Depends on mods and tune. My cam will live the intake and heads

Im sure all mentioned above would be fine but you'll pay a premium price w/ Mamo.

The track is a funny thing. Sometimes you can make a change to give you more power but if you can't apply it then it does next to nothing.

Typically a 10-20 hp change could net you over a tenth depending on how fast your car is already and assuming they are similar days with a decent pass.

Now for me I've made quite a few changes since the first time i went 11.1@124.x with a ls6 intake to basically only net me a .2 gain in the end. But the car has picked up a solid 5-6mph in trap speed with only a 18hp at peak gain. Under the curve is where it's at. It's probably picked up over 30wtq in places. The 124 was on a 10bolt to now i have a 9". Best mph was on a 10bolt @ 131.3. Best on the 9" is 130.6. So sometimes there is some give and take......but I'm not fixing a broke 10bolt.

20hp or 20whp?

Aren't they one in the same?

There's like maybe a 2-3 hp difference when comparing 20 rwhp to fwhp

I want an intake that gains nothing at the flywheel and 20 at the tires

I highly doubt its that much....if any. It's only gonna take so much to turn your drivetrain.

For what it's worth the cathedral MSD is the most challenging composite intake to port properly and I remove about 30% more plastic than you will see documented in this thread I included in a link below. Without the removal of significant amounts of material in the tighter cross sectional areas of this intake it's really a very poor design out of the box....in fact it takes me more time to port a cathedral MSD than any other composite intake manifold I have ever worked on, but handled properly yields good results in the upper RPM region of your engine's power curve. Most shops havent done alot of these I assure you and you really have to know what your doing (aka be more of an expert in the art of airflow and design cylinder heads and manifolds for a living) if you're going to get the most out of that particular manifold.

This is a good read for anyone considering port work on an MSD (or a FAST for that matter)

While it hits mainly on my work revolving around the MSD LS7 unit, the points made in the information below are all still applicable to other manifolds as well

A "ported intake" all sounds the same on paper no matter who puts a grinder to it but in the real world the difference in performance can and will be quite dramatic considering the varying level of background and experience the guy wielding the grinder brings to the table.

You get what you pay for in life.....the guys that make the most power on this board (and others) have already figured that out.

If you get it ported by Mamo then you need to go with the ultimate combo.

Channel that Mamo power through a Momo steering wheel. It's a win/win.

I値l sell you my momo parking brake handle lol. I forgot that guy put that stuff in my car.

If the stock cam looks good when I pull it then I知 gonna do a cam only setup but if it looks beat up then I値l need some lifters so I値l go ahead and throw the trick flow heads on. No reason to put the stickers back on. I知 still trying to go faster than that 11.24 that I ran before I go from just bolt ons. I wanna stay in rumble so I値l have to run 11.00 and slower. Heads/cam maybe too much to slow down for that. I gotta tear it down soon if I知 gonna do it cause April may be the first race in the series this year.

You may just have to go aftermarket heads/cam/intake on the daily driver then.

I too have Ling ported 243 heads with a FAST 90/90 making right at 450 with that setup.

What trans and rear? I wonder how much the hp is reduced on a dyno when a 4000 stall and Strange S60 or 9" rear is used? 30-40hp?

I know my buddy lost 30 hp going from a 10 bolt to a 9" and a 3.73 gear to a 4.30. Same dyno within a few weeks apart

That's interesting...

Yep and what's even more interesting is that he traps 1-2 mph better with more weight and 30 less hp. I think the gearing helped a lot considering he has a 4l80

I have a vrx-5 and and full exhaust. Cnc ported heads and soon a ported fast 92 intake. Few stuff to finish off. I'm hoping I'll break 450whp
