There is nothing wrong with meth injection on a stock car. You can just use water injection at first for cooling. If you run out of injector, meth would be a risky solution if you are running an off the shelf kit. The shurflo pumps don't last very long, and if you run out and do a hard pull things can happen. Meth injection is going to give you the benefit of running high octane fuel with out the 7 dollar a gallon price.

Opinions on muffler delete? I want to do exhaust work eventually but just want more volume for now, everything online is mixed between sounds great and drone.
-
"Golf tee mod" first
-
Sounds like shit. Golf tee mod is a good start and a PE mod muffler with dp's is better.
-
I didn't know that golf tee mod was a thing, I'll do that tonight and see how it sounds. I really just want volume for now and I'm not sure when I'll have a chance to put downpipes on.
-
Downpipes help open it up and add volume but even without them the PE mod mufflers sound way nicer than hacking the muffler off.
-
@jc43089 the n55 sounds a lot nicer than the n54 and you can correct me if you know otherwise but I believe the f32 doesn't have resonator's where the f30 does. It's the same in the e90/e92. Sedans have resonators.
-
PE Mod is removing all the stuff inside the mufflers, isn't it? I don't have that sort of equipment
-
Not exactly "removing all the stuff" but removing the perforated pipe inside the muffler and welding in a solid piece. For a couple hundred bucks you can get it done by an exhaust shop. Just please, for the love of all that is decent, don't cut the mufflers off.
-
Looks like PO already did the PE mod. And I'll take your word on the mufflers and leave them alone lol, I have lots to learn about modding this thing and advice is one of the reasons I come here.
Case and point, your first suggestion just arrived today. I'll take it for a spin tomorrow to try it out since my car cover disappeared somehow anyway, I'll need a new one to keep birds away...

Hmm, that is quite possible, now that you mention it I don't think there was any resonator.

Nice! The ZHP knob is awesome!

Put the car on a Dyno today to see how it does stock. Numbers were 240hp and 288tq.
I thought it would be a little higher but the power curve is amazing.
-
Good to get baseline #s before doing upgrades.
-
I feel good about these numbers and the graph itself looks healthy. There was an mr2 on before me and his graph was a mess, like it was missing or not getting good ignition.
Anyways, up we go
-
Upgrade & slap it on a dynojet.

Pretty good! A lot of n54 guys dyno with standard correction (std) so if you compare yours to others it may seem low since they used sae. Figure another 10whp based on a 4% difference between the two. Now on to mods!
