Guys.... FBO for a BMW is actually pretty basic and fairly cheap . Whether it's a M3, 335, 550, X5 50i, etc. You can go full bolt on with any of these cars for around $2,000. It consists of intake, tune, down pipes, intercooler. That's it! This will take a 2015 M3 from 425 crank HP to 600...

It's actually the opposite. The E85 gen 3 coyote would struggle against a bolt on and tune F80 M3. They make 600 whp with just bolt ons and a tune and run 130+ mph in the 1/4..

Who makes the car cover?

That explains why I can't find it. I would like to get one. I'm not super crazy about the CS decklid.

That's pretty normal. My BMW 335 and my Cobra are all over the place while cruising. It fluctuates by at least a full point in either direction. I wouldn't worry about the values while cruising as long as the car drives normal. AFR is more important when the engine is under heavy load. I...

True. People downplay what’s really done to Their cars sometimes, but from what I’ve read these S55 engines make 600ish at the tires with just bolt ons and a tune.

I was talking about the rear tires only. That doesn’t require spacers or lugs or anything else. I will keep 265s or 275s on the front. Im running continental extreme contact. Any suggestions on something better without going to a drag radial? I think part of the issue is it’s a 275 tire on...

I thought it was BS too. Until I ran across a few FBO cars trapping 130 mph at the drags.

LOL. I knew that from the start. I haven't been on the site long, but I see a lot of your posts in other threads. Many of them make me chuckle. And I totally agree on the horrible grill on the new BMWs. I don't know what they were thinking.

A GT is a pretty good bargain for Straight line performance and a stock A10 GT will run with a stock M3. However, it takes a lot of mods for a GT to keep up with a simple bolt on M3 and it seems like all of the M3s around here are FBO. For about $2,000 a M3 becomes a 600 whp car that breaks...

:facepalm:You know what I meant. Changes the shift points. Not the gear ratios.

They gave me a new M340 last year as a loaner when they replaced one of the air bags on my 335. It had what I guess you could call a slight burble tune from the factory when the car was in sport mode only. In sport mode it kept the car in a much higher RPM range and It would burble and pop for...

I think 305s will have a huge benefit on the streets. I have a new set of tires 265 in the front and 275 in the rear on 20 inch wheels. I can't consistently put the power down in anything less than 3rd gear. 3rd gear is sometimes questionable also. Hopefully the 305s help with a bit more...

You mad or something? :angry: I just responded to your ridiculous comment that BMWs blow up at track events. I've seen no more issues with BMWs than I've seen with GT350s and Boss 302s at the track. What exactly were you fixing for them at that track? edit: No need to respond. I see that you...

You are definitely consistent!

I'm sure that could be true for some people. They are willing to pay more to be able to say I have this car or that car.

I kind of agree with that logic as I did the same with my GT. But I still wouldn't compare it to a 80k+ beemer or a 80k+ GT500. There's obviously a reason people are willing to pay those prices for those cars and not for a Mustang GT.

And where exactly have you gained your wealth of knowledge and experience on BMWs? :giggle: It's actually the exact opposite. You can beat the piss out of a N54 all day and it wont be an issue. They need cooling help like pretty much any forced induction car, but the stock block and...

I didn't see a link to buy these? Unless I skimmed too fast. lol

I'm surprised you are going back to recirculating. I think the sound of turbos spooling up and the blow off valve is addicting. I assume the ecoboost uses a map sensor which allows you to go either route?
