Almeragt´s SR20VE Almera

No Dyno run yet?

not yet... It was moved to the next week - Dyno had some technical problem... :( Other Dyno s were overbooked - they were tuning some racing cars, so I will go probably on 2 different dyno s next week... Want to see the difference in dyno readings...
 
OK, so was on the same dyno yesterday... This dyno is known to read LOW numbers, what is O.K. But where I see the problems are RPMS - dyno reads max 8935 RPMS, what is not right, because my rev limiter is set at 8500 RPM regarding ECU. So torque curve and maximum value of torque was not loaded correctly...
Anyway - maximum power is 229 PS at 8500 RPM /real value, over 8900 reads dyno meter/ and it´s still rising. I don´t have dual springs, so don´t want to rev over 8500 RPMs.
So modified intake is good for 15 PS, but for feeling is like + 35 PS :)... I will be on another dyno meter next week and looking forward to see the differences...

where the PS and Nm cross over (showing as 7,000rpm) will be 5252rpm...........

very nice gains with the intake, exhaust and mapping - massive transmission losses?

thanks... where the PS and NM cross over is around 6550 RPM...

not massive tranny losses - it´s the matter of dyno meter - don´t know why, but MAHA LPS 3000 dyno meter always reads much lower whp power comparing to other dynometers... I´m using standard SR16VE LSD box, so nothing special... normally it should read around 200 WHP... But as I said, MAHA LPS 3000 always reads low whp output... 229 HP is crank power... I´m really curios, what will read other dyno meter next week... /I don´t really care about the numbers, but want to see what is the difference and how it is possible/
 
not massive?! its 63hp, normall about 19-22hp.

as long as both are using the same scale they will ALWAYS cross over at 5252 RPM. If you are using a chassis dyno, stick to WHP, it is the only accurate reading you'll get from it regarding power *return visit.

201.5nm x 6650 / 5252 = 255ps?
(6650 max torque)

Yes, this dyno reads massive whp losses,.. Don't know why... But it's not accurate for sure...

As I said, torque is not right.. Dyno reads 8935 RPM / what is not right/ against 8500 RPM, that means that torque curve is loaded in longer RPMs, longer graph and reads lower torque in NM. Regarding log from the mapping /Nistune/, my maximum torque is really from 6800 RPMs and it's not decreasing up to 8500 RPMs, but dyno reads somthing different...
 
i think 201nm is accurate almeragt. the torque and ps would have crossed over @ 5252rpm had the graph been plotted in the right place.

Which line is which? If you are still making power up to 8500RPM then you'd be better off shortening your intake runners to shift the power down the rev range.

it´s not accurate, also guy who was doing measurement told me that if dyno reads more RPMs than is real, the torque curve will be not right and torque value will be lower... OEM SR20VE should have 196 NM and 190 PS... I do have around 230 PS and it could have around 220 NM in reality... All my friends who were make dyno run on other dynos made more power and torque around 220 NM

spook: yes, if you see only one line is rising up to the limiter... that is power curve... I don´t want to make any changes...
 
i thought lb-ft and nm were the same thing, only expressed differently? like psi and bar, when you hit max psi this will be the same time/rpm as max bar..... if not no hardship.

more ps doesnt mean more nm. on your first page it shows 215ps and 195nm............

They are just different units. 1nm is 0.7ftlbs. The calculation of torque x revs/5250 is based on ftlb units.
You can make it cross at 5250 in Nm, but the hp and tq scales would need to be offset.
 
looking forward to seeing another dyno chart (that i can read lol)

luving this buildup. you should post more on the pga (aus)
 
Good results! When I had dyno done last they did printout in NM I asked for one in ftlbs... if they still got your results on file ask them for printout in ftlbs :) shouldn't need to be redynoed if they have it on file still
 
So the car is finally on the road! Many THANKS to Raddy, Roman and Jagy. Without you guys it would be impossible to make this project real! Thanks!

Car has complete new map for modified Xcessive plenum with velocity stacks, 4 inch intake pipe with integrated MAF and Q45 TB... The car is now a real beast! Pulling like a train... Will be on dyno next week...

Have made some photos - quality is poor /didn´t have much time, so I took some pictures by phone only/, but anyway I will hope you will like it...

that slot maf adapter you got to fit the maf to the intake pipe, where the hell did you get it from? link?
 
Even the wiper motor is on the other side.

Could you measure the distance of the left hand end of the plenum to the firewall.. Need to see if that plenum will fit on a rhd n15 clearing the brake booster.
