There is no chance of putting down 330-360rwhp with those mods. a 96-98 2v with a pi swap and bump in compression ( pi swapped 96-98 makes more than a 99-04) you would maybe see 300-310rwhp.

 

Purp speaks the truth...

 

I think that too often, one guy is talking about flywheel hp and another is talking about rwhp. This causes a great deal of confusion.

350rwhp on a 2V NA car is pretty darn tough to achieve in anything that would be streetable. 350 flywheel hp is quite possible with cams, heads, exhaust.

Lets just wait and see what the dyno sheet says when he gets the car back from his mechanic.

 

I wish people would stop trying to rate fylwheel horsepower when they talk about their ride, the only way to get your flywheel horsepower is to have the engine on an engine dyno, and 99.9% of the people out there never have that done.

 

Talking about flywheel horsepower is like telling a chick how big your johnson is after you measure from the bottom of your *****. Just don't do it, you set yourself up for disappointment.

 

I agree that flywheel hp is a pretty useless figure. Using it only serves to try to inflate the number to make it sound better. It would be nice if the factories would begin using rwhp to rate their vehicles, but I don't see that happening.

Also agree that very few guys have actually had their motor on a dyno. Therefore, guys are taking the rwhp they got from dyno pulls and inflating them by calculation to come up with a projected flywheel number. Kind of senseless.

I'm anxious to find out what OP gets for rwhp when dyno'd. The comment about "pistons bored 20mm" still has me wondering if he has more than a basic heads,cams set-up there (ie. bored/stroked).

 

Unfortuantly many big name tuners and engine builders have proved that there is very little benefit from stroker based 4.6l

 

Yup, I have seen several stroker 4.6 motors make disappointing power numbers. The torque is better though. Torque is what accelerates the car, so just looking at peak dyno HP numbers doesn't tell the whole story. Area under the curves are the goal.

I kind of doubt that OP has a stroked set-up, but the remark about 20mm still has me trying to figure out what he actually has. Maybe we will learn more on Monday.

 

I miss my old 2V Bucket

 

FWIW, the most ive seen out of an NA 2V 4.6 motor is around 410rwhp, and thats out of a 5.3 stroker, TFS heads, intake (either edelbrock or something) and BIG cams...
