hi first of all this may have been done to death but i couldnt find much using the search,
currently my longblock was set up for N/A at 9.5:1 i have decreased this to 8:1 when i fitted the T04B but since im going bigger and putting a lot of time into the car im going to split the case and change the cam
basic spec is
2332cc
denham heads (og castings) welded and ported
cb case
DTA EFI
NOS
intercooled
water injection
turbo spec as follows
Compressor Wheel Inducer - 65.0mm
Compressor Wheel Exducer - 92.0mm
Turbine Wheel - 83mm
T4 Twin Scroll .90ar
what cam would you guys go for and is it worth going to roller cam?
cheers andy

I know Matt Keene (All Torque on here) uses a JPM cam in his wasserboxer, and picked up a load of horsepower. He'll probably chime in with what exactly he did, but if I'd got a motor of your spec, I'd certainly be looking at JPM. Not cheap though...

Copy of email from Johannes when I enquired about price.
Ive decided not to go to all the extra expense and just get a WebCam 86B on 112 lc
I think i read somewhere that Matt originally ran a WebCam custom 86B/86C which was replaced by the Raptor.
Hello,
JPM01012T
Matched lifters, brake in oil and paste are included in the kit.
Raptor cam kit is 4995sek or aprox £454pound, custom is £635pound.
Shipping to UK aprox 33pound.
Thanks
Johannes

Did you decide not to buy a Raptor even though you have read about Matt and his experience? Did you miss the fact that without changing anything but the cam he dyno`d a lot more HP? |

Nope, I didnt miss any of that. Without doubt Johannes' cams are extremely good , I just dont need (or for that matter can I afford) a cam that will make 450hp when all I NEED is 400hp. I think there are too many guys out there who feel the need to go balls out on everything ! If it was a custom grind WebCam 86b / 86c ( and i'm not sure if it was ) then I'm not surprised he got a better result with a different cam !! regds |

In my opinion the more rpm the more horsepower. I would go like this..... Beginning of 2500 maybe 3000 rpm to 6500 rpm Street Racing Car.... From 3000-3500 to 7500 - 8000 Drag Race Car........ How would you bullets. (1,600cc x 5500rpm x10,5CR)\910=101.5HP (1,600cc x 6500rpm x10,5CR)\910=119.9HP (1,600cc x 7500rpm x10,5CR)\910=138.4HP (1,600cc x 8500rpm x10,5CR)\910=156.9HP This looks at Honda VTEC VTI --- Always leave more horsepower In my opinion here would look like this 1Bar - boost 8:1 CR 8x(1+1)=16 Real compression (16:1)CR (2.332x6500x16)/910=266HP According to experience 310HP (2.332x7500x16)/910=307HP According to experience 358HP (2.332x8000x16)/910=328HP According to experience 382HP Whenever possible horsepower |

So very wrong mrmut
I doubt you tripled your horsepower with 1 bar of boost, at best double
If you double the compression from 8 to 16 to 1 you would only gain about 25.4% gain in power NOT the same as boost either!

1Bar - boost
8:1 CR
8x(1+1)=16 Real compression (16:1)CR
I think with T4 turbo spec as follows
Compressor Wheel Inducer - 65.0mm
Compressor Wheel Exducer - 92.0mm
Turbine Wheel - 83mm
T4 Twin Scroll .90ar
We will achieve these results (2.332x6500x16)/910=266HP According to experience 310HP (2.332x7500x16)/910=307HP According to experience 358HP (2.332x8000x16)/910=328HP According to experience 382HP You would grsham.
Prove to me your claim of 25.4% |
