Mod question on Z51 gains
ok.I have 2014 manual z51. I came from a challenger with a kennebell supercharger that was pushing 510 rwhp. My c7 now is close to stock maybe around 410rwhp. I’d really like to be around 470 after my mods and tune to not feel underpowered coming from challenger . Here’s my winter mods......haltech cai,katech ported t.b.,kooks 17/8 headers with high flow cats,E85 conversion. The big question is should I go ahead and bite the bullet and get an msd intake manifold?? If I can get 15 hp from this ,I can justify. I would hate to fall short after the tune and then get msd and retune. Also my tuner isn’t familiar with the msd but knows the lt1 well and e85.Is he going to need to know something special to get the gains from the msd or is it pretty much adjust his readings accordingly and all will fall in place. Thx so much for input. And I really don’t need to hear put a supercharger on it and call it done. I’ve took my time and bought my mods used and saved big money. I may have about 1700$ in everything.

i would not do the MSD manifold as I have not seen data to support the gains and have read several posts with quality issues. personally i think the intake is a waste of money, again i have not seen convincing data on any intake that show gains. Headers will gain you the most with the proper tune.
of course you could slap a supercharger on it and be done...lol

Lol.
It seems the quality issues were the earlier ones,so I’m not too worried about that.

Why don't you just steep up to a Z06? That way you can keep your powertrain warranty

With the weight difference alone the power should feel almost the same. I came out of a 600 RWHP 2015 Mustang GT with a Novi 2200 and My 2014 z51 Feels almost as fast but just way more planted to the ground.

Ok..........I’m sorry,I was asking for input not to trade up my car for a zo6.And I really feel I know what MY challengers power felt like compared to MY vette. Once again,just kinda wondering if I find a msd on the cheap if it could get me about a 15 hp gain?

I think the general consensus is that for a mild bolt-on setup the MSD intake doesn't provide any measurable improvement over a ported stock intake.
Have you checked out some of the builds over on camaro6.com?

You realize you're gonna be at about 4000 dollars or so with the mods you listed, which will get you high 400's, but for another 2 grand or so you can have a supercharger installed and make 100 hp more. No brainer to me. Also e85 isn't going to do much on a NA application, maybe 15-20hp? A basic A&A or ECS kit makes mid to upper 500 with no other mods, drives like stock and in my opinion is the best bang for your buck.

I would suggest she finds better things to do with her time then. Here you are ready to spend a grand for maybe 15 extra horsepower, yet you think that makes more sense than my previous reply. Lets see ...headers - 2,000, MSD 1,000, intake and throttle body - 1,000, e85 conversion kit - 500, tune - 500. 5 grand. And for the same amount of money you could be putting down another 100 hp. Sorry you (and your wife apparently) got so butthurt from my previous post.

Mine makes 475 at the wheels with TSP catted headers, K&N intake and flex fuel. Total cost was about $2200 for 75whp more than stock. Installed everything myself.

So ,like you I want to stay NA and not go down the blower route , 500 crank HP will be fine for me as to many of my buddies have ruin the drivability by going blower ( cant hook up unless on drag radials ) or to big of a cam …
I have been looking at EdgyVette's ported manifold , done by Cajun , , he has some results where he shows back to back dyno runs with his ported manifold against the " AFTERMARKET " …

At less than 1/3 rd the price ( $299.00 ) and the same or more HP and torque this will be my next mod

I hope your z51 has 550 rwhp or else the mustang would wreck it in a race.

z51 is stock but the name of the game with my previous car was traction. Unless I was on a prepped surface or running my drag setup tires I couldn’t do anything from lower than a 60 roll. Of course up top the mustang would eat the vette alive but I have more fun in my vette. Spinning ain’t winning ya know?

I will take a mildly modified NA motor all day long …. Just enough power to be faster than the rest but not to much that its no longer fun or reliable to drive …
