Blue is the baseline run, Red is the final SCT tune run. The tune netted a gain of 20 hp & 20 ft-lbs and considerable improvements where idle quality and low rpm drivability are concerned.

Baseline - 248.81 hp / 285.75 ft-lbs
SCT Tune - 268.97 hp / 305.41 ft-lbs

BLOCK - Stock 302
HEADS - Trick Flow Twisted Wedge
INTAKE - Trick Flow Street upper and lower w/1" spacer
CAM - FRPP B303
ROCKERS - Trick Flow 1.6 Rollers
IGNITION - MSD 6a | MSD Blaster Coil
AIR INDUCTION - 90mm MAF | AFM 4" Powerpipe | BBK 75mm TB
FUEL - 24 lb Injectors | 255 lph Pump | Kirban AFPR
EEC - AFM Loadio | SCT Chip (Bamachips tuned)
EXHAUST - FRPP Shorties | Prochamber | Mac Catback
REAR-END - FRPP 3.73's

Needless to say, Tracie was a little disappointed with the numbers, but at least we know what we're working with now.

:nice:

You mean she knows what she is working with. :chip:

[qkjuicedpony]

i had the exact same combo with no chip.although i had 1.7 rockers.that tune seems a little off.my car made 310rwhp and 330rwtq.

[94five0]

is that size t/b not massive overkill? same with the maf? reason i'm askin is most of the 300 bhp combos i 've seen are a lot less radical than what you've got.... like brian said..

at max, a 70 mm tb an just slightly larger maf?.. i had pretty much the same numbers with a set of stock e7's, stock injectors, stock headers, and a typhoon intake w/o a spacer. in addition to the regular bolt-ons: exhaust, fpr, pullies, and timing bumped..

that's a whole lot of hardwear for a 20/20 gain..

[1sicklx]

:nono: the 20/20 gain was from the chip alone .... the base line was before the tune.

[qkjuicedpony]

yeah the 75mm is a little big for your combo.i use a 70 and a 76mm maf on most smaller n/a combos

[QWKSNKE]

This guy had some similar results.

I guess the tfs kit does not make the power that it seems like it would :shrug:

The tune is definitely a significant gain compared to what it was without. Whole curve is way better :nice:

[QWKSNKE]

Just my 2 cents..

IF the valve covers allow it, remove the spacer. Its hurting the upper rpm power. I am in the same boat but I had to use a spacer to get my intake to clear the valve covers

[qkjuicedpony]

it isnt the tfs kit...i just witnessed one make 330rwhp in a fox coupe.

[qkjuicedpony]

how much timing is in it?

[QWKSNKE]

how much timing is in it?

I was wondering that as well. Did you notice the curve on Crzpny's at 5400 or so. Shouldn't it have kept going up or at least stayed flat and then fall at 6k rpm. I figure the tfs intake would flow better than my cobra in the upper rpm

[1sicklx]

It is the TFS kit minus the cam as the car already had a Bcam installed and we didn't swap them ... the spacer was used due to valve cover clearance.

Timing prior the tuning was set at 14 deg. I don't know what the timing/fuel pressure was at after Doug tuned it. :shrug:

[qkjuicedpony]

get rid of the 1.6's and put 1.7 rockers on it.and add a little timing and some fuel

Fuel pressure was set at 32lbs and if I am not mistaken the timing was set at 15 deg.

I am curious however about if the "B" cam is affecting overall performance potential. I used the same h/c/i using the trick flow cam in my '89 GT and it dyoned at 249hp with an automatic tranny.

[QWKSNKE]

I doubt the b cam is hurting it. I made 295rwhp with a b cam and 1.7 rockers.

EEC tuning should have been done with fuel press at 39 psi (vacuum off) and base timing set at 10 degrees.
What qkjuiced and are referring to, in regards to timing, is how much timing is in the car at WOT. Should be in neighborhood of 35-40 degrees depending on what the car combo likes.
For example, in my current combo my car did best at 34 degrees timing at WOT.

