IS200t tune
haha but now the fuel injection system could be a big jump and it could be the bigest thing that keepmus away from power.
I have faith in our 8AR, but like you said more research will need to be done and I also hope that more tuning companies emerge with new ways to reflash our ECU, so we can have them do data logging as well as live dyno tuning, that’s when we will get the full potential of the motor. As of now we are slowly making progress and I am thankful for Tony and TTI for doing the work!
Celebrating Lexus & Toyota from Around the Globe
BMW’s are underrated from the factory and sorry to say, but even the 320i with a tune still makes more than our 8AR.
If I’d choose anything it would probably be the integrated manifold. Especially if the manifold diameter is smaller. HOWEVER the integrated manifold is permenant, if tony plans on 350-400whp then the integrated manifold really ISN’T the problem.
Finally, the 320i/N20 engine has the same compression as the 328i/N20. The 320i will throw down the exact same power as the 328i because it’s the EXACT same engine. The only thing holding back the 320i is that they’re detuned by BMW as well as a smaller diameter exhaust.
Ill put it it this way, everything goes by compression in terms how aggressive the engine is, tuning aside. If the 8ARFTS wasn’t as strong’ then the engine compression would be lower more like 9.8 or 9.3. In the forced Induction world lower compression engines can handle more boost because the engine isn’t as hopped/turned up. Try to run 25 psi on a 13.1 C/R, the engine would blow instantly. Whereas a 9.3 C/R engine can easily handle 25 psi.
It just looks like I need to look into the injector size and intercooler inlet size versus the n20.
