Don't forget you get to select compression ratio also. So you could probably go as high as 11:5.1 compression ratio, but you would have to run 93 octane or better gas only. So compression ratio bump plus full bolt ons I could see around 375whp.

Each point of compression is roughly worth 4% power increase (again, all else equal). Not too much in the grand scheme of things as seen in my previous post.

It's hard to go by dyno numbers since every dyno is different but from the bolt on cars I've seen I've seen anywhere from 290-320 rwhp from complete bolt ons but it seems most fall in the 290s or slightly over 300. Even with a .3 liter bump in displacement 60-80 hp from a cam is a lot especially with a low displacement engine. I mean a heads/ cam swap on a ls1 nets anywhere from 50-100 rwhp and it has a lot more displacement and that's with full bolt ons. Not saying Its not possible and im interested in the results but I just don't think it's that easy. And in the real world ricer math doesn't work as you can't add the hp of individual parts to get total hp it's all how they all work together.

And really all that's adding HP is the cams and the slight displacement as the build engine is more to allow it to take more abuse. It will probable really come down to the duration of the cams.

Great thread...I am toying with the idea as well man. I keep asking myself and my tuner "FI or build" ?? That is the question.

But more importantly for me, can the 3.7 cyclone handle the pro charger ? Meaning...bottom end blows out after a while ? Other issues ? Other breakages...I love the idea of a pro charger but am I gonna **** out my motor after 6 months ?

Maybe, but Glenn's car (very first procharged V6) is still running strong at 465rwhp.

That's 100% dependent on how its tuned and how you drive. A 400 whp cyclone could blow up on the second pull with a bad tune or if you're flooring it from 2000 rpms in 5th gear or something, and a 700 whp cyclone could last 5 years if you never go over half throttle.

Amen brother. You speak the truth. A well cared for procharged cyclone could last 200k miles. The pro charger kit isn't putting any stress on the motor under normal driving operations and not making boost until certain RPM's. There is not a load in the engine unless nailing it.

I'm currently looking around for a shop to possibly do this swap.
Considering 4.0 stroker, d1sc and nitrous. Not looking for a 5.0 if I do anything else it will be a 3.5eb swap. Have the money just need to figure it all out.

If I remember right the ring lands are in the stock location on the stroker kit pistons. You might be better off using pistons with the ring lands designed thicker if your going both supercharger and nitrous.

Haven't you seen killer 6 he has a stock block with forged internals and he's doing 600hp and 600tq plus a 200 shot of NOS he's been on it full bore for over a year now hope his car will last but check it out

Do the 3.7s only have forged rods? Is there any other forged parts stock on the 6?

You missed the point of my statement, that the tune matters more than the power you're making (to an extent). If a car is only making 400 whp but running an 18:1 AFR itll pop on the first pull you know. Lots of things to take into consideration.

Actually, he broke it just recently. I believe that he said he wasn't running the nitrous

I'll be installing the Stroker Kit soon!

I have a 2014 model and I'm going off to college soon. The Automotive major I'll be going into will eventually allow me to bring my own car in and work on it. I'm thinking about buying everything supersix has to offer like new cams, the intake manifold (which i haven't seen anyone use THAT yet, but i'll go for it), and the stroker kit, and a turbo later on down the road. If I remember, I'll let you know how it goes

Dont take this the wrong way man, but if you're having to ask that question, you have a LOT more reading and understanding to do first.

i mean, i'm just asking what would be safer. i already know a lot. i guess what i'm trying to ask is, how reliable is rebuilding my motor through supersix? if i do decide to turbo my cyclone after rebuilding it through supersix, would it be as well built as if i rebuilt it through someone else?

I am so confused and I am not trying to be one of those ME smart A$$es.

Is the goal just HP or is it that you want a non-V8 fast car? I mean it seems like it has been said but the kind of money thrown around here it could be done easier and cheaper I owuld think. Now if the idea is to get the baddest NA V6 I totally get that too. Just curious, don't get me wrong I have nothing real to add there are more knowledgeable on here than I.

I would not do a stroker kit if i was going FI, at least not turbo. For one some stroker kits the skirts can drop too low in the cylinder and may require a taller deck and sleeves that prevent rocking the piston etc.. theres some blue printing involved.

This is very true. Those forged kits plus a super/turbo charger is ALOT of money. Plus labor and a good tune? That is probably over half the cost of a 2011-2012 used 5.0 right there.

Don't know if he's still active...
But southerncyclone is doing the stroker...

I've got SSM Turbo cams and SS valves. Ported heads (not by SSM). Also have the valve springs from SSM...
Chose to get internals from MMR since SSM only offers forged pistons or the stroker kit.

By the time you build a full bolt on, stroked cyclone, you could have bought and built a decent Fox or Fbody, go-fast car and still have a nice DD Mustang.

Going for big NA power on this platform is a complete waste of resources.

That said, there is always that one person with more money than brain cells and they will do it...

and it could be awesome.

yeah sorry the first one was a stupid question. I know you can rebuild and turbo. essentially you have to. But anyhow I'll be buying the stroker kit from supersix and i'll let everyone on this post know how it goes whenever I do

I want a fast V6 that stands out from the rest, and I just want to be able to work on my own car. I want to, at a young age, know how an engine works, how to take one apart, and how to rebuild one. That's my goal with this you know? The Mustang right now technically isn't mine, so I have to wait all 3 years for the warranties to drop before the owner will let me work on it.

honestly bro i'm not sure. depends on a lot of stuff. may be a year or two. right now at home i don't have the right tools to essentially perform open heart surgery on my engine and get down to the heads and pistons and stuff. But when i go off to college i'll have all the right materials and i'll do my best to update everyone

Theres a guy on the mazdaspeedforums actually Destroking from 2.3 to 1.9 right now. Going to be a high rpm, super high flowing screamer when he's done with it lol. Should be pretty neat, but everything you mentioned is all the stuff he's having to check with right now. Changing engine geometry is a lot more daunting than these "kits" lead you to believe.
