Really? I figured it would help alittle and atleast improve mpg while i was cruising .I know the head is pretty bad. The shop I use doesn't have anytime to do what I want atm and taxes still haven't come back so I can get my rev valves, springs and forged internals

I love when people say our heads are "bad"...cause making 450whp out of a 2.4L 4 banger with a T05 hot side and a 44-47lb wheel upgrade is soooooo terrible.

Are there better stock heads out there? Obviously....but we all drive 8-10 year old $19k Dodge Neon. Come on people.

What I meant to say the flow design is bad. But yes for 430 HP with just a turbo and basic stuff is damn good. there is always improvements on flow you can do to our heads to breath easier and increase power and make it more efficient. With no other options that i know of to bolt a head on that has better properties . We are limmitted to either stay stock or go bigger and better as a way to increase power. To say its a bad part is not right. I should have worded it diffently.

Damn that's pretty impressive power for a 4Xlb turbo. Did you ever get a dyno graph?

I'm a believer in a bigger TB. Don't you remember back in the day when I did a before and after dyno on my car with a 55mm Tb and ported itm. Only mods on my car were an aem cai and mopar rice plate. I picked up 12hp and 20tq peak but like 30hp in the powerband.

I say try the TB out. See if the guy will let you do a before and after.
Don't forget to port match the opening of the itm to 62mm.

our heads do suck man. We are just lucky we have a big 4banger.

I can do this same upgrade for anyone with a stage 3 kit.

yea stock head blows...car easily picks up 40-50 whp on same boost with a nice head. Also makes torque sooner resulting in a nastier powerband. Head work is night and day and worth it's weight in gold. You can keep your torque down (maybe save your motor) and bring the WHP up...faster car that's stressed less

You want to see nice heads from a factory...stroll over to Honda (even from the 90s they had better heads than our cars today..a stock k20 on the flowbench might look like our Pro Mod DCR head )

I don't recall you picking up 12. Maybe I didn't hear it correctly, or maybe I'm just old, I recall not being impressed with the results and I would of been impressed with 12whp. I'm not doubting your claim, I'm just going off of a 6/7 year old memory.

If it were important we could ask Brandon or Jose, but It's not important to me.

So triangles, II stand corrected. Go for the new TB! After all it's your dime. I personally would put that money towards getting the head ported.

Reason it makes 450 whp is because you crammed everything in....look at the torque once you start going up in boost on most stock head cars. Trend is it makes crap loads of torque at first; head chokes it off and you squeeze by 450-480 whp while making 500+ wtq. Stock head cars drop torque off like a rock after 6k. I lose about 50-60 wtq by the time I hit 7k; before head work that number was more like 100 wtq. You can look at any big turbo dyno and see similar trend all over the place (unless they have super big laggy turbo). Any car can spike torque down low...an efficient motor will HOLD that torque; which our car does NOT do very well

Not unusual to see 500 wtq at 4k rpms and by the time you hit 6200 you're making like 380 wtq..

Enginejoe had the typical high 400 whp stock head SRT...look at that torque at redline..

No free lunch my friend.

I was hoping it was the gain feature in the boost box
