Injectors and supercharger

Paros · Post by **Paros** » Tue Oct 11, 2011 1:10 pm

Need some help with info on a Ariel Atom 2 300 (UK version)

What size is the injectors?
What size is the pulley for the supercharger (is it a Jackson supercharger from the factory)?
How many psi is the compressor running on?

Would also like to know this if anyone knows

Hi Guys,

Stock injectors are 550cc
The pulley is 3.2" (I believe) but I have seen 3.4" available
If I'm right about the pulley then the charger is 8/9 psi

Excellent

Thanks for the reply

Don't suppose you know what injectors the 245bhp has?

Don't know. Should be able to read it off the label without removing (I could with mine) or a quick call to factory to get spec and price

OE K20a (applys also to the k20z) injectors are 310cc

As has been mentioned the stock injectors are 310. The 430 injectors from the Acura RDX(US spec) are a direct swap--you can use connector clips or pigtails. Apparently, the spray pattern is a bit better and you can get an extra 5hp out of the swap.

I broke two pintles when I changed my intake manifold. Since the pintles are not available separately; i upgraded injectors at the same time. I recommend the clips as it is a plug and play option.

Is the brand for the injectors 'RC' ?

Mine had RC fitted when I got it, and the dismal report from the firm that cleaned them suggested to me they were original factory fitted, but as I didn't buy it new I can't confirm for sure

Spoke to the factory. They stated original injectors on the AA2 300 are the RC 550cc ones.

Forgot to ask when I spoke to the factory but I'm looking for the 550cc injectors but there are different ones.

Smokin do you remember if your ones were like :

SL4 550 or SL9 550

???

SL4 550. CPL have them in stock @ £309 (inc VAT) for a set of 4 (http://www.cplracing.co.uk/products.php?productid=154). Can't recall the factory price but I do recall being shocked at how much more the factory were charging
