Warwick prep. Dyno results
RodPenrose - September 20th, 2010 at 08:52 AM

I have been way too busy to finish my new drag car and have had to go to plan B , and modify my circut car for the drags . I have removed the engine and transmission from the car and replaced it with a purpose built deal .
The engine I have just assembled from all of the parts laying around here has just returned from a dyno session where it produced 191 HP and 288 ft/lb's of torque . These figures were at the wheels and were made with a full cooling and charging system operating with a full sized pulley . The engine is built on a new Magnesuim case , 82mm Demello full circle wedgemated crank , 5.4" h beam rods , AA 94mm Racing pistons , Pauter cam similar to an FK 89 , a set of Welded and ported Comp Eliminator heads with 46 x 38 stainless valves and 12.8 comp . I was using the Sunoco supreme nos as the fuel and changed to BP 98 and picked up more power . The exhaust is a 1 7/8 header with a stinger and with the muffler the engine made 188 HP .
The transmission is built on a Rhino case , a full set of Albins gears and a locked diff . I am using the same 930 cv set up that was on the car . I am doing some maintance on the car and it will be in the trailer and ready by Wednesday , I will see you on the north side of the border , ROD.

jeez, nice hp numbers rod....


modulus - September 20th, 2010 at 06:24 PM

Blimey, 12.8:1 with 98 octane pump fuel... Don't you need avgas for that sort of C/R?

Yours uninformedly,

Great result Rod :tu::tu::tu:


Keith Haeusler - September 20th, 2010 at 06:56 PM

Rod,

Thanks again for the offer. Had a great day and was good to put names to faces.

Bring on Warick!

Regards, Keith


Gracey - September 20th, 2010 at 07:42 PM

Nice result, what intake are you using?


cnfabo - September 20th, 2010 at 09:56 PM

i think 51 ida's


RodPenrose - September 21st, 2010 at 08:23 AM

Gracey , I am using a new set of the Empi 51mm carbs . I tried several different size venturies and ended up with a set of 45mm that seem to be a compromise between drivability and high revs . The intake maiifold is an original Superflow component , welded and matched to the head , ROD.


Dak-A-Tak - September 21st, 2010 at 08:47 AM

Any other results of other cars there ? Rod .What octane , or figures on the sunoco fuel .
Good to see ,that you will be racing at Warwick.


SuperOwen - September 21st, 2010 at 11:48 AM

Not sure if the owners want details posted but all the other cars made good results, minor jetting and timing changes picking up good power in some instances. No breakages either!


Keith Haeusler - September 21st, 2010 at 05:14 PM

Hi,

Can`t speak for the others but i managed 177hp from my engine. Still a little rich so hopefully can squeeze some more out of it.

Cheers, Keith


FROSTY - September 21st, 2010 at 05:49 PM

Nice work Rod, I saw your car at the Raleigh track day...what a weapon, can't wait for you to cane the guts out of it at Warwick.


FROSTY - September 21st, 2010 at 05:51 PM

By the way has anyone got a photo of Rod's car??


Paulc1964au - September 21st, 2010 at 06:13 PM

thanks Paul !!


Dasdubber - September 21st, 2010 at 07:51 PM

Well done Rod, looking forward to catching up at Warwick and seeing how these dyno numbers translate into on the eighth mile.

Also good to hear your engine is running sweet Keith!

Thanks Rod,

Another question.......at what revs is it making max hp?

Nice one Larry!.
Do you think we could get 177hp out of my old tired 1916?, LOL.

Cheers Col


Klaus - September 22nd, 2010 at 04:34 PM

Went along to see if the old type4 made some more power.
engine is a tired 2ltr ex injected bottom end so has hydraulic lifters .
smallest heads as in port / valve for type4 just mild port job to blend exh ports
40mm italian webers with update kit
dis ix ignition
custom 1 5/8 tuned length extracters and modified muffler
last time out it made 55hp with 122 ftlbs but heads had blown hedgaskets burnt exh valves and cracked heads
this time with newer heads that seal
65.7 hp and 136ftlbs so happy that the shagged motor can still make good power for what it is
motor is in a 62 split panel with upright kit


whathaveidone - September 22nd, 2010 at 05:55 PM

managed to get 147 rwhp out of the drag rat bug, a little more than morgan, before he hit the cheeter button:lol:!!!!Now the cars are finished just have to get stuck into the trailers and tow vehicles, so we can get them up there.


Dak-A-Tak - September 22nd, 2010 at 08:32 PM

Ha , Ben how much nitrous did Morgan shoot ? Thanks for sharing .
Anyone have pic's


whathaveidone - September 22nd, 2010 at 08:50 PM

ill let him tell that! Dont think anyone got any photos but i did get a video of a monster truck driving up the street!!!!!


humpty - September 22nd, 2010 at 11:10 PM

Shit.... This really sucks... Gonna miss another Warwick.... But maybe I'll catch some of you guys at Portland?


RodPenrose - September 23rd, 2010 at 08:09 AM

Gracey , We were tuning from 70 to 160 km/h , and the engine was on 191 when we finished the run . This was at 7080 rpm's and I think there is more power available . The max torque of 288 was at 5750 rpm and didn't drop off much at 7080 . The engine will be good for 8500 rpm and I don't know where the max. power will be . I am changing wheels now to allow me to use a treaded slick to hold the power , ROD.


oldskl60 - September 23rd, 2010 at 10:40 AM

great news guys.

looking forward to warwick - sounds like there will be a good number of tough n/a "street" cars...

Shouldn't you have done full power runs to find out where the max power is Rod?? Seems kinda fruitless to only dyno to 7k when the thing will possibly run to 8500?? Peak power might only be at 8000 but I guess you won't find that out unless you do full power runs to the limiter. Hopefully you have enough fuel in the thing so it doesn't run real lean in that last 1500rpm or so or I might have to bring a mop and bucket for the clean up LOL
