Dyno graphs?

Looks great guys!

Surprized at the 7psi, not complaining but thought most of the testing was around 4.5-5 with around the same WHP.

Reguardless a very well put together and engineered product.

Dang very nice kit but wish it was 8k and not 10k ;p

The peak pressure varies a bit with temperature. The highest we have seen in 65deg temps is about 7.5psi, but that will go up a bit as it gets colder.

I will post some dyno results soon. We are actually playing with it a bit and trying to get power up a bit more, so we may see numbers a bit higher than 528whp/480wtq.

We could have gotten the price to around $8k if we cut a lot of corners, but then it would be half-*** -- we will leave that to others

I know that the price tag seems high, but consider that it is very competitively priced compared to similar kits for BMW M3's for example... and also keep in mind that the ISF is a very rare car, and we put huge resources into development and testing.

There are lots of guys modifying Subaru's and EVO's and while that may seem to be less costly, in reality it is more costly because at high power levels those cars are ticking timebombs. The reality is that most engine builds, assuming they are done right (which is often NOT the case) will cost more. I am very confidant that even a high mileage ISF making 500+whp with our kit is much more reliable in every way compared to an STi or EVO with similar power -- and in another league of reliability compared to a supercharged E92 M3

I can echo that statement above, I was at Discount Tire over the weekend and was talking to the guy helping me and he was telling me that his 485 whp Subaru WRX just blew 2nd gear at the track and he just got it back after a $3,500 tranny rebuild/fix!

After he fixes his $3500 tranny, he'll be putting $8k into his engine, if he hasn't already, its only a matter of time

Any idea on install time and cost?

Man, this is great! I'd love to say I'd purchase now, but I don't fancy a divorce! Haha. Soon I can saw I'll seriously be in the market!

How straight forward is the install? I'm in so cal, and there isn't too many ISF specialized installers.

We have you taken care of in terms of install. We'll recommend you to some good installers. I might be a guinea pig for install anyways..

^i figured this much! Do it Josh! I've ruled out a GSF and decided to keep the ISF and this is the reason why!

Awesome. I'm sure a lot of people will be very pleased with this news.
A couple of questions that may help others too:

1. How maxxed out is the fuel system in the advertised setup? Is there scope for more? Leading to...
2. Will there be an option down the track for a smaller supercharger pulley for say 10psi for street guys that wont ever see the track and beat on the engine as hard as you guys do?
3. Considering that the ISF is quite sensitive to knock in NA form, is there scope for more power with 100 R+M/2 octane, 100oct mixes (or even E85 mixes if fuelling headroom allows) since now the car is FI and still 11.8:1 compression?

Thanks RR Racing for all your hard work!

Amazing work RR, The kits looks beautiful

Will be jumping on this very very soon.
