How much torque comes out of a turbo D-series

[micky_d01]

Hey everyone,

EVERYONE MAKE A POST HERE!! :)

I invite anyone (or ppl who know of a friend's set-up) with any model d-series (d15, d16, vtec, non-vtec, anything) that has been dynoed with any amount of boost (3PSI, 10PSI, 20PSI, anything) to post some figures of the max torque that they have pushed out of their boosted D-series. I'm curious to see what other people have pushed.

Let us all know descriptions of the
* Car model (and whos car it is if it's not yours)
* Engine model
* Breif description of turbo setup
* The torque it put out (the power that it made too if you like)
* Anything else you would like to add. Dyno graphs would be nice.

Thanks,
Michael.

* Car model 92-95 Honda Civic Hatchback
* Engine model D16Y1 SOHC VTec
* Breif description of turbo setup GReddy Turbo kit with added intercooler and injectors
* Torque it put out 205Nm (Very brief though)
* Power 137kw at 11-12psi till she blew up = Con rod throw the block
* Dyno graphs would be nice.

Thanks Lukezen. That's pretty good power. Dam, too bad about the rod through the block! Are you going to repair and go again?

Keep the figures coming please :) What has everyone else got?

All the D's go pop in the end mate

Most people don't get those high numbers man so don't expect the same...
110-120kw is the normal power

I've got a EG5 B16A SiR II on Boost now that powns my old setup

[VTECnique]

I have always been taught, for a stock block D, going past 200whp runs risks. Looking at Lukezen's dyno, 137kw equates to only 184whp.

Yeah on that run but the 160kw run on the dyno is when she blew hahah

[VTECnique]

which equates to 214.4whp...

[Lukezen27]

which equates to 214.4whp...

correct

My point is any little thing that goes wrong on a boosted D = blown motor

[VTECnique]

With your above mentioned power output, that would have put you in the danger zone, but the 137kw output was well within the range...

Of course with any stock block turbo setup, take it past the safe power zone range, & of course any little mishap will make motor go bang!

Mate your missing the point

I didn't mean to go to 160kw it was problem with the boost controller

HENCE my statement

""My point is any little thing that goes wrong on a boosted D = blown motor ""

A B would handle an over boost of 4psi

[VTECnique]

so you got boost spike? internal or external wastegate?

[Lukezen27]

internal with an EBC

[VTECnique]

A B would handle an over boost of 4psi

This would all depend on what power range your in with a B-series. Yes i do realise the B's can put out alot, but if your running it near the danger zone, imo the same thing would happen if you got a boost spike of 4psi...

[VTECnique]

There's alot of guys that have boost spike with internally gated turbo's.

I'm not so sure all D's go pop.

Would anyone else like to add their figures?

[Lukezen27]

Even the built ones seem to go pop here in OZ

There are a few going round that are wicked but the guiys really new what they were doing when they built them.

I blew a HG first on only 7psi on a motor that had only done 96,000km

Fixed that but the bottom poped about a 1.5 years after that

[VTECnique]

At first, at least you only blew a HG, alot of the turbo guys strongly suggest to use ARP head studs, much stronger than OEM head studs. But i have also heard alot of them running stock head studs on +10psi...

[myztery]

For me:
* Car model 92-95 Honda Civic Hatchback
* Engine model D16Y8 SOHC VTec
* full built motor, only stadard thing left was crankshaft and camshaft
* Torque i cant remember
* Power 152kws at 11.5psi

[micky_d01]

Thanks myztery. That's an awesome result from 11.5PSI. I'd be heaps happy with that.

How does it run? What standard car would you compare it to now in terms of acceleration?

myztery is on his second or third block though so hope you got deep pockets :p

That's why he's only running 11psi on a built motor

[lookingforboost]

hmmm boosted D nothing wrong with a boosted D :)

Seriously man, you give too little credit to D motors.

I know you've had a bad experience, but any engine would blow if you took it too far - Bs or Ds. Obviously Bs are stronger than Ds, but a well built D can last a lifetime. I'll be running 12PSI on an engine that I built myself and I don't expect it to ever blow while I'm still driving it. :)

[micky_d01]

So yeah myztery, how does your car compare?

Everyone else, please feel free to post your figures.

Don't get me wrong bro as I loved my boosted D :thumbsup:

I drive her hard and fast every day for years!

I was planning to build just before she blew but decided got go the DOHC VTec to leave me room to build for big numbers down the track if I want or just safe PSI on a stock motor.

Unfortunately I went to WSID on very hot days and did some damage I believe,. she blew on the dyno the following weekend.

I now understand why close to one else turned up that day lol

The main problem with boosted SOHC VTec is the power brand and lack of constant
torque.

You need really big numbers to get good times

SOHC VTec D16Y1 11psi 137kw
14.55 2.4 60 footer 99MPH 205 Torque but only stays there ever so briefly

DOHC VTec B16A 6psi 136kw
14.1 104MPR

DOHC VTec B16A 8psi 151kw
13.6 2.3 60 footer 107MPH 205 Torque but stays there till red line

[myztery]

a mate from bel garage took it out for a drive and said it drove exactly like his 20 valve turbo he built, which i was very honored to hear...

for luken27 its my second motor...
first motor was built wrong, which is a trial and error that you learnt as well, you gave up on the d'z where i wanted to solve the problem

Didn't give up man!

Just moved on to a better platform base.

[micky_d01]

More torque figures please :)

[Lukezen27]

More torque figures please :)

Yeah I want'a see em too :thumbsup:

[fat_85_civic]

ill post mine up on the weekend after i get tuned on Friday!

[ralph_ef9]

any power and torque difference between boosted dohc d16/zc or sohc d16?

[Lukezen27]

Yes the ZC kills the SOHC on torque

Best D every for boost hands down

[VTECnique]

I wouldnt say better, just easier to extract power. Building a boosted D is much better cause its more of a challenge...


myztery is on his second or third block though so hope you got deep pockets :p

That's why he's only running 11psi on a built motor

D16 blocks are everywhere bud, cheap as bloody chips. i could pick up a block & head & g/box for about the same price as just a B16A g/box...

Alot of people seem to underestimate the Ds. Extracting power is alot harder, but once you've mastered the skill, the D is truely a nice little single cam engine...

i totally agree with that once you get it to open right then the rest is up to the tune.. im not saying iv mastered it but hey its almost there just gotta know not to push it too much lol...

Come race me at The Creek bro :p

Luke vs Luke


I love it.


Old school loving just incase Luke forgot.


Heres the graph of when it was completely stock

And here is the graph after tuning on friday

Come race me at The Creek bro :p

will do when finished no drag experience yet so give me a some prac first....:D Mr BIG shot

[Lukezen27]

lol I've only been about 10 times man ;)

Its heaps hard lol

You hvae to say at 150kw though

lol Lloyd

He's running a DOHC None VTec yeah?

[fat_85_civic]

yup, D16A3, same as 1sr gen integras

[Lukezen27]

yup, D16A3, same as 1sr gen integras

Yeah will that's a much better starting point than the SOHC VTec anyway..

Your only makeing 5kw more than my last SOHC VTec at the exact some PSI 11...

But being DOHC it should kill in drag times :thumbsup:

My B16A on low boost 6psi makes 137kw the same as my last setup but its over half a second quicker on the 1/4 mile
