What is the easiest was to get 320 rwhs? I prefer bolt ones (ecause of the $$), but if there is other cheaper way let me know.
Thanks
ps. Cai+good catback+good headers= ???? rwhp?

 

I would say that a K&N FIPK, a cutout or good catback, and some longtubes would get you in the 285-295 rwhp range............................i have those same mods and thats about where i should be. Dont be intimidated by the LS1's big dyno #'s. My 290 rwhp car is about the same as my brothers 315 rwhp LS1. Thats just how it is for some reason. And i know my brother is going to comment on this one so go ahead bro.

how can u get 10-20 hp out of headers,catback and cai?
the stock is 275

 

Are you totally against using nitrous? Because just a little 100 shot would put you well over 320rwhp.

CAI, LTs, Y, catback should put you around 290-300rwhp. Add an electric WP, a 52mm TB, and a nice set of RRs (even though I don't consider them a bolt-on), that might put you around 310-320rwhp, maybe a little more.

You can get close to 320rwhp with just bolt-ons and possibly surpass it but it definitely won't be a given.

Do most of the bolt-ons (at least the significant ones) + a hotcam (or equivalent/ or bigger) and tuning and you'll easily hit 330rwhp and probably get closer to 350rwhp.


This is all assuming that you're talking about an M6. If it's an A4, subtract about 20-25rwhp. IOW, 320rwhp with a bolt-on A4 is pretty much impossible.


Oh, and since we're talking about just dyno numbers, a lot depends on the dyno. You may make 320rwhp on one dyno and make 300rwhp on another, track times are the only real indication of how much power a car is making (with a good driver of course).

 

We're talking about RWhp, not FWhp. The 275, 285 hp ratings were fwhp.

 

long tubes, catback, rockers, cai, tuning.
close enough

 

I know this post is old, but if you want too make 320 + rwhp and 340 + rwtq. Here is the formula to make the number in my sig. I still have not done any pcm tune or run the cutout open on the dyno. I would like to think that those two mods will probably put the car @ 340 rwhp & 355 rwtq. If so I may have the meanest non-modified internal stock heads and cam LT-1 that I have seen??

 

you gained 105 fly wheel hp with ram air, 52mmtb, electric water pump, roller rockers and long tubes?

and now your losing more power with 12 bolt
so around 115hp witht he above?
the rest your mods wont give you more power.

and aren't both FLP and B&B triflows headrs?

 

B&B Tri-Flo's short for the exhaust system. Yes the car did make that number on a couple of different occasions. Two different dyno's. I'm pretty confident it is a freak!!! I have run many LS1 that cried foul and found out otherwise and yes I do have respect for the LS1 there are many out there that can make me humble! I did pickup quite abit from the MSD digital 6 which surprised me. I would not normally call a DIGITAL 6 a mod, but it was in my case.


Oh yeah the car is 305 flywheel rated in 1996 WS6. I think it dyno'ed 278 stock. I can't remember it has been a long time ago. It had a k&N filter and that was the only mod when I hit 278 rwhp.
