Tonight we dynoed the car again!

at 21psi and 77% duty cycle (6x1680cc) it produced 548rwhp and 390rwtorque (ftlbs) or 528,8nm

Thanks to ML wankeltrim and Lasse wankel for letting me dyno the car at the rototest (hub dyno).

That is pretty impressive. Do you have an Xcessive LIM? If not where did you add your two additional injectors?

Does anyone know how much more power his T78 has left in it?

I wonder what those numbers would look like with a GT42R style turbo?

How do you guys fit 1680cc injectors into the center housing/primary location? I cant find anything on the subject. Thanks.

it is tight as hell but it works.

Lasse wankel

No knock according to the pfc at L15 deg,split is 10 deg, tested 12 deg but lost power. Exhaust temp is at 900 C at 7500 rpm. Maybe the engine would have liked more ignition but we stopped there. The engine accelerates real hard 4000-7000 rpm then it starts slowing off. Max power at 7350 rpm and torque at 7100rpm. Think the T-78 is really maxed out! A Garrett GT42 would be interesting to test this winter wouldnt it Gus?

Thanks for the quick reply....

I actually meant fitting the large belly injectors in the primary fuel rail(the one with only two injectors)... The housing on the RX-8 has two holes for the primary injectors but the big ones don't fit(the stock ones are thin and long. How do you fit yours?

Thanks

Did you record the intake temps?

gusfd3s

hmm, they fit? as i remember it..? you can use the o-ring that holds stock injectors.
Are you talking about rx8? then i dont know.

35dgr C/95dgr F

Lasse wankel

What you say Gus shall we but some E98 and do some more Testing "lol"

ChrisRX8PR

I see....your stock primaries must be larger that the stock RX-8 ones....ours look like the subaru denso ones that are thin and long...

Thanks for the assistance. Anyone else know?

Was that at the end of the run?

35 celcius ? Wow, that's cold ! How warm was it outside?

gusfd3s

A bit colder than the other runs, used to be around 40dgr. it was only 15dgr and rain outside. the temp is slow to update so logs show 35dgr through whole map.

Damn, is it winter there?

gusfd3s

sometimes you start to wonder, 4-5 days ago it was over 30dgr c.. when taking the car to the track, directly down to 15dgr and rain

Lasse wankel

Must for your knowledge inform that it was 24 deg Celsius in the dyno room,40% humidity and 998 mbar.

I've got a renesis at the shop I can take a look at and see if the bosch ev1 style injector can be made to fit. We have a 1000cc injector that is thinner and will fit. It is also much more better suited for a primary injector..


Oh and great numbers!

ChrisRX8PR

How much for a set of the 1000cc primary injectors that you are talking about?

I need a pair. The Square plug 1000cc fat ones don't fit in the renesis, I tried....I was asking to see if people modified the center plate or the injectors to fit....assuming they had to.

Thanks

PM sent.

geez you would think if they went through the trouble of making their own manifold they would design it so its not so tight. o well.. i still need one of these.
