Same engine, all being equal.

Before 264whp with toda fakie

Notice at some rpm points the 15++whp.

What about midrange...specifically vtec?

blacK_Dc4

good test. so the Toda replica is not from PLM?

koczeka

Good test.
Ultra street?
What rpm the peak power happens?
Who ported the head?

blacK_Dc4

i'm guessing its the Ultra Race since its using a 90mm TB. ^^

Uncle Dave

Would be nice to see the whole graph with the RPM shown,and it is way to much engine for a replica Toda header the pipe from the last collector is only 60mm and flared out to 65mm at the final flange.

PRLSV

Ultra race.....
Midramge was much better!
Vtec was set at 5250rpms
Peak horsepower was around 9300rpms (I think)
I'll get a picture of the whole graph with rpms showing.

The head was done in a no.name machine shop around my house. They only did a 3d cut aroind the valves and neck.

PRLSV

9,950rpms is were you see the red line ends.
As you can see it maintains peak power far in the curve.
He toa fakie was indeed a plm replica

koczeka

Jumped over that, correct, thx.

Very nice powerband.

Is this a sleeved block? What is chassis it going into? Great numbers!

it seems like toda fakie works not on every motor
the other test showed it having much smoother power all across compared to other headers..

What are you trying to say here guy?

Ive never seen a B20v make those kind of numbers no matter what header is used.

even the toda number would mean 300 at the crank. which would be 150hp/ltr.

IDK, maybe that dynojet is is set rather high.

the budget header showdown graphs show toda preforming better than the other ones and having a nice smooth curve without many dips...

but it was smaller motor.

The Toda Replica made by PLM have been proven on alot of setups including 1.8Ls and 2.0Ls. On my specific setup, the PLM Toda was able to keep up with my Custom headers from 7000-8800rpm, and peaked at 255whp. I dont normally support replica headers, but for $350 ... it really is hard to beat. I had a PLM Hytech header laying around as well, but i regret not throwing it on the motor because of the dents on the bottom created from its horrible ground clearance.

You might want to search around a little more. There are guys out there that makes 280-290 on a 89mm stroke (B20v). I make 257 on 91octane and full exhaust with baby piston domes (4.2cc). The OP have the Wiseco 8.25cc. Im sure with more testing, 280whp is around the corner.

BTW O.P. That machine shop must know their doing lol ...

Usually to make the kind of power you are making, you need a real good head by guys who really know the B-series (RLZ, 4Piston, MCP, Portflow etc)

koczeka

I think U and I both suffering with an RLZ head and here is a guy achieving super result with a simple one.

blacK_Dc4

I dont have too much info on my RLZ head. I dont even have a flowchart to it....

I never really doubted the RLZ head .. I know Brad does good work , and the power I was at (257whp) .. with only 12.5:1 compression (4.2cc Piston) wasnt something to complain about.

Although, I do wonder why my Vtec was at such a late RPM (6300Rpm) vs the OP's 5250Rpm. I also noticed that whatever i threw at it ( 3 different sets of cams, 5 different headers, and 3 Intake Manifolds ) .. It never changed the power output much... (even if it made a ton of difference before Vtec). It was as if i was maxxing out at the 257whp.

As you can see, the OP just threw a header on, and it made a very big difference everywhere...

This is a 95 hatch at around 2100 pounds.

any header test (popular units of course) is good and beneficial to those who know how to interpret information.

PRLSV, thanks for the back to back test. it goes to show that even with the big tube tri-y outperforming the toda rep, the toda rep can still make sufficient power without "choking" the motor, even in the higher rpm.

DDTECH

Thanks for the test.

im currently use the plm toda replica on my b20v, i got rid of the plm tri-y based on what i read on these forums... i might see if i can find another one locally to test against my toda rep, and see if any gains can be made.

thanks for the testing.

Did you ever get tune and dyno ? I remember you doing this building

Great test ,it just shows you that your engine will pick what it likes better,every engine is different

eDm cRxXx

Both headers are great, and it surprises me a little that the big tube does not win by more way up top.w

But there is something wrong with the dyno graphs.
-Hp and Tq have a mathematical relation, and if you look closely on the graph here there is clearly something wrong. When looking at the HP-graph the big tube wins, but when looking at the Tq graph the Toda wins. This is not possible!

If it is a normal Dynojet rotating mass dyno I think it calculates the Hp from how fast the car can accelerate the mass. If so the Hp-graph is the correct one.
If it is Load dyno (eddy current) it measures Tq from how much load it can apply to the car. If so the Tq-graph is the correct one, and if so the Toda header actually wins.

Seeing that there is quite a bit more signal noise on the Tq-graph leads me to believe that the Tq-graph is the correct one, and the Hp-graph a wrongly calculated from the Torque. But I am far from sure about this. Maybe it lowers the Hp curve on the Toda over a big area because of the signal noise in the Tq.

Dyno experts please chime in

What cams are you using.

Don't get rid of the Toda copy just because of this one thread. Depending on what cams you use, the Toda can make 15+ hp in the midrange over that damn Hytech replica.

Yea, I finally got it tuned back in November (i believe), car then sat for winter.
im using "rocket m24xx" I got from DDtech. i do plan on switching the cams out in the future, if i can keep the gremlins away long enough.

I dont plan on gettin rid of the Toda rep, I said I wanted to pick up a long tube and test against what i have now.
