Thread: Big turbo and HP guys (cam related)

I wish I could see my backpressure. If I had to guess I would guess 10psi or so backpressure with the exhaust hooked up.

I know a Good ems will be nice but the calum ecu its more than capable for my needs.
Thanks

what cams did you use to trap 136mph?

There is a guy on the old forum I know for a fact made just over 500 on a stock DET with like 25psi and it held together for a while too. He had only ARP studs and a headgasket I think and a pretty big turbo.

My motor was bone stock, with a 60mm turbo, and aem ems, that trap was on drag radials, you can search under my name to see some vids, pics, and my setup.

To ad some more info to this ..
Here its plot with boost vs back pressure As you can see the there is no negative delta-p on this setup so the c2 are in this moment my choise.. but Here its the question : how much more boost threshold its going to have ? 300 rpm? I dont mind to get full boost at 6000 rpm since with 8200 rpm for rev limiter Its going to be ok for the p11 gearing , Doing some maths and read and see some info my guess its that this c2 in my setup ( ported head 3 angle valve job BC springs retainers kit etc) will start to make more power from 5200-600 rpm up.
I really apreciate your imput guys. Thanks.






Hat-off !!!caughtbycops..136mhp its impressive for a stock motor...
How much did yur car weight?

2380 w/o me in it, i weight 180...I'm telling you standalone is the way to go, you'll be surprised how much power you can make over a jwt or calum, my next project should be out late spring early summer, going with a 9 sec setup. Good luck with your car.

I know what are you telling me man trust me I do for fact , but expeding 1500+ And start all over again Its not in my book for now ,maybe in a not to long future.
wherever cam I use s4 c1 c2 etc will give at least 50whp of peak power and probaly over 70-80whp over 7500rpm so that its 550 whp territory at 24-5lbs wich its plenty for now.
I would like to know your insight regarding to my setup.
Thanks.

On cams, I would purchase one of the jwt c-series, or brian crower stage 3. It would definetly wake up that motor. If your not a BC cam fan, the jwt cams, with the BC valvesprings and retainers, those are $230 which is a deal. Cause the JWT springs and retainers are over priced imo.

This is what I would do.

The c1 on paper look like a bad ass cam for my setup... Im looking for more info about this cams..
thanks.
