Not bad for an LS2 and a Harrop 122...

My ute makes 700 & my Gtr 750 and the Gtr would make it look silly , amazing car but no soul or style even though I own one but what a car for the money.stigmundfreud said:

its like the video of Honda civics beating corvettes, just as in those videos the gtr driver goes home in style leaving the modded car to park up at halfords
Effective tool maybe but it is far from stylish.Raving, didn't see it was a centri, they are so overlooked here perhaps a brave soul should go centri and see how they compare against the pd lot

I ve always had centris and run a T Trim one on my ute ,I didnt like pd , and I believe some have removed for Pd .Raving, didn't see it was a centri, they are so overlooked here perhaps a brave soul should go centri and see how they compare against the pd lot
With a pd any half brained spanner man could bolt one on I think that is half the apeal the ease of fitment.
As to the centri the intercooler pipe run can be a headache & belt alignment

Don't go daft chasing power and it should be a weapon. If you overdrive PD blowers they just turn into heat pumps at WOT and lose power, less is definitely more. For VMax you are probably better off with a big centri and the right gearing.

As seen by his consistency, water/meth has largely taken care of thatI've always liked this: https://www.youtube.com/watch?v=M8USkNiuGEc
Centri/turbo, either are better suited though, but the PD's can still have fun too.

I've had 4 different PD setups and the current one is by far the best as it was built from scratch to work as a package. Stroke, capacity, cam, air flow and compression ratio, were all by design and built around the TVS2300, the largest blower that will sit under my bonnet. It makes over 600whp with no real traction issues in the dry, and spits flames for the exhausts at full throttle. Even intake temps aren't too bad but I do admit it struggles with heat soak on hot days which is why the chiller is going on. Apart from that it's mega, pulls all the way to 7k rpm and proof that PD blowers can work brilliantly when set up correctly.As to the centri the intercooler pipe run can be a headache & belt alignment

If it works for you, that's all that really matters. Richie Slow has it right, by not measuring against others, but by the seat of his pants, as that's what matters. Forget pub figures, do what's good for you.I did hear that a 112 will give you a bigger hit but tail off, whereas a 2300 will give you linear power - yet what is better?. I think you relate to bikes, and remember getting rid of a well mapped ZX9R in the early 90s (because it pulled like a steam train), and buying a 2 stroke instead as it gave you a big hit - even though it was less than half the power.
Surely what matters is what it means to you? If you were really bothered, you wouldn't be driving a Vauxhall.

my car does what i want it to do for me
In many ways, worst thing I ever did was fit scan gauges. You spend all your time looking at oil pressure and IATs, there's a reason they are called "worry gauges".
TVS2300 is a little bigger than the 122hh but more important is the thermal efficiency which comes into play when you try to wring the most air flow from them.

( although I have to question the equation of cost Vs. performance of the work to produce those graphs posted a few posts ago...and wtf is going on with that power curve? )
It's the old case of diminishing returns. Stock internals work same as forged ones up to a point but they will only take you so far without certain failure. No such thing as cheap, reliable performance.( although I have to question the equation of cost Vs. performance of the work to produce those graphs posted a few posts ago...and wtf is going on with that power curve? )

Diminishing returns. Knowing when to quit is the all important point. wormus said:

It's a good job the TVS3300 heartbeat supercharger won't be made or I'd be in deep trouble all over again!ARAF said:
