here is graph - 7psi vs 14psi - on dans car.


dotted lines = 7psi
solid lines = 14psi
all figures measured at wheels

mmmm torque anybody? :P

- colin

whoa! thats pretty bloody impressive. that must be fun at 14psi! and i imagine actually fairly driveable too?

its not too bad, the power comes in very evenly over a 2000rpm spread, so quite controllable. i love these set ups. they are all you really need on the road - and still plenty for track too.

- colin

JESUS H...

thats some difference there.. they do say torque comes with boost.
good to see that actually. kind of prepares me what to expect. and if dan is happy with what he has now then he's going to wet his pants with the higher boost.


colin, is there any way for you to overlap dans, low and high boost graph over the top of a descent spec throttle bodies car??

That torque on the 14psi run looks very noticable lol its mad how much torque increases with psi, would be fun to play between 2500 - 4500 rpm Big smile would be planted on your face me thinks!

just shy of 300bhp per ton in a stripped sax/106 would be more than enough to scare you silly, 400+ cant practically be much faster CAN it??? mabee topend but in the realworld?
dont take that as a derogatory question, id love stuupid power but surely theres a limit to the practicality?

goin good. not touched the engine bay, just cosmetics, and a bit of slammin ;)

we should have another watford meet again sometime lol :y:

oh trust me it can be much much MUCH faster :P

imo around 280 on the wheels is practical limit for these in road trim.

after then they start becoming rapidly more awkward to drive and you find yourself limited where you can actually use the power... a road you used to consider fine is now hurrendously bumpy and waiting to throw you off into the horizon, you have to be so careful.

as requested



stock engine at 7psi (broken lines)
and 14psi (solid)
-VS-
division 1A super 1600 C2 rallycross car (dots) (150 hp @ wheels - 9000rpm engine)

bare in mind, engine of that spec is similar cost as dans conversion ;)

What difference between 7psi and 14psi, Torque is real rapid:P really impressed with Colin/Ian Atspeed's Work:y: looking forward to getting mine down now hopefully should not be long Colin;) need to pull my finger out abit:P real like this car Dan, hows getting in and out of cage Dan;)?

I dont think your car exists.........lol

Come on Wayne rob a bank or something.

any other requests? lol

cheers colin. thats extremely interesting. very nice to see an overlap as it just shows that the boosted car is much better in every aspect.


wayne, you sure do pal.. get on it lol :D

I have found seven posts where bum is being sucked with regards to getting your car down to Atspeed just in this thread! Get your us down there and get it all done :homme:

bodies ain't got nothing on boost there :D

colin sorry to cheeky can we have an overlay with one of your graphs if poss?

anyway paxo I bet you are over the moon!

How cruel:(lol;) i'm trying nearly there i think on saving up:panic:

Boosted Saxo's/106's are the way forward:P agree danny i get very interested with these graphs especially boost.

Sorry Jason i'll get my but down there as soon as my funds are good and ready, few more months time and car will be with Colin guranteed:D

well hopefully ill have my car on the dyno later this week (driveshafts finally turning up yay!) so will FINALLY be able to see what this set up makes.

- colin

then colin is going to kindly dontate his whole setup to me.....

okay, maybe not. but will be very interesting to see what happens.




on a side note,
dan you must be very pleased? have you not tryed the higher boost setting at all?? i should be ok so long as your not launching it and have normal road tyres.

its been said a few times..... but fuck me that torque figure looks awesome at 14psi, definatly a nice spread of power, rises sharply and stays in for a good while before nicely tapering off

exactly how a turbo car should run :y:

ive seen your vids, it looks like your trying to drive a lion!!!!!!!!! just mental, and trying to kill you at every opertunity, looks fun though!
