Thread: Went to the dyno last night, tell me what you think

You are right and I cant argue with your statement.

It is beautifull to see this cam combo come out. I know when it is done this will be the cam that many people will be buying from Franklin.

I see the price of N1s dropping as Franklin 20V bottoms and N1 tops come along

Time to sell the N1's

[QUOTE=Clint;
Kelford's 184-C made exactly 1kw less than the N1 at dyno day and stopped making power at 7,300rpm. I have to work out why as they are supposed to make power to 9,000rpm. Picking it could be either exhaust or cam timing.QUOTE]

Question ? Did these cams come with cam specs? Degree card? Good cam manufacturers always have the spec. with their cams. Were these cams degreed to these specs? Post up the spec card, please.

Just a thought.

Ok, ok, im ringing the dyno shop now, see if he can fit me in.....

maybe get a webcam hooked up at the dyno place and get a live feed on here...

Crikey you lot are demanding :

The phone is busy, im still trying..... suppose you want me to take the vid cam too then...

Work it Evlnxr.

forget the vid cam.

We are one step away from the best drop in cam, so yeah we are going crazy.

Once it is finally confirmed we can move on to something bigger. Maybe I can get on in a MSN chat with the guys at Franklin and see if we can iron out a cams shaft suited more for a bigger motors like 2.0-2.3L

Argh, their phone was playing up, went to see him and he had some crappy big push rod v8 truck on the dyno and was not happy about it, so didnt ask. I'll have to see how he is next week.

They do feel very very good on the road. Ive found the intake cam must be switched between 6100 and 7000 or it looses power, and also switching the exhaust at 5700 feels way better than 6500, and keeps it on cam thru the gears without revving it to 9k.

Dyno will tell i suppose. I might look into getting a data logger, we were looking at the data last night, afm vs revs, and O2. You can see on the data the power as the numbers get hit on the afm voltage, so looking at the fattest part to the numbers is almost like a dyno chart.

Arg, im even thinking of getting a chip burner....

I want say good job to everybody that participated on dyno day.

After looking at the dyno day video. I'm surprise no one has mentioned or noticed the peak power rpm on the cars. They are optimistic by at least 500 rpm. Here’s a comparison.

New Zealand:

N1 cams peak at 8,500
20V 8,000
20V Wagon 8,500
Stage 4 8,500 to 9,000
SR16 7,500
Stock cams 7,500

US:

N1 7,500
20V 7,200
Stage 4 7,800 flattening to 8,500
SR16 7,300
Stock 7,000

I suspect the New Zealand dyno graphs is off on the rpm grid. It would also explain why the New Zealand cars need to activate so high up on the rpm. In actually, the rpm graph is optimistic.
