With full boltons you can make around 270RWHP. Then add a 125 shot of NX (rated at wheels) and you should be closing in on 400RWHP. I would avoid anything over the 125. Never heard of anyone having fuel puddling with a 125....but iv heard it more than enough times on the 150 shots. Anything overthat and your VERY lucky if it doesnt go the first time you spray it.
