Dyno results

Hi there just thought id let u know what i got at my Dyno today.

145 hp 6000 rpm
136 ft of torque @ 5000 rpm

That is a 17 hp increase over my standard SRi figure of 128 hp!:cool:

I'll scan in the graph tomoz and post it up.

Oh and I forgot my HSH is coming tomoz hopefully, ill get it dynod again when its fitted to see how much a HSH gives on a UK dyno.

Those are VERY good numbers!

looks good Neil, hope your happy with the result so far. Gonna be interesting to see what the headers gonna give you. Will it be on the same dyno? best if it is.

Are those WHP? What mods do you have?

No they are flywheel figures. My mods are listed at the bottom of my posts.

Oh, then they are OK I guess. :p I though they were whp figures. So what were the wheel numbers? Do you still have the plots?

145 hp is good considering I started with 128 hp!

What's the diference between your car's engine and a "normal" P11 engine (145 factory FW HP)?:confused:

Ahh well yes then it would be quite good. I'll ask again do you have the charts with the dyno plots on them? :confused:

Neils Sr20 is factory 130 BHP at the flywheel, its not the 150 BHP SR20 so an increase of 15 BHP above standard, not bad at all.

Nice one Neil !, makes it all worth while :)
How soon before the header goes on ?

Congrats Neil.....:frog: WAY to go! :cool:

But now your car has more BHP than mine :finger: But just wait.. he he he :devil:

It is nice figures neil thumbs up:ylsuper

Got the header today :D It's also my bday, and im now officially skint so the header will have to wait a wee while to get fitted. But I cant complain I have spent about 400 on the engine so far and made 145 hp and 136 ft of torque (1 more than a GT :-)) but I dont like to brag ;)

Hey HAPPY birthday there Neil!! :frog: That was a good present that header!! ;) Hope you will have a nice day! ;)

Thanks m8:) I promise that I will scan the dyno in tonight when my bro gets back from work, and he can show me where he has hid the software for it:mad: :mad:

Like I said on Messenger, they are some pretty impressive numbers.

The torque figure is very impressive, although your engine seems to have trouble at high revs (hence max power is only at 6050rpm) which is going to ultimately limit the bhp you get (since bhp=torque*rpm/5250).

Once you get the car properly mapped and the Hotshot header installed, hopefully that will sort out your top end breathing problems and you should be outputting some impressive figures indeed. I reckon that you should be able to make power for another 300-400rpm at least.

And yes Neil, you have a faster SRi than me, OK? :o

And of course, happy birthday, and I'm sure you'll enjoy your "present" tonight ;)

Looking forward to see youyr Dyno! :)

This is just an idea, but have you tried to download the SW for you scanner on the internet!?*LOL* It is the worlds biggest storage place!! ;)

here is the dyno sheet, the P@wheels figure seems a bit low but most of the big power cars at the dyno meet did the same for some reason!

Hey Neil,

Nice figures....... :)

But how come your car already cuts off at 6200 rpm!?

We had a Primera 2.0 from 97' that made the same with the torque graph around 4200 rpm.

We found out that it was because of a worn chain drive and chain "controller" (don't know the English word*LOL*) - After we changed the parts the torque line was all flat out! :)

I did'nt knew about that engine. Why so low on power?

It's the engine they put in the lower versions of the Primera like the GX,SRi etc it actaully has 128 hp (130 ps) and the P11 GT has 148 hp (150 ps). Its basically the same as the GT but with more restrictive exahust etc to restrict power.

TeamNissan the reason it stops at 6200 is casue thats when the power drops off so they dont bother reving it any further. When i get the hsh on ill get it dynod again but this time get them to redline it to 7100.

What ya talking about the flat spot in the torque? Kevins Primera GT had the same flat spot as me the only way to sort that is a 'uni-chip' which i will be fitting as soon as I can.

I think there is a possibility your car may have the 128 hp engine?

My primera is a GX, but it has the 145hp, I have race a VW GTI (1.8T) and have lost only by have a car lenght.

What makes you think that? How can you determine the diference between the 2 engines? Do you have any pic of your engine?:confused: :rolleyes:

WOW..145hp at crank only gives 99whp?
what about those ppl like jason that has 141whp? that's 50whp over it....
they must be doing over 200hp at the crank?
:eek:

aaaaaaaaaaahhhhh OK just found it strange! :)

Anyway mine already cuts off at 6800 :(

Damn you have a LOT of mods there Neil! ;)

Yep the flat spot on the torque!! We found out, that because it was worn the timing was a little off, so we changed the chain "things" I wrote about before and the graph was continous without the flat spot! :)

I will try to find the Dyno's and scan them so you can see the diference! :)
