Ok had my car on the dyno on friday morning, and managed 431 bhp on the back wheels @ 1.09bar

 

i was well chuffed.

------------------

BUFF MAN 300ZX SUPER HERO!!!! or is that DUFFMAN????

Well Done.

 

Short but sweet message.

Nice one mate.

 

Wot spec gets you that power? Is that your day to day setting or did you spice the car up for the RR?

 

------------------

crazyeddie.co.uk

Yeah post up your Tweekages mate.

Id be interested. I've got a couple of v.nice mods coming up soon

:)

431 rwhp! Thats over 500bhp at the engine! What are the mods?

Good effort fellow geeZer!

 

You who ask about mods, maybe you'll appreciate my struggle. WaZZa has had an engine explosion at some point due to his MINES ECU not interacting too well with the UK fuel.

 

I'm not being sour puss over this, I say top banana to the SA Universal Soldier....hope my car will do the same! But a classic example of mods equals lack of day-to-day reliability!

 

My car had an incompatibility problem with S.E

 

Nah car went belly up in Rome in Italy, due to 90 octane fuel and wrong plugs.

 

Secret to power is MINES ECU/550CC INJECTORS/HKS SUPER DRAGGER /HKS INTAKE/

And last but not least, keeping it away from S.E

Warren,

 

Did you find out what turbo's you have fitted? Stock ones won't produce that much power!

 

Steve

i have T28 turbos.

 

 

431bhp Warren you could get even more if you

take a trip to SE

 

------------------

he he he mac1 i actually dont think so

 

I somehow think i found something today on the trip home from duffman will have to see if it works, i think i had setup my boost controller completly wrong

 

What you mean like 1.9 bar as opposed to 1.09 ?

 

Warren, it it's not too personal...

 

 

...how much wonga do you think you've chucked at the motor to get it to this spec?

 

very impressive by the way

 

Tim

As you say that, not alot lol.

I was very lucky to buy this car with alot of the mods on it.

I will give you a rundown of what its got and how much its cost me, asap.

Andy p definatly 1.09 bar (this aint S.E were talking about )

Probably be even more if half yer exhaust hadn't fallen off !

Yeah half an exhaust and still more than yours

And a cheap jibe in return eh ?

 

Well we'll find out on the 24th won't we !

And what we will find out is that mine is virtually standard (and hasn't blown itself apart due to a dodgy MINES ecu!)

 

If mine makes 300bhp at the wheels then I'll be deleriously happy !!!! In fact if it doesn't blow the turbo seals out the back then I'll be pretty happy !!

OH REALLY. i c that the main man has a super drager, jus like me. ha ha, no more lop sided jokes thank you [topsquads].

 

ps. i thought it was super drager, not dragger. or have i got a bad case of the tommy hilfliggers.

er, yeah. anyway.

 

 

i thaught my disabled finger typed that in

 

oh yeah, bye the way..... does anyone know anyone with those crazy zed's on the max power dvd. red se-nissan and red other one???

ok just added my dyno run on the top.

WaZZa,

never played with a dyno before so excuse dumb questions ...

 

Noticed that your dyno run was in 4th gear, any resaon for that ? Like maybe they don't want the rollers turning at 160mph+ ??

 

Do you need to do anything different for an auto ? Because it's not likely to be a 'single gear' run - you'll see peaks and troughs in the torque and power curves as it changes gear.

 

How do they apply the 'correction' for transmission loss ? Obviously this will differ from model to model and between manual and auto.

4th is used because on most cars it's the closest to a 1:1 ratio

 

On a Jap auto - they should put the box in hold (keeps it in the higest gear), so you'll get a strange graph, because of it changing from 2nd to 3rd (or whichever change it makes in hold).. Or you have to yell at the operator when it shifts into 4th to start the Dyno recording.. (thats a sort of quote from Phuong BTW)..

 

As for tranny losses - most flywheel figures are, to put it politely, guesses..

 

Basically the idea is that you (if I recall) put the clutch down, and let the wheels roll down to zero on their own accord.. The computer then uses that time to determine the drag of the drivetrain, and therefore the flywheel figure..

 

The best article I've ever read on Dynos and how they work etc can be found here;

http://www.gtturbo.org/articles/article.asp?id=40

 

It gives a better explanation of why flywheel figures aren't that great a thing to rely on, and why if you want to compare power with your mates, it needs to be done on the same dyno, same operator etc..

 

Az

BTW Warren, most impressed with 310 bhp in what is essentially safety boost!

It will be interesting to see Warrens figures for that dyno and the one at Hemel.

Will also like to see the barometric pressure and temp figures.

 

Just has a thought about the MR2 Turbo as well - does the place direct air towards the back/sides of the car ? Being a mid-engine that's where the air intakes are ...

AZ i couldent have put it better

Andy it is pretty cold and assuming the fan works it should be alright for the mr2.

 

This was a run at the hammel hamsted place, i passed them on the way up to Duffmans do.

I phoned him again today querying my power output (basically because no one believes me, so now i doubt myself) and he says they test many cars which come out very close to exact spec, and he says obviously each dyno will vary, but he is quite sure the run was pretty accurate.

He also said its the strongest car theyve had on the rollers

 

also regarding flywheels power, he recons it is not as high as some people like to believe.

Im going to try get my cats gutted before the next run.
