We should see how high we can shoot on N/A without losing most of the streetability.

Thus, I propose a challenge.

The only restrictions are that the engine must use 2 x 654 cc rotors, and porting may not exceed pass the limits of streetporting. Anything else, engine or accessory-wise is fair game.

I'll start the benchmark with a low number, my S5 NA block at 170 whp, stock porting, stock manifolds, Rtek 2.0, K&N Drop-In Filter and Racing Beat Collected Full Exhuast.

 

^^^^^ I definitely wouldn't call that low considering the mods ^^^^^

What car is it in?

I like this idea...

 

Why only two 654CC injectors?

And if its going to be legit, lets make sure people actually post dyno sheets instead of just saying what they have?

 

not injectors..........rotors.......2 x 654 cc = 13B, right?

That's the motor in my GTUs, it's going to be detuned for STS2 autox next year.

 

sounds like a very good challenge. i think i'll actually throw my hat in the ring for this one.

by the way, i'm REALLY glad they created this section.

 

Yea I'm in the process of a build that I'm still gathering all the goodies for. Wont be ready until after the new year but challenges is a great motivational factor for me!

 

I will be getting started on mines very soon. I still need the side seals, but i have everything else. Im having a hard time trying to figure out how to put the pictures from my computer to this website. I Would appreciate anyones help on what to do, Thanks!!!

he's just above 170whp with his 13b and 140ft-lb of torque and i believe that is stock port.

Richrotorhead is at 181.50hp / 134.20 also with a 13b (street)

weedwacker is at 157.68hp / 105.00 with a 12a (Street)

ZIIG is at 152.10hp / 100.00 with also another 12a (street)

rx7- smurf po is at 142.5/ 124.2 with a 13b (Stock)

Max7 is at 131.60 / 117.20 with a 13b (stock)

RXtuner is at 149 / 115 with a 13b (street)

We should have a little list in the top of this that would keep on getting updated to see who is where.

I'm currently at 147.30 / 124.20 with my 12a streetported and should be getting close to 160/170 with probably over 130ft'lb of torque with my ITB's.

That should get things started in the right foot.

 

DREYCO is at 165rwhp

s4 ecu on a safc with an s5 engine

open intake open exhaust
wired vdi and no 5/6 port sleeves
no emmissions
and thats it,
110k on engine

I should be around there possibly. I have the same setup basically except working VDI and AUX and I have a CAI I built for pressure. 115PSI compression on all faces.

Wow, good numbers for a 12A. You ever think about swapping a 13B in for more ponnies?

 

Does anyone knows how to transfer pics from computer to here

 

click Post Reply, there's an attachment section on the page afterwards

 

It keeps saying upload failed.... is there another way

 

make sure you meet the right requirements of the pictures. You might need to resize them.

Rotaman99 - No I do not have any plans. I'm keeping it 12a to stay different. Its nice to go to a meet and just be a tad different while making good ponies.

 

Kahren did 195 a couple years ago: https://www.rx7club.com/time-slips-dyno-128/na-6port-streetport-dynoed-195whp-update-418805/

 

Logan from defined autoworks made 206 rwhp, 151 rwtq, with a 13b-re.

third post down, but it looks like the picture is broken now ?

 

Nice figures so far.....I'm hoping this gets people to try new things and get close to that almost unattainable 250 whp mark.....without a bridge/peri port.

My setup won't be done for at least 3 years. =(

 

Same thing i thought. If more people try, alot more things would be accomplished from theses motors. To bad alot guys on this forum scared people away from trying.

 

I think our problem is that too many people jump on the turbo boat before they do anything. I'm curious however what judge ITO's street port does on the dyno

 

Yo whoops. My reading comphrehension seemed a bit poor, but still, I think real dyno sheets should be needed.

 

206 would be a nice goal to reach for.

 

I'll hit that, RWHP, with my Bridge... Come on... let me play too! Let's have a seperate category for Bridgies!

 

Maybe not seperate just do it lets see what numbers you get from it.

 

boo.......gas mileage......

173 on stock ports and stock ECU.

I suggest a sticky thread similar to what they have in the 1st gen section. Just throw up all the NA power numbers and include a note on mods and porting.

 

loving this thread .
