bosch bypass valve (plastic from SAAB), camshaft from 2,2 -86 non-turbo, modified stock aircleanerbox with K&N replacement filter, open crankcase vent.
It now runs with 1bar boost because the Ford FPR doesnÂ´t allow me to increase the fuel pressure over 4,2 bar@ 100kPa...if i do so the regulator blocks in boost and pressure rises above control.
I am surprised that most 5000 i see here uses stock exhaust manifold, i am ready to throw mine in the thrashbin!! Does it really work well in high boost??? Thats the reason i signed in here.....to get some ideÃ¡s and pictures from the big guys "over there" about manifolds....well well
Best regards (and excuse my school-english) Micke in Sweden
My new injectors and the incoming new turbo will hopefully give me around 300-350 hp........i hope ;) (maximum)
But the boost increases with rpm so it requires a control pressure in the upper chamber of the wg valve. IÂ´m running on E85 now and the injectors have a tough job, high dutycycle but also very rich mixture, when i checked it with wb O2 sensor it read 0.69-0.71 lambda in all boost areas....that is now fixed properly (almost). My crankcase ventilation needed a little fix because my cylinders are a bit worn, welded a cathtank with an aircleaner on top and it works well, if the crankcase pumps out oil it will flow down again....sweet i have now put my mods on the car aside because summer is closing in and my daycruiserboat with Chev 350 Mercruiser takes a lot of time in restoration.....hopefylly it will hit the water in 3 weeks, over and out from Sweden.
Now itÂ´s equipped with an S4 intercooler, new bigger pipes from turbo via ic to the intake manifold, S4 seats which hopefully will make my body stay on the right side of the car at the icetrack in the winter
The "new" ic from Audi S4, slightly modified
Tighter front engine mount, and much more space behind the plastic bumper
And the really nice front seats......
wish more people would post pics up with their threads.
