Default Can i break 500rwhp with this setup?

This is going into my 300zx.. Called a dyno guy a few towns over and he said I wouldn't be anywhere close to 500rwhp.

Lq4 strokes to 408ci with a eagle competition rotating assembly
Fast 102 w/60lbrs
102tb obv
Texas speed giant cam 248/256 .615/.615
Advanced Induction 226cc heads (should put me around 10.8:1 compression with dual springs rated .660)
Truinion rockers upgrade
Morel 5290's
Ls2 chain
C6 balancer
C6 Waterpump
Kooks mendrel bent custome made longtubes 3" collectors 1.875id piping to a full 3 inch exhaust with (No resonators or cats) full through.

I was hoping for 500.. but his comment over the phone really upset me and I was almost in disbelief.

Also, should I run a maf or SD? last part of the puzzle for this swap.

Lol I think it will be pretty close. The heads are the only limiting factor. But I made 500 with a 403" and patriot stage III heads and a fast 92.

I've looked up a lot of other 408 builds and I don't see at all making such a low number on a healthy motor with the bolt ons I have.

I think you should be right at it give or take a few either way.

Or maybe he has a stingy dyno and knows it well?

Looks like a good setup to make what you want or a touch over IMO. But it's just a number...

Yeah yeah yeah just a number. Your one of those guys aren't you. You can have a high number and great driveability and powerband.

You're right... I'm "one of those guys" who has witnessed a car make a variance of ~60rwhp between 2 different dynos. I know of a dyno I could put my car on and "lose" ~30rwhp from an already conservative number.

My point was either the guy misunderstood you or maybe he knows something about his dyno that you don't.

Or at the end of the day he could simply be ignorant to what builds like yours should be capable of.

Never did I say or even imply anything about the manners or powerband of your vehicle.

Well I guess it's a shame he is gonna lose business just because he won't **** in your pocket.

Pretty messed up view if you won't take your car to someone simply because they are honest with you...

Nah it's just I know my setup can make more power. if he can't squeeze it out why go to him when there other good shops in the state. I just feel like he doesn't really know what he's doing if he thinks I won't go anywhere near 5wheel. when many h/c/ 408's have no problem.. Plus he was a dick on th phone. Really. My last car was TT z32, and I I brought it to this other shop called pro edge tuning and they did a great job. I was just looking around at other options which was why I hollered at him.

All dynos are different and also transmission, clutch, torque converter, rear end all makes a difference as well.

Should be close to 500 HP....but you gonna give up a bit with that 10.8:1 compression ratio. Kinda low for that setup.

BTW.....go to another tuner. The 'message/ I got from the guy you called is that he's unable to tune a build of your type.

Should easily surpass the 500 rwhp mark with a DynoJet.

Frankly, it looks like you are kinda impatient and a bit of a know it all with not as much knowledge to back it up as you like to think. Did you even ask him about his dyno? If it's a Mustang, you won't hit 500. If it's stingy, you may still not. What makes you so knowledgeable as to know more than someone who does it for a living? I can see your point about him being a dick on the phone so take your money elsewhere. All things being equal, on a dynojet, you should be right there...assuming your car is well tuned and there are no other issues. Regardless of all that, this guy's approach is suspect, his reputation isn't sterling, and his verbiage and attitude wouldn't make me unass cash in his shop. If your first impression isn't good, why spend thousands of bucks with him?

Impatient yeah. Know it all... Ehh. it was a mustang dyno I made sure to ask. I'm bringing my car to slowhawk in Massachusetts. Don seems extremely experienced with lsx based motors. And he was super cool and optimistic about my build.

Knowledge AND enthusiasm......a couple of qualities that I'd want from anyone working with me on my builds!
