anyone know of a dyno sheet around with a tvs and ported head i can see?

ralliartist

I only know of one, and he made over 400whp and something like 380ft/lbs. But there were some people that criticized him so he deleted all pics and info.

NOTE: His motor didn't last very long either. He was NOT on e85 either.

I will very soon. Just waiting for the right time to buy the TVS. I already have the head. There will be before and after dyno sheets.

ralliartist

What's your flow numbers on your head rockSTAR? also, did you use oversized valves?

Deathscythe

I have a tvs and a ported head. Look for my header testing thread, and you will find the numbers that I put down on the ported head and tvs setup with three different headers. The tune was somewhat conservative, so there was much more on the table.

The flow numbers for my head are posted on m2race.com. They did the porting.

Here is a dyno of a member with a tvs without the ported head as it is still sitting in his closet. He just got it dynoed last sat with me. A 380whp srt4 beat him by a fender right after the dyno run.

He is on 79's, E85, return style, full exhaust.

As a tuning reference my car put down put down 250/223 with intake, CA header, 3"dp, stock catback, stg2 w/20 deg timing no other tuning, 2.8, and no cooling mods.

i am in the process of building this. If you wait i can tell you what it puts down

i've got the same... tvs should be here next week and already have the prepped head sitting in the garage. was just sort of curious what kind of gains it would have over the oem head

really looking for some gas numbers, no e85 within 2 hours of my house and don't want to keep a barrel of it sitting in the garage

Darkmanx

those dynos look familiar. and self i made 10 more horsepower on e than i did with pump gas.

and ur on stock pulley r u not? and stock cams

that dynograph is not right

Deathscythe

The pulley size was 2.95. You can say I was running on 3 cylinders (no.2 was giving out on me when the last dyno was done). Look for the header testing thread I made last year. It has the dyno sheets in there as well.

And yes, it was on the stock cams.

Rally, there are a few of us with TVS/Ported head. I also have E85. No dyno's tho.

Good stuff guys! I'm debating about doing the ported head and I really wanna see some before/after numbers specifically with the TVS even though I know only a few people have done it. If I do it, it'll be a ways off though (fall/winter). 42whp is no joke though, that's f'ing awesome.

stonny9

A ported head gains alot. Darkmanx(since parted out) gained something like 50fwhp when adding a ported head and no further tuning.

when i saw "anyone with TVS and ported head?" i knew youd pop up in here at some point tom lol

That's absurd

ralliartist

imagine a set of decent blower cams to take advantage of that newfound air flow.

i hand ported the exhaust side of my head... but my flow was held way back by my tiny exhaust... but its being remedied as we speak so we will see what kind of numbers the car puts down

Area47

above 370whp, you're gasping for everything left in the blower. you have to fight tooth and nail on stock cams to hit 380

Deathscythe

When looking at flowcharts, you can see that making 50 extra whp from the added airflow isn't possible. A more modest number to have would be between 15 and 25, depending on the agressiveness of the port on both sides.
