why its a good idea to turbo charge.

[jimmeh]

i found this article in import tuner dec 1999
i thought it would be interesting to sho you guys exactly what power gains u get when strapping on a turbo kit. the kit used was a Drag Gen 3 turbo kit
enjoy

Interesting read. Plus PQ points for you.

Yup good read. I do doubt the last statement about a N/A B16 motor never seeing 250 hp at the wheels. I have seen it. Of course it was modded big time, no nitrous too. But it almost cost more than $4k USD. I think after the tuning and dyno time we used it was at like $5k USD. I'll see if I can find the dyno print outs and info.

[LowEk]

that final figure of 283.7 hp would be at the fly?? i was talking to someone and i said that people in the US are making 250-300hp in stock B16a turbo's and they said its a bit far fetched like everyone in the US there dyno's are all out to ours here in Australia and make far fetched figures on the dyno. i have seen dyno sheets to prove this power being made and people just dont belive me these are people on H-T posting what they have done to there cars and also posting dyno graphs. some of these power figures people say that they are only using US pump fuel which i think is 93ron but dont quote me on that. elighten me people. :)

despite the extra power it adds it adds alot of weight doesnt it???

nah not really man.

lol
a turbo kit weighs around the 30lb mark. - stock exhaust, u will gain around 25lbs.

Colorado has 91 oct for high end street gas, Texas has 97 oct, California has 93, I've seen some up to 99. We raced with 120ish oct.

[saxman]

it's rare to see anything over 91 in california


you have to realize that the octane rating here usually isn't the same as everywhere else.

In Australia, fuel is listed on the RON scale... in the US, we use an average between the RON and MON scale, which results in an octane value about 5 points lower... i.e. our 91 octane, which is the best stuff I can get at the pump, and use in my turbo honda, is about equivalent to a 96 ron over there.

[LowEk]

yeh well we can get 98ron from a pump here its either BP Ultimate or Shell Optimax otherwise premium ulp is 95ron.

[tinkerbell]

their (USA) octane is MON

it is much different rating to our RON...

[saxman]

their (USA) octane is MON

we use the average of mon and ron


(MON+RON)/2 if you may

[tinkerbell]

sorry, my error, what is the 'name' of the (MON + RON)/2 concept, if it has one?

[saxman]

sorry, my error, what is the 'name' of the (MON + RON)/2 concept, if it has one?
I believe the technical name is "the US goverment is retarted"

unofficially, there are a few names, mainly the Anti-Knock Index (AKI), Road Octane Number (RdON), and Pump Octane Number (PON)

[LowEk]

anyway getting back to my question bout hp figures anyone got any answers for that??

[tinkerbell]

um, read the article dude,

it says it is tested ona DynoJet dyno - which is a "chassis dyno", not an "engine dyno"...

[LowEk]

i have read it and the power figure of 250whp is very good but i have spoke to some people and they say thats its far fetched and you would be lucky to make that figure here in Oz. i really think thats its not that hard to get as long as you have the right setup of turbo and is tuned well i dont think you should have any problems getting that figure.

[tinkerbell]

you should not be looking only at the WHP *figure* you should be looking at the *gain*

as a %

170 to 250 = ~32% increase...

doesnt sound so far fetched not does it?


just for comparison - my ATW figure went from 90kW to 120kW with a normally aspirated B20VTEC = 25% increase...

[Felix]

nice..

yeh i spose thats not too bad actually.

[tinkerbell]

no, no, no!

my point is not that i made 25%

teh point to draw from my simple comparison would actually be that dollar for dollar - turbocharging gives a greater % gain in performance...

25% is a huge increase for Normally Aspirated, and i had to change the whole engine to do so!

people with DC2 Type R that are already putting out 100kW stock, struggle to gain 10-15kW with bolt-on mods...

many never achieve 25% increase unless they rebuild the internals and go with bigger cams and rebuilt head...

to see the easy 30%+ increase a turbo kit provides, a DC2R owner would probably have to get quad thrtottle bodies as well - increasing the expense 3-4 times over a turbo kit...

[LowEk]

yeh i spose so.

[saxman]

a 30% increase in power is very minimal to be honest... you should be able to make WAY more than that...

I increased my hp by 68% and torque by 79% with a simple turbo set up(on a d16z6), for about the cost of a mediocre i/h/e set up...

increased hp 56% on a simple turbo set up I did on a b16a a little while back, etc... all with nothing too crazy

[tinkerbell]

170 to 250 = ~32% increase...

from 90kW to 120kW = 25% increase...

sorry, i have just been corrected on my math, LOL!

170 to 250 = 47% increase

170 to 283 = 66% increase

90 to 120 = 33% increase

very sorry to mislead anyone... :eek:

EDIT - two errors in one thread :confused:

must be gettin old tinkerbell ;)
i dare say i easily doubled my power with my turbo setup!

[Weq]

we use the average of mon and ron


(MON+RON)/2 if you may

Also US fuel is laced with ethonal. its not the same quality.

[saxman]

Also US fuel is laced with ethonal. its not the same quality.
not necessarily... they add small amounts of ethonal at varying times throughout the year, and depending on geographic location, etc(more populated areas get it longer)

[vtec_king]

lol , turbo in hondas ? um.... just wondering if u put a turbon on, would it affect da performance of vtec ?

[Q_ball]

lol , turbo in hondas ? um.... just wondering if u put a turbon on, would it affect da performance of vtec ?
obviously not, if it did have negative impacts on power, then we wouldnt have such good results with vtec turbos

[superR]

is it true there is a 15% difference in horsepower between aussie hp readouts and U.S hp readouts...... i have been told this before by a friend of mine.

james

[saxman]

lol , turbo in hondas ? um.... just wondering if u put a turbon on, would it affect da performance of vtec ?
VTEC = little performance difference


turbo = huge performance difference

so, yes it affects the performance of vtec a lot... you stop carrying about the barely noticable boost in power(if at all) of vtec, because your car actually has some power from the turbo

[shebangs]

I think the point of the article is purely bang for bang. Bolt on $6k-$8k turbo kit, and the increase will be alot more than putting that same $8k NA.
