come on then folks, guy i know swears blind his car is 327bhp and 400ftlb, using the standard engine blcok, rods and pistons from his uk turbo.

any idea if you could actually get up that far torque wise?

personally i would have expected it to be much higher bhp to get near 400ftlb and there fore spit a rod

 

I dont think the question is how t get there, but how long it will last

 

not long lol, but how could you even get that high?

 

what boost pressure, would assume high to get the torque up.


has it gone bang yet?

 

327 and 400lb ft?? Interesting! Generally peak torque falls around or behind peak bhp with rice rocket turbos doesn't it?

I thought that if you wanted to preserve engine internals you'd run more bhp than torque, as to get the big torque, don't you need big boost pressure?................. I fear my ignorance may be showing

If he does have 400lbs on std internals, I reckon it's a matter of time.......

Ns04

 

can i just say i totally agree with it going pop, i'm not even sure if his info is correct, hence askign what you'd need to do to it to get that much torque

 

must be possible as theres a guy from my village with 700 bhp from a 93 wrx with a standard 16g and 380cc injectors

 

yeha but i bet hes running 3 turbonators in paralel

 

He could well be reading his graphs wrong.

 

400 Nm anyone?

 

that was one of my first thoughts. but he def said 400ftlb

just gone to a conversion program and it comes out to 295fltb, which sounds roughly about ball park, so i'm gonna take a stab that thats correct

 

no but he has 2 dump valves just one of those idiots life throws at you thats not worth arguing with

 

not realy arguing tbh, just more curiosity, although it did kill the cat lol

 

Might I suggest that the engine builders form an orderly queue to offer their services.
Although I reckon his reading must be in N/M

 

My Newage WRX put's out 320bhp and 405 nm at 1.25 bar on standard reckon the guy's got his ft lbs and nm mixed up !!

 

20g turbo, 550cc injectors, walbro fuel pump, tublar headers, 3inch turbo back exhaust, aftermarket remaped ecu, you would need a uprated clutch of some sort otherwise it would slip very badly

 

You can just visualise that grenade going off under the bonnet !!

 

I had 406 BHP at 1.6 bar out of my MY00 UK turbo on its original unopened engine with original clutch, original manifold ported, original ECU remapped, but it didn't hit 400 lbft, it was only 363 lbft IIRC. I used about 1.8 bar in the midrange and silly doses of octane booster with a 20G, FMIC, uppipe, exhaust, 550cc injectors at raised pressure, Walbro etc. Surprisingly it didn't break, but I already had a forged engine ordered to go it assuming it would. Stupidly I pulled out the original working engine and had three non-working forged engines in a row.

No wonder I still maintain a really healthy respect for factory engines, although 400 lbft is crazy.

 

Sad techie biased reply....

10" wheels off a mini should up the torque to that sort of figure...

DunxC

I know I'm being silly, did it to my Imp in the 80's boy did it pull, went back to 13" wheels on Yokohamas very quickly tho'

 

327bhp and 400ftlb, if the bhp was higher it maybe possible but the bhp v ftlb figures look wrong from what I have seen on other cars and rolling road charts. As said by all of the others that would be a large stress on the engine at that level boost and would reduce the life of the engine quickly.

Maybe get your mate to show the rolling road graph.

 

Hope he is not running his standard gearbox on that as anything over 340 bhp and similar torque as I am sure I heard somewhere that anything over this would break 3rd gear or am I wrong, If I am wrong There is no need to change my gearbox to reach the magic 400 bhp as this is the next big cost of reaching this goal.

 

No gurantee that the box will break at 340, in fact as discussed else where if you have a STi box then there is every chance it will work even when you go for 400. I think that 911 has a STi box with a 20G and I have one with an 18G so dont rush out and change it until it does break.

 

mine did break at 260bhp and 280 ftlb lol

 

dont worry i figured it out for ya, he must have one of those turbonators!

 

been lurking awhile just viewing other turbo ideas and this thread surprised me that you can't get the levels quoted on standard internals. Can it not be done and maintained even with non standard turbos?
Its relatively easily done, and still with factory internals on my pipe n slippers car .....................

kontrollfreak

 

my std internals have done that at least for the last 18 months.

so much for chocolate pistons eh?


... will probably explode tomorrow now