[qkjuicedpony]

i do know that the 94-95 processors can act a little crazy but i had the same combo in the same car without a chip.the only adjustments made were with timing and fuel and it made over 300.


how many miles are on the motor and does it use any oil,also are the rockers stud mount or pedestal mount?

The numbers I quoted for fuel pressure and timing were not WOT - those are where he set them at idle.

Car has approx 150k miles on it. Not sure exact number as my odometer quit at 147k. No oil used.

[qkjuicedpony]

the car is a 5 speed right?

[Crzypny]

:yup:

.


yeah I know. The 39 and 10 I referred to is the preferred settings at idle when EEC tuning

[qkjuicedpony]

how does the car run?does it feel strong?

still waiting to hear if it has stud mount or pedestal mount rockers

[QWKSNKE]

stud mount

[qkjuicedpony]

wonder if the valves are adjusted too loose??

They were not noisy when I drove it after installing 3.73's a few months ago.

And a fine job I might add! :nice:


I can definitely tell a difference in the way it feels.

Clutch is original, never been replaced, and Lee you know the vibration in the drive shaft I have .... just wondering how much of an issue these could be to loosing power to the wheels. :shrug:

[qkjuicedpony]

if the clutch is old and is slipping then it will show a power loss.

[QWKSNKE]

driveshaft won't cause a power loss it will just suck when you carry it up in the rpms.

I agree with qkjuiced. The clutch could be causing a problem since it is the OEM one. It may be slipping just enough to cause a power loss without noticing it.

[Crzypny]

driveshaft won't cause a power loss it will just suck when you carry it up in the rpms.

Ok, I was curious about that since it's not a smooth transfer of power from the tranny to the rear end.

3/4 of a turn past 0 lash.

After Doug added the chip the car runs great, good throttle response, good idle ... feels strong compared to before it was tuned :P

[coupe]

1.7's would be the easiest. But the TFS cam will run circles around the B303.

The car went 103mph in the 1/4. It has to have more in it than 260. :shrug:

It depends on the weather. If it's 260 with SAE correction, it could be actually putting down 280+ if it's cold outside. I have trapped 105 with only 280rwhp (SAE).

Base line run was made with the following mods on a 5spd foxbody:

Exhaust: FRPP Shorties | High-Flow Catted H-pipe
Air Induction: 75mm Pro-M MAF | Mac CAI

220 HP | 277 TQ
___________________

And here's the TFS Street Kit with the following mods:

Heads: Twisted Wedge
Cam: TFS Stage I
Intake: TFS Street
Rockers: 1.6 TFS Rollers
TB: 70mm Accufab Throttle Body
MAF: P-MAS 80mm MAF
CAI: AFM 4" Powerpipe
Exhaust: FRPP Shorties | Catted H-pipe

292 HP | 316 TQ

In this example the foxbody netted 69 peak hp from the TFS kit with additional changes.

94 GT baseline with the following mods:

B303 Cam
MDS Coil
FMS Shorty Headers
O/R H-pipe
Flowmaster 1 chambers

213 HP | 277 TQ

TFS kit minus cam with following mods

Heads: Twisted Wedge
Cam: B303 Cam
Intake: TFS Street
Rockers: 1.6 TFS Rollers
TB: 75mm
MAF: 90mm
CAI: AFM 4" Powerpipe
Ignition: MSD 6A | MSD Coil
Exhaust: FRPP Shorties | Prochamber | Mac Catback
EEC: SCT Chip
Gears: 3.73

268 HP | 305 TQ

That's a net gain of 55 peak HP without the benefit of a cam upgrade.

When you put it in perspective like that...sounds about right. I think a cam change is next on the list. Because it's about the same cost as a set of good rockers, which you already have on there.

rockers would be a whole lot easier to change vs a cam swap. Besides, while the 'b' cam is a old design it is still a good cam. I proved that with my first combo on the cobra
