Your car sounds really good man. Whats your power goal?

[@335iN54Enthusiast]

Thanks. I'm not sure yet lol. For now I just want to max out the stage 3 lpfp probably around 650whp...

[@jacoblami1731]

@@335iN54Enthusiast You can get more than that on your LPFP running high octane race gas or E85 (probably harder on the pump). Either way LPFP is a weird bottleneck since it's so easy to replace on our cars. One of those things you just flip up the back seat and can upgrade in less than an hour or two once there's just not enough fuel pressure to keep up with your maximum safe boost pressures.

[@daviddeleon6368]

They have stage 2+ fuel pumps that support 650-700hp if you don’t want to wire up a hob switch, bc the stage 2+ is still 1 pump unlike the stage 3 were you have 2 pumps

[@335iN54Enthusiast]

Hmm I actually have a stage 3 pump lol I forgot.... Perhaps I wired mine to always run both pumps but I need to reassess the situation I think lol....I'll look into that though. I should be at the 650 wheel mark.

[@dolphinfan1493]

If you want 2 fuel pumps to run off the DME get the BMP4 it’s great. Replaced ekmp3

I don't know if it's the wind but it sounds very Stuttering like its misfiring but no engine management light...can you hear that in person? Or is it just the microphone? Sounds like it only running on 5 Cylinders.

[@335iN54Enthusiast]

What you're hearing is my wastegate regulating the boost out the open dump tube...sounds like a fluttering.

[@jumpmanadam1536]

@@335iN54Enthusiast mine does that as well

[@TheFasterBiker]

Are there any drive train weaknesses I should know about when running Drag Radials on these car's ??

[@335iN54Enthusiast]

Not really. I haven't had any issues. It's possible to snap an axle...hasn't happened to me yet.

[@CptMinnesota]

Is there a way to eliminate that flutter from wastegate?

[@335iN54Enthusiast]

Yes don't use an open dump pipe.
