the shape of the small port inlet runner is a better base to start with than the big port, its not all about runner entry size, contry to popular belief the big port head is actually smaller in the crictical choke point on the short turn radius and therefore will hit sonic choke and become quite restrictive.

Man thats a whole lotta power for 550cc injectors!! I guess "a bit more pressure" is a LOT more pressure? :lol:

Is that atw or flywheel? Eitherway awesome result

by **4agtepwr** » Mon Jun 02, 2008 10:19 pm

Have seen 550s go past 460whp on an sr20 with fuel pressure, and yeah that was atw on mine.
Heres the dyno sheet as promised

Cheers

Still waiting on my beers from the dude who said a Box for 300kw......... :lol:

what about the KE70 in the current NZPC mag, 331kw at rear wheels? (not sure if that figure is with nitrous or not tho)

by **gasman** » Tue Jul 01, 2008 12:37 pm

imo nos is cheating

good effort considering its supposedly got stock internals!

by **IH8TEC** » Tue Jul 01, 2008 6:25 pm

it HAS got stock internals, also got 310kw atw on 20psi with nos according to kent when i was asking him while tuning my car.

by **escortman** » Tue Jul 01, 2008 6:29 pm

yeh thats things damn cool and how is nos cheating, same as adding a turbo

OMG so shiny! · by **Dell'Orto** » Tue Jul 01, 2008 7:20 pm

A. its not NOS, its nitrous :evil:

(pet peeve, so sue me)
B. Nitrous is entirely not the same as adding a turbo, they work in totally different ways. One is mechanical, one is chemical, you dont have to go to the shop and buy more turbo after 2 minutes (well hopefully you dont!)and you can't use nitrous whenever you feel like it.

I think he means as N2O is a power adder in the same way a turbo is. Rather than a "pure" NA engine.

haven't seen any dyno sheets on this dx yet.

by **4agtepwr** » Wed Jul 02, 2008 1:42 am

Mines stock internals, No fancy rods and just toyota ze pistons, Be really keen to see a dyno plot and learn a little more about the engine for sure, be keen to see a plot of the boost curve as well because mines fairly laggy with GT3071r and that had supposedly a GT3582r which is a fair bit bigger. Very well done though. Will have to lean on mine a bit harder now, If I could get a decent intercooler in there it would bring it up bit, then theres always C16 :twisted:

That is what a lot of guys are using, stock internals, good H/G and head job then a lotta boost.

Who can tell me a bit about using nos, id like to run it on my car :lol:

by **IH8TEC** » Wed Jul 02, 2008 6:26 pm

talk to kent as he uses nitrous on just about all the cars he builds.

with the wagon, he can rev it out to 10,000rpm which helps him a bit with the big turbo.

by **Diesel PWR** » Wed Jul 02, 2008 8:17 pm

10 grand, now i really want to see a dyno plot, box of beers to the first one to post a legitimate print out.

by **4agtepwr** » Wed Jul 02, 2008 8:36 pm

10 grand aye, thats pretty impressve stuff, Need some pretty serious head work and giant cams to be still making power up that high and id stay oversize buckets to be able to take a cam with that much lift, Just beacuse and engine will rev that hard dosn't mean it will make power anywere near that, Be keen to know about the oil pump and such as well. Does anybody know the guy who owns that red dx, would really like to chat to him and swap ideas. I presume the nitrous is just there to help spool the turbo???
