Went to the dyno to do some tuning with the apexi and see what the steves auto clinic head and schrick cam did for my car, I was surprised and IMPRESSED! I knew it was running better than ever and felt like it hauled *** !

last time at the dyno we got 176.8

this time the first pull was

202.3/164.2

I was shocked because I really didnt expect more than 190 - 195

Then El Diablito did some tweaking to the apexi and we got a best pull ( last pull at that ) of

209.0/170.8

YEAH !!! THATS WHAT I'M TALKING ABOUT !!

There is still romm for some improvement and I have a couple other things to do before I go back to the dyno.

Just thought I would share my happy #'s.

El Diablito is the MAN !

 

Very nice indeed. You've broken into the 200whp club. Hope I'm there soon.

Michael

 

BOOOOOOOOH YA is wright! 209/170.8 nice.

 

Just one question, are you running an LSD?

 

nope no lsd, that is on the list once I save some $$

 

how would the lsd effect the dyno numbers....or is it just a unrelated question???..thanks

 

Is it a secret or will you list your Mod's?

 

hmm I tried to post this a min ago and it didnt show up.

My mods are

Head from steves auto clinic
Schrck cam
throttle body
header
cat back
15% pulley
ported intake
alta intake
APEXI ( and DYNO tuning )

I have a few more things to do before I am done. More to come in the next couple weeks.

 

Very impressive! I talked to El before and after he dyno tuned your A'PEXi. I'm going up to DRS later in the month to do the same...though without nearly the mods you have. Any plans to get some 1/4 mile times?

 

I doubt I will get any 1/4 times, the car isnt really a 1/4 car. No doubt I would like to do a couple passes just to see but I would rather go to a road track instead.

Good luck with the tuning, El Kicked *** tuning my car.

 

When you say " ported intake " are you refering to the snoots (jlm) , air horns (others),I.E. supercharger output duct and Intercooler output duct?

 

just for the record.............


I "butt dyno'd " the car at Steve's on Sunday.... (rough tune by feel)

that laid down the 202whp first run

2 tweaks later and 209whp...... with a few ponies still sitting in reserve


first car I have seen lay down over 205whp with STOCK injectors....

 

Psssh....and you thought you were gonna have trouble at the mini challenge....look at those numbers

very well done detlman....and of course, props to el diablito

 

great numbers, I'm curious what your baseline torque was. Did the cam keep the torque curve flat or is it significantly peaky? I'm thinking of doing the head and cam next. How does it pull now?

 

Great job EL

Glad to see that you have become proficient with the APEXi S-AFC.

So....is your "butt dyno" SAE or Uncorrected?

 

SAE.... it's been "certified" by NASA

 

detlman --

Let me ask a question about the HP numbers we are talking about here.

I am familiar with brake horsepower (BHP - measured at the flywheel) and wheel horsepower (WHP - measured at the drive wheels). Typically, dynomometers will report WHP and use a conversion factor for BHP.

Because of the mechanical linkages between the flywheel and the front wheels, a certain percentage of "driveline loss" causes the WHP numbers to be lower than BHP numbers. Randy Webb of Webb motorsports has consistently seen MINI driveline loss to be in the 11-12% range.

Thus, converting WHP (what a dyno actually reads) to BHP can be calculated by multiplying WHP by 1.12; 100 WHP equals 112 BHP. With WHP at 209, and using our 1.12 conversion factor, we arrive at a 234.04 BHP.

Remember, MINI rates the stock '04 MCS at 163 BHP not WHP. To convert to WHP we have to multiply the BHP by the reciprocal of our driveline loss factor (0.88); thus, 163 BHP equals 143.4 WHP.

So do I understand correctly that you managed to increase WHP by 65.6 HP using your mods? That's a 40% increase over stock.

What is the manufacturer of the dynomometer you are using? Did you cool the intercooler air with dry ice? Do you have dyno plots you can post? Please share the details with us!

Thanks!

Welcome to the Vette killing club!

 

Actually you need to divide the whp by .88. 112bhp equals 98.56 whp and 100 whp equals 113.64 bhp. Its only a small difference, but the math is wrong and will be worse with bigger numbers.

bhp*.88 = whp
whp/.88 = bhp
( this is for a 12% loss)

 

The ported intake is the actuall manifold that is bolted to the head, it was port matched.

I have not touched the intercooler inlet or outlet manifolds.

 

I have a feeling I will still be working pretty hard to keep the pace since its all driver and I am still in learning mode. I cant wait for sunday. I hope you all dont expect too much of me :-)

 

No ice or any of that , a little water sprayed on the intercooler between runs but thats it.

I think for the most part you have the #'s right ( or close enough for me )

The dyno was a dynojet, I will have the plots but they put them on a floppy disk and I have no floppy drives so I am waiting for one of the other people who was there to email them to me. I will post them as soon as I get them.

 

here are the 3 plots, I dont have a scanner so I clicked a couple pictures. They might not be that good because a couple marguritas are affecting my focus


1st pull showing 202 and 204

Plot showing the last time we dynoed the car and the best pull from this time.

I left the pictures full resolution and size so you can take a good look and see there is no photo shop or any sillyness, you can also look at the a/f and see how clean and smooth it was compared to the original run.

56K beware !

 

But wait, I was there! Saw the magic with my own two eyes. The little black beast is a screamer. Every time El messed with the Apexi the numbers went up! All in all, fun day even if I had the most anemic car there at 185 whp.

 

Detlman, there's going to be some serious dyno envy on NAM, starting with me!

That is a great looking sheet, good a/f's and all. It appears that the key to your success in making your improvements perform in harmony is the Apexi and the time spent dyno tuning. Comments?

Congrats to you and Diablo for a great job. Maybe when my JCW is out of warranty...
