Lasse wankel header
 

Well since i made my first prototype steel header that made 7 hp more on my RotoTest comparing to stock log type manifold i had some problems contacting my Tig guru and header maker. He will not answering the phone, so i have decided to contact another company that shall build and weld my Renesis header. The plan is to launch the header to public in June if no more mishappens takes place! I will post data on my webpage that shall be up in a few weeks.

Great job! What other modifications accompanied the 7 HP increase? Cat elimination, ECU tuning? Thanks for your time and contributions!

Laters!

:ylsuper:

Great work! I look forward to the product. Any pictures?

he's got a muffler that will give you 10 hp too ...

Any updates on this project or your porting project?

Finally i have been talking to my "header maker"! He's back in business and shall begin constructing a small 5 series of 3 pipe stainless Renesis headers for me. When these headers is finished i don't know yet, but i keep you informed!

good news---keep us udated

Post some pics if you can.

Looking forward to seeing your header!

coolio!!

Sorry for this, i will post on Friday (i'm just screw things up today!)

yeah, i'd like to see some pics. regardless, i'd like to say good job on getting that far despite whatever people may about it.

Is there any difference in sound?

Ok! I know it,s already Saturday and no pic yet...but as soon as my friend is home to me with his camera he can upload it for me.

Yes there is a little deeper throatier tone not much but it's there!
I think when i measure the sound with a db meter 20 inch 45degree backwards the exhaust it was like 82-83dbA. That was with only the complete exhaustsystem (no header)

+1
and great job! cant wait till the pics get posted!!!

update?

I would like to see some pics

If you actually made 7 hp i would not post any pictures until you have a patent for it.Most headers now only get from 3 to 4 hp ,you never know who might be looking here and steal your design.

Pics or it didnt happen...

i want to see some proof!! i neeeeed power!!! Muahhahah

+1

those 3-4 hp ones claimed 10 - 15, get a clue ...

First i actully made on my Rototest 10-12 hp more with "my" Ferrita complete exhaust system minus header. The car went from high 6s 0-60 mph to 6.23s with exhaust system and Shell V-power 99 octane fuel and Motul oils. Then i dynoed with my steel header on same RotoTest hub unit and made +7 hp at 8000+ rpm. 0-60 mph went down to 5.86s. Of course i know this is not proof enough but when Peter G finally makes the first stainless header(hopefully in July) i will have proof with dyno curves and some photos. I have not driven the car since 7 weeks though i had a gearbox failure but next week i will also add an Interceptor X.

Can you really drop the 0-60 time by almost half a second by gaining 7hp at 8000+ rpm?:spank:

No not really but everytime i "race" i improve on starting and shifting of course. Today i have mount the ACT flywheel and stock clutch, so now i'm only waiting for Wednesday next week to pick up my 8"

any more info on your header ?

pics we need pics .................

wow, this is taking a bit too long... :(

suckers are always willing to bite ...

wait wait wait....

suckers are always willing to suck...

cant bite due to lack of teeth...

stop spreading lies...

heh...

Thing is, i will wait for 1st week in August to have Peter G begin with my stainless Renesis header. I know i'm very lazy about posting pictures, but i have lot of work to do in my rotary business so sometimes a simple thing as posting a picture takes long time for me but i will do my very best.

Zzzzzzzzzzzzzzzzzzzzzzzzz

valid point - your contributions are most informative :rolleyes:

Now i'm heading to www.ferrita.se to pick up my first 5, 2.5" stainless steel sport exhaustsystem. They come with a 100 cells racecat and front 2.5" full flow silencer. Rear is a 2.5" pipe with a full flow rear single silencer not baffled as stock but same size as stock,along with double 3.5" chrome tips. This complete system picked up +10 hp on my RotoTest. I will have my new webmaster to take some pictures of the system and have it on display next week on my website www.wankelracing.se

3 months and still not 1 picture? Come on Lasse, you need to show us something........anything?

If only I could read that...:banghead:

What, you don't know Swedish? :uhh: :)

I lost most of it when I learned Russian

I know i must translate to English! But question is when?... Next week!

alrite, we got a pic!

so a 7hp inrease, eh? sounds pretty good. or did i just read 10?

The increase + 7 hp was after i added my Ferrita 2.5"sport complete exhaust system.

/Lasse

wait. what is the ferrita 2.5 exhaust system? so are you saying you got 7hp with the header, and the exhaust together?

I would think then that the header adds the standard 3hp. It looks really cool though.

The Ferrita complete exhaust system is 2.5" with a front race cat and a little round full flow silencer + a rear tube connecting to a dimensionally RX-8 stock rear muffler but with fullflow type,y tubing in muffler exiting to 2 rear 3.5" chrome tips. This system alone gave 10-12 flywheel hp more on my RotoTest. Then i added my prototype header and that added + 7 hp at flywheel. I will try to translate my homepage to English and ad some pictures of the exhaust system the coming week.

/Lasse

So, with the header and the exhaust system and highflow cat, we can expect 17 to 19 hp increase?

2.5 inch pipe is not unexpected. Most seem to think that they need 3 inch tubing. 2.5 inch should flatten out the powerband a bit. This is more in line with the figures that rotarygod comes up with. (Yes RG, some of us pay attention)

17 hp from exhaust system? But that is with a race/high flow cat --right? Plausible!
Curious with what you have done with the center port--can you give us another picture showing the header ports? if not then I understand--have to guard development secrets.
Important step toward that hp goal of yours and i am following closely. If that goal is obtained (and I am optimistically cautious:)) then i will not need to go FI.
header looks good for prototype. Are there air holes for the air pump present?

oooooooo okay:). sounds good man. as long as it really works. im first in line!!!
