and another one. anyone know what the CFM and max PSI our turbo's are rated at and what CFM/PSI would be needed for 500-700BHP? :rofl: only asking at the mo. cheers folks in advance.

si.

the stock tb 22/02 is rated at 304 cfm - not too sure what the maximum psi is but there just isnt any point running them above 14psi becaus ethey generate more heat than anything else

 

the rest is purely speculation because everyone will have their own opinions

to get 500 hp you need to be running somthing like the following turbos supported by appropriate engine mods

 

Mitsubishi TD05-16G 520 cfm

HKS GT25-30 477 cfm

JWT 600 - aprox 500 cfm

PE 14-20 - 494 cfm

 

to be running 700 hp i would think you need something like

MItsubishi TD05-18G aprox 600-cfm

mitsubishi TD06-20G 685 cfm

PE 18-20 635 cfm

Garrett GT-2835 608 cfm

 

hope this help

cheers for that mate. only thing is, i aint looking at turbo's ;o))))

i dont think you'll reach 400 hp on stock turbos mate :confused:

what i was thinking of was doing away with the complexity and how awkward things are to get to and fit one of these:

 

VORTECH V-7 YSi-TRIM SUPERCHARGER

"Large blower" performance in a smaller package that fits most existing Vortech bracketry

 

 

Fits engines up to 1200 horsepower

Maximum airflow: 1,600 CFM *

Maximum boost pressure: 30 PSI *

Maximum impeller speed: 65,000 RPM

Adiabatic efficiency: 78% **

Available with straight or curved discharge in clockwise rotation only

Click here for YSi-Trim models

 

 

copied from their site.

there are loads of supers that will easily generate big power and since its one unit, has no exhaust gubbins to worry about and can sit where i can get to it, i think it'll be worth the time/effort to fit and set up. the only problem i have is that im not really up on this CFM rate, etc.

i did notice that supers are more expensive than turbo's but since i only need one, that works out pretty much even.

also, i noticed a thread on here a while ago where some were saying that the exhaust manifold limits ultimate output, another that you have to mess with the inner wing to get big turbo's in, etc etc.

i know it aint going to be easy to charge it but in the long run i think it'll be worth it.

do you know what the ideal PSI, CFM, etc will be? im after 800+bhp (i know its a long shot) but anything over 500 would be enough at the mo. cheers

si.

feckin hell - good luck to you - i know nothing about that at all :D

 

i suppose to get 500 hp at the wheels you're going to need about 1000 cfm but thats just a guess - unless you are going to run forged internals you cant really run anything above 1 bar

im after (as money allows - i'll be having a spare engine lying about soon) JE low comp jobs, carillo/eagle/etc rods, IF i can get a reasonably priced one, a stroker crank but most likely i'll have mine lightened, peened and treated, one off or seriously strong bottom end bearings, bolts, etc, stronger more flow oil and water pumps, block de-burring (TTZ recon this is a prob in the waterways on highly tuned Z's), metal headgaskets, heavily worked heads with strength in mind, bigger valves, stronger springs, higher lift same duration cams (going for torque), one off intake manifold with single inlet side from charger, 2sets of injectors - 1 stock sized, the other 550's, massive FMIC (maybe 2 if they can locate angled from middle to side) im going to ask the lord (john dixon) if he can map all this in for me then its all the annoying little bits that you always forget you'll need (brackets, etc) that'll take time and money up. im looking at about an 18-month- 2yr build if im doing the maths right.

i have no idea what power all that'll be worth but i've had guesses anywhere from 500bhp@wheels (me) to "at least 1000bhp" (a mate that thinks his RX-7 makes 600bhp)

what do you all think?

si

oh, and that super is rated at 1600CFM and 30PSI. there are some that will do a lot more than that. the good thing with supers is i dont have to bother about lag. they dont have it so i can just get the biggest one my pocket and the internals will allow.

any guesses?

lol

si.

dont hink anyone has done it before so you'll just have to make best guess and take the plunge - a fully forged engine should hold 2 bar ok so on that asumption the compressor you've looked at would seem about right for 500-700 horses - depending on the losses due to driving the compressor

cheers mate. i know its a new thing but hopefully if it works out ok it may catch on. we shall see.

si

Seek out the articles from the US circa late 80's / early 90's that had JUN :bow: engined Zeds running 250+mph at bonneville, you may save a lot of time and heartache bro............

 

I think i have them somewhere to scan and post but its a trip to the loft me-thinks
