You remember what RPM that 10.9 was at? Mine at 6000 rpms was the exact same number and she runs great I did have it dyno tuned again because I had trouble with cold starts...now she is about 11.1-11.3 at 6000 rpms and I increased RWHP to 465 from 454! The tunecan make all the difference (even with small changes) and your car and its new whipped baby are running great!!!!!!![sm=exactly.gif][sm=happybounce.gif][sm=icon_ladiesman.gif] Congrats! J

I was at 10.9 all the way from about 4000 to about 6200 when I lifted.

Some more thoughts per my above post just thinking out loud.

The more I think about this and after seeing thelink Moosestang posted with a dyno of a Whipple making 470rwhp Ithink it would notbe that hard to tune our own cars using an X cal and a wideband and get 450rwhp or morewithout even getting a dyno tune. I know sounds kind of crazy but I think this could be very possible.


The reason:

I have been doing a lot of research on tunes and tuning (wanted to take EFI tuning classes to be honest) lately. I have also researched the Saleen S/C and JDM's tunes ( who imo do excellant work & tuning) to look at thier tuning and see what they are running as far as psi,rwhp & rwtq vs. timing and afr. (For the record I have tuned onmy lastS/C car with wideband afr regarding timing and afrin the past so I know a little.)

Looking at their timing:

Their setups/tunes seem to range from 16* of timing (450rwhp) 17* timing (470rwhp) 18*(490rwhp) at 13psi, but the thing to look at here is the timing. They range from 16*-18*.

Looking at their AFR:

JDM likes to run 11.8-12.0 it seems.


The Whipple stock tune timing 19*

So as we see above the Whipple H.O has very good timing already tuned into it to make high rwhp looks to me like that doesn't even have to be touched. Now if it ran 16* in the stock HO tune then this would be another story and another parameter we would have to set but its not the case.


We have also seen Whipples (stock tune per dyno sheet per mosses link) make 460-470rwhp 19*-? And also seen them make 410rwhp running 19* timing as Mossestang did some data logging (18.5*@6.2k) to back this up. So to me the timing is set for high rwhp no doubt.

I believe the timing is set but would need to check one more thing to be 100% sure. Timing can be set at -0-2000 (low end) 2K-4k (mid range) 4k-8k(up top). During these ranges you add or minus timing as you want or needed per tune per rwhp & AFR.

The one thing I would need to check is if I had a data log file of a second gear pull (1k-6.2K) from the stock Whipple tune (like Mooses car) anda second gear pull (data log file)from a custom dyno tune say mygt500 car which by the way can be e-mailed to me to look at.

This way I could look at the timing though out the rpm band andin the three ranges my bet is they are not going to be that far off due to the Whipples high rwhp dyno sheet I seen.

I think Whipple went more conservative on their tunes lately by just throwing fuel at it and they left the timing alone!

So if I am correct a Whipple stock tune that has a dyno of 410rwhp running a 10.8-11.0 afr. One could very easy tune there motor to produce around 450rwhp or more using an X Cal 2 and a wideband themselves if you how to set/adjust the parameters using a X cal2. Just start with 1-2&of fuel at a time make second pull’s one at a time and use the AFR to dial it in to a 11.5-11.7 afr. I could get it done in 3-4 pulls from my past experience

I think you would have around 450rwhp or more.

The Whipple tune is all set all it needs is fuel!!!!!!!

The above is just my opinion I could be completely wrong and don’t try this!

I would have no problem being very careful and trying it myself (but also confiming with a tuner first on the above) then get a dyno & check the parameters.

The only catch is we need to be able to get the Whipple tune loaded on an X Cal 2 if that is possible.

Hey Guys,
@6000rpm my AF is at 11.7-12 and that is what my Tuner said it should be.If under WOT it goes up to get off the gass becauseI might have a problem. As for driving around it will go up and down in the higher range normally.Also he set the knock sensors at 2 instead of 4 as he said that would be better for them and the car.
The car had 479 STD rwhp and corrected was 467.23 SAE
I don't know the timing off hand but will find out.

As for the Canned Whipple tune, It is crazy that I have seen some cars with 487 hp or high 460hp and others even like mine producing 409-420 with the box tune.

Either way after being showed the AF readings anf fuel curve along with the fuel injectors flow % that i am running a very smooth tune through the whole power band. Now I will say that my tuner James at RWTD suggested that in the future that if I go bigger on anything on the motor that can increase HP that Bigger injectors wouldn't be a bad Idea but for my car now they are fine.

As soon as My wife gets home tonight from vacation, I will have her upload my dyno Graphs and Video for me. I am not a computer wiz like most of you guys and am sitting here going nuts trying to find a way to upload my videos to e mail, I can't send 16 MB through my e mail and trying to upload to photobucket is not easy for a computer illitteret like myself.

PS, Nails If you need to speak with my tuner, PM me and I will try and put you in touch with James at RWTD.

Thanks Tassy. I was planning on going to 454 dyno in Covington, but a few people have recommended Stang-hi in Baton Rouge. 454 dyno has decades of experience, but Cody at Stang-hi strictly tunes mustangs, so he's got more experience with the S197. I haven't decided where I'll be going yet, but it will be soon.

Check my post here for my thoughts on why whipple HO run rich

And I dyno'd 416rwhp w/ 11.5-11.8 AFR with an 8psi pulley SAE Corrected on an 80 degree day. Stock whipple Tune.

This is in response to my post #25 regarding the below.

I talked to a tuner and it is possible to get the FRPP tune on a X Cal 2 but depends on the year and calibration code onthe car for him, so I sent him my code and he will let me know if possible on my car.

So if I go Whipple I will be go this route for a number of reasons as somewhich I posted already as I already have an X Cal2.

When I get more info will post it of course I don't know how much but figure the cost of a mail order tune would be my guess.

Edited I think we might not be talking about the same thing if you read this post.

I stumbled upon this old thread and thought 9inchnails would like to see how paranoid he was when he first installed his blower.

I have the whipple tune, vmp tune and brenspeed tune and all three have a 14.4 afr at idle and cruise for the most part. The brenspeed tune will hit 16:1 at tip in(part throttle), which is a little unnerving.

I've datalogged timing for each and whipple is 18.5-19.5, brenspeeds will hit 20 before redline and the vmp tune has hit 22-23 degrees at wot, not at redline though. it should be no surprise that the vmp tune feels like it makes the most power.

AFR at wot

whipple=10.2, no that's not a typo
brenspeed= 11.4-11.7
vmptuning= 11.7-12.0

Guess Whipple likes to go ultra conservative with their tunes . . .

Do they have a warranty or something they're protecting?
