guess my numbers

[Bradley G]

My car should be on the dyno tomorrow morning after we take care of the intake changes, a new maf , an open element filter and the fuel pressure sensitive to boost.
And of course swap the stock 3.4" pulley for a 2.8" .
Who has got the closest guess to my RWHP & Torque numbers?
I'll post up my numbers when I get back.
closest combined total

[RacerX]

445rwhp 452rwtq

[LANDY]

thats a big jump in pulley size. it will feel like a different car. enjoy
it all depends how far you and your tuner want to take it but i say you can get
460rwhp 448rwtq.

[Motorhead350]

469rwhp 440rwtq

[BODYMAN]

439rwhp/443rear tq this a very open guess brad as Iam not awre as to what all you have changed? were wer you before 415ish range? what all did you do to her

[Bradley G]

upgrades include;
GT40 fuel pump, ex-cal II, 2.8" pulley & belts, relocate IAT sensor, make the fuel pressure sensitive to boost, new Maf & open filter.
highest HP #'s 399 to date with CAI.

Oh, the car? 458 / 442

[Loco1234]

486hp - 465tq You will love the new pulley. What is your new target max boost #?

[SID210SA]

Combined: 924

[SC Cheesehead]

Over 9,000

What a blast!
I'll post up a fresh thread and let you guys in on the details.
everyone was too high!

C'mon, Bradley, we're all awaiting the good news.

Ok the tune is incredible, I did say I would post the numbers in this thread.
For a baseline the car made 311 HP/361 TQ on a 91 octane tune stock tune.
Then we went to work on the pulley swap.
That sucker was not easy to get off after 5 years and 70K+!
Then the intake upgrade to 90mm lightning maf and the open filter.
The first pull had us just shy of four bills on both counts; 395hp/398tq
Lonnie chased a lean spot on the curve, till we realized the air compressor supplying the dyno blew the breaker and skewed our last few runs on their Air/Fuel readings.
Once all the fuel trims were in order, Lonnie put a small spark add to the tune
the one degree advance from there put my final numbers at 418 rwhp/ 416 rwtq;
We were flatlining the Maf at 5K even after extending the mafs range.
Lonnie felt any more spark advance without control of the MAF counts would not be prudeint for a 103K Mile street bruiser!:bows:

The last dyno run which was five years ago had me at 349 hp/360 tq.


What I really like is the torque over 400# come on before 3000 RPM and stays flat as a table through 5100 till it drops off.
The other amazing thing that improved is the throttle response and transmission shifting it's like the trans alreadys knows what to do when you give input.

The hole shot is a joke , actually any rolling stomp I tried has the tires crying.
1-2 WOT is a tire fire as well.
On the highway it feels like a missle !
I love the way it sounds echoing off the other vehicles as I roll on past!
Big thanks to Lonnie Doll for his diligence and expertice you are a big caliber guy !

C'mon, Bradley, we're all awaiting the good news.

I thought the Trilogy would put out 425 conservatively and upto 460 or so with a lot of tinkering?
Seems a little low for Trilogy numbers...no???

[Bradley G]

Lonnie could have leaned on it till 500+ RWHP, but I have 103 thousand miles on stock internals, a pegged Maf after 5K and a very heavy foot!~

Congrats man! How much boost?

[Bradley G]

a crum over 15# you gotta try this car Bob!
Congrats man! How much boost?

[Lonnie@BOC]

It's making over 14.5 from 4200 - 5200 rpm with the pulley change. Just over 15 from 4900 - 5100 when the belt starts slipping and dropping him down to 13.2. A better belt tensioner is in order. The biggest concern was not going lean since the 90mm LMAF pegged a lot sooner than I thought it would. Hindsight I should have had him purchase a BA 2600 or I could have rescaled the LMAF and started over. I kept his timing really low until the fuel was where I wanted it. This is his only vehicle so it needs to last. Having that many miles on it already and it's been run hard all its life, not abused though the tune needed to be conservative. Once I was sure wouldn't go lean on him it was just a 3 hp shy of 400. Brad wanted something over 400 and the tease of just few away was too much. Adding a single degree put him to 418. That gives you an idea of what it could really make if I turned up the timing and had a better MAF even with the belt slippage.

Thanks to Jerry B for hooking Brad up with manifold adaptor plate with the relocated IAT sensor and then I corrected the boost reference for the FRPS also helped to keep his tune safe.

Going by his last dyno tune he's picked up over 60 rwhp / 50 rwtq with just the pulley change and a very conservative tune. The added power is right in the rpm range he needed it most.

Lonnie, I am really interested in this trans schedule after a long talk with Bradley. I am either keeping the car as is, or doing a pretty radical drivetrain replacement and going turbo if works goes strong thru the winter months. I will be in touch. Great work man.

something dosnt seem right. im no tuner but i have a 90 mm L maf and i make 435/432 with 14psi and 12* of timing and im ALMOST maxed on the maf with without a mafia. these numbers were fine with me so i didnt put a mafia on it. you have the potential to make 460hp easy

I’ve actually seen them make more than yours with that amount of boost and timing you are running. He has less timing than you by the way. It all depends on where the peak boost and timing are at in the rpm. There’s a lot of these out there that are making more power but like I said I deliberately kept the power down. This was not a dyno tune to see how much power it could make. I know it will make more than enough to put windows in his block. I’ve even dynoed one that put down 478 with a stock block but I also knew it wouldn’t last long no matter how safe the tune was so I had to back it down. I’ve also seen one that let go just over 360 rwhp with the a/f in the mid 10s besides several in the same hp range as yours with a safe tune. His would no doubt pass your numbers at 12 degrees.

As for the MAF, the 90 LMAF is good to about 425 - 450 in most cases. With his reaching the measured air flow limit that should give you an idea of what his power level could be if the timing were increased. I was able to rework the top end of the MAF’s range to keep him safe without a MaFia. I would assume that your tuner was at the last cell of the MTF during your tuning which leaves you with nothing to adjust the tune with also.

Thanks Bob, Brad said he was taking you for a ride before the weather changes.

i was not doubting you capabilities, as i stated, i dont know **** about tuning i was just stating facts i knew about my car. my car is very de tuned, i wanted it this way. i also know my car seems to be a bit weaker then most other mms from my N/a days comparing numbers with similar mods i was always on the low side. i dont understand you last sentence either.

No problem... I've run into a few that wouldn't make any decent power NA also, to the point it wouldn't break the tires loose. The MTF is the MAF table that is used to calibrate the MAF / a/f ratio while tuning. I'm assuming your tuner was at the limit or last cell in the table for it. If so or even in the last couple that gave him no room to really make any adjustments in the tune and so requires you to go with a different MAF, rescale or use a MaFia.
