And then enjoy adding over a second onto your 60-100 times. Doesnt look like mines choking here reaching 7k nicely.

Fil, don't forget that you have a 4.05 FD gearbox, greg should have a 3.82 FD box. Meaning that he will hit 100mph in 3rd below 6krpm. (around 5800 ish from what i remember)

If you motor is in fair condition (mine had a hg change and new standard valve springs) go for it. My 19t was still pulling nicely over 6k so I let it rev to 7k. If your not comfortable doing it mate, don't. It's your motor arguer the end of the day. Summat tells me you'll be spanking the **** off it though as on paper it should be a little better than my 19t

Very true Kyle but the point kinda still stands. Just using the 60-100 as a reference point. If its still pulling nicely past 6k let her rev.

Just out of curiosity,

If I was to install the GS valve springs. Could rev to 7k all day long?

Minimal risk ?

They are only 90 bucks (plus 200 bucks install + or -)

 

[Dr Kenneth Noisewater]

WOW 90 bucks IS cheap. We pay 90 quid in the UK for stiffer uprated Volvo springs. I'm guessing the GS springs are the same. If they are you can rev it to 7.5k iirc. I'll have to have a look at those.

I got my info from TrollTuner:

http://trolltuner.com/?p=901

"Stock Pressure plate (This includes Spec blue painted stock ones) should not be run past 7000rpm EVER, That means 6800 max since there is a 200 cushion in trionic. The plate deflects considerably. Running them over this is a great safety risk. We experienced multiple dowel pin failure and plate explosion on the drag car as we found this out. Cost a few gearboxes, flywheels etc…"

in stock form you can rev to 7k all day

the better valve spring will help take the engine beyond that (7.5K)

Does this include the Viggen PP as well?

Good question. It is not clear to me from the link on TrollTuner but I do think by "Stock' he means "Viggen". We need Nick to chime in.

Agreed. As nicks base model is the vig I think its fair to assume that "stock" is the vig pp. As ive said though me and many others have hit 7k on the vig pp without any problems. Might be a different story if your hitting it hard on higher torqued applications.

OK guys, I've had a night to sleep on it. (early Saturday here).
I'm going to go with a 6500 limit. Just to be on the safe side. I'm not going to need to rev it any more than that. Not with my little turbo.

In saying that, I totally agree that you can rev 7k, But that makes me real nervous and unnecessary for me.

If I'm driving it hard, I'm gunna shift @6300k with a 6500 limit.


Someone agree with me

Can I smell chicken???????????

Yes.:lol:

The bottom line is that with T5 cams and the T28 turbo, it will be pointless to rev it past 6500 from a power production standpoint.

Though it may not be "out of breath" between 6K and 7K, the peak HP will not be found much, if any past 6K. Actually, peak road HP is likely made around 5800 RPMs.

On the other side of the equation, I will add that I have analysed my acceleration and found that it falls off only a few percentage points between 6K and 6.5K.

Peak power comes in @ 5870 from my logs-only a tick or two. Most of it is from ~5k; fairly flat across the magic 5250 mark.
