rev1/2 turbo power figures........220, really??

[jimGTS]

has ANYONE with a standard rev1/2 been on a dyno and actually reached the 220bhp that everyone claims these have???????
as i havent heard of a single car that has???
i here anything between 190-210bhp
the american turbo cars are 200 standard, and jdm are ment to be 220, but ive never known a rev1/2 as yet to get near that 220 figure, closer to 200 yes.

is this purely down to the age of the car?? wear and tear and all that?
or do secretly, jdm cars do actually only have 200 like the usa ones??
rev3s stil seem to be pulling 240.

Mine was 211bhp when standard with mongoose exhaust and Apexi filter. 220bhp is running on Jap 100 ron fuel.....

Now is 262bhp

[Al-sw20]

Has anyone taken their engine out lately and put it on an engine dyno?

Thats the only sure way to tell.

[jimGTS]

Mine was 211bhp when standard with mongoose exhaust and Apexi filter. 220bhp is running on Jap 100 ron fuel.....

Now is 262bhp

so with exhaust and filter thats got to be at least 10bhp.
so 200 standard.


im sure 2 extra ron points does not make up 20bhp!

by the way mate, when you fitted a downpipe, what effect did that have on the car???
how much bhp increase do you reckon you got?

of course not. it will be down to engine wear aswell, and mine is a healthy engine, previously owned by IMOC's Steve Harrison, cheers Steve your old engine is doing me proud

Fitting a downpipe, made the car feel quicker and increased turbo spool up. Would have to get it RR'd to find out bhp Increase. saved about 15KGs in weight too!

dont get me wrong, i never said it was crap or anything, far from it, lol!
im just saying, its just more proof that these rev1/2s arnt that close to 220 standard. more like 200.

so is your 262 before you fitted the downpipe then???
or are you telling me to get it RRed before and after???
before 240, 244 torque

[craig]

Wasn't having a pop mate! These rev 1/2 turbo engines yielded 220bhp in Japan when built.

13-15 years later, a power drop of some kind is expected. You are probably right in saying that the rev 1/2's are closer to 200 bhp than 220. As I say, mine standard with mongoose and Apexi was 211 bhp!

Cheers

[paul_h]

about 2 yrs ago paul had his on the dyno running in safe mode. i.e low boost due to clsed vsv.

His put our 205bhp so with another 3 psi i reckon it would have easliy seen 220hp.

Bet they would! I've been told by my mapper if i get the second map in my motec set up for 102ron race fuel i could expect to get another 50-60bhp. Thats going up from 97ron sul.

[Quigonjay]

from what i've seen on various boards over the years it seems that MrT slightly overestimated the power of the gen1 tubby engine yet slightly underestimated the power of the gen2 tubby engine. Like you say Jim, i also have never seen a standard gen1 tubby make 220bhp, but have seen standard gen2's make more than the 245 quoted.

No problem I'm glad to see it still going strong, although it kinda makes me wish i'd stuck with it as now i've STILL got no money to mod my rev 3 engine, ah well

Are you planning to go big power with your engine? And I assume your glad with the decision of an engine swap?

Hi mate,

I've run out of money to mod it now. Got 262 bhp so far. Wouldn't mind around 300-350...

need a lot of funds for that tho, so we'll see. Glad I had the engine swapped. Best move I did!!! Well chuffed.

Take it easy mate,

Cheers.

from what i've seen on various boards over the years it seems that MrT slightly overestimated the power of the gen1 tubby engine yet slightly underestimated the power of the gen2 tubby engine. Like you say Jim, i also have never seen a standard gen1 tubby make 220bhp, but have seen standard gen2's make more than the 245 quoted.

They are exactly the same motor. The only real difference is the inlet of the 92+ 3sgtes.

I think he meant the gen2 and gen3 engines?

Wasn't the gen1 engine only fitted to the old st165 celica's??

[jimGTS]

yes sure you we only ever know true bhp with the engines out, but the losses are generally 18-22%.
whp on american cars its 160-165wbhp, which is ment to be 200bhp.

now im not saying back in the release of the turbo when new on 100ron it wasnt pulling 220 in japan, i cant be sure of this.

but everyone standard turbo (rev1/2) seems to be pulling 160-165hp at the wheels, which is not 220, more around 200 like the usa folk.
speedo tech, what was the wheel hp tho??

just my 2p folks.

i was talking about the GEN1 engine in rev1/2's and gen2 engines in rev3+

[twistywizard]

When I first had the car standard it made 216bhp but as said before these are ALL guestimates!

Due to running on less rated fuel and age I think will drop 20bhp easily.

Although mine aint standard anymore so makes no odds

The rev1/2 engine is the gen2 3sgte and the rev3+ has the gen3 3sgte. The early ones as fitted to the st165 celica was the gen1 with only 200hp.
