Well guys looks like me and Terry had abit of a blonde moment yesterday. After all the confusion about the rev limiter being stuck at 5000rpm, i was thinking to myself today trying to work out why it would set itself so early for no reason on the dyno, because last night she would rev very strongly to 5500rpm with no dramas in 1st, 2nd and 3rd. Well what do you know i figured out that at 5000rpm in 4th gear we must have been coming close to the 180km/h speed limiter. So thats what was causing us all the trouble.
So late next week once Terry's dyno is well and truly up n running, we have organised to bring it in and increase the speed limiter carefully in 10km/h incriments untill we reach the peak of the power curve to find out exactly what its got in it, hopefully i'll see another 10-15hp.

awesome.. doesn't look that different specs to what I'm doing with my capri.. except I'm running Edelbrock RPM's, Edelbrk RPM intake, LINK Ecu and a C4 and 3.22 diff...
can you post cam specs?? I was hoping to get 300hp at the crank.. lol |

I am booked in with Terry for the day on Monday for a Tweecer tune.
My combo in ED is similar to yours except it is auto & has 2031 cam. How is your idle & how much work if any was needed to sort it because of cam. Dom also did my exhaust (twin 2 1/2 with crossover ) but drones like s**t, albeit an auto. What mufflers did he use & how would they go on an auto. Richie

Idle is absolutely beautiful mate, I heard from everywhere that the 2040(E303) has a pig of an idle, is a pain in the a*** to drive etc, but with the right tune and tuner and having everything else in the combo matched to the cam it has turned out excellent, i cant pick a fault with it. The idle is smooth with that slight lump (sound snice cold), and from bout 2800 it just pulls all the way untill redline. In the wet this morning it was very fun. Definately keeps ya awake lol. You cannot accelrate hard in 1st, 2nd or 3rd without flashing to redline with wheelspin. 1st is quite obvious thats its gonna spin the tyres hard, 2nd will accelerate with traction untill bout 3800 where it will just light the tyres up and flash straight to redline in a second and 3rd will accelerate hard with traction untill bout 4500 where it will start skipping trying to fight traction. As far as the exhaust goes, i supplied Dom the mufflers which are Hooker Aerochambers which i sourced through Dave @ A1. I have no drone at all with this system, cruising at 80-100km/h i cannot hear the exhaust at all, but as soon as you open up the throttle she just roars. The mufflers definately have a unique sound and have had nothing but good comments about the note. I feel the 2 1/4" twin system i went with is the best system to work with my engine combo, sure i could have made a few extra HP up top with a twin 2 1/2" but i wouldnt sacrifice the mid range torque.

Heads are Edelbrock RPM #60259 170cc intake runners/ 60cc chambers/ 2.02" intake valves & no EGR port. Using 1.7 Crane Gold Race RR.
CR is ~10.5:1 I have issues with closed/open loop at idle. Richie

Thats a big jump in rwkw considering peak power is produced at the same rpm as a stockie 220 kw 5l. What comp ratio are you running? What diff ratio do you have?
I personaly find it difficult to believe that a large cam as the one you have (and heads) can produce that kind of rwkw at those revs. If it was produced at 5600/5700 fair enough otherwise it needs to be a stroker. Large cam=poor vacuum and cylinder filling capacity= peak power at higher rpm. I think diff gears could have come into play? My car can chirp 1st into 2nd with 245/40/18's in the dry. Dudes with t3's can chirp 2nd into 3rd also in the dry. My old datsun 120y could spin it up in the wet. |

Hahaha im sure you can chirp your 18's from first to 2nd in the dry as of any other manual car. Dont worry this chirps 2nd to 3rd in the dry too, ya dont need a T3 to do that. What im saying is without hard changing gears or dropping the clutch, just accelerating in the above gears will break traction, im sure any car will spin the wheels in the wet and chirp into gear in the dry you tool. But accelerating in gear is a different story. Start ya own thread bout chirping through gears and 120Y's in the wet, dont bring ya crap in here. Why dont you start a thread bout ya own car?

Also what makes you think its such a large cam and head combo?
Only 220/220 and .529"/.529" lift with 1.7's, wouldnt really call that large.

I'm a tool heh. What fool put a single pattern cam on a ford v8???? Anyone and I mean anyone that has done their homework will tell you that on a ford v8 its a big no,no.
Seeing that you didn't build this engine or even see it in a million pieces reinforces my doubts. Have you seen how much smaller the exhaust ports/valve is in comparison to the inlet????? In other words a smaller dual pattern cam give you same hp and better manners. But hey what would I know. |

Ah okay, so Leon and Dave @ A1, who yes advised and assited me in cam choice to suit my chosen heads and goals etc, have no idea and havent done their homework on Ford v8's? I'll let Dave speak for himself here. If better manners is your only argument between cam profiles. What better manners could i possibly want? Idle is almost as smooth as std, brakes havent changed due to any vacuum issues, gear snatch down low is great and overall drivablilty is awesome. And of course your a tool, you prove it everytime you post, carrying on about chirping through gears and spinning wheels in the wet, when clearly i was talking about in gear stuff, where torque/power delivery/rate actually counts, no matter what torque/power your car has its gonna chirp through gears and spin in the wet. Amazing what a clutch pedal can do hey. And i'll say it again, Why dont you start a thread about your own car/engine build/modifications and post your info in there?

Everyone knows the specs of a 220kw windsor, they've been done to death so no point to harp on about it.
Oh and it's difficult to spin up a 400kg a*** end with sophisticated leaf spring suspension? Take it to the track and show us the 100 mph time slip; crunching dyno numbers is like asking how long is a piece of string. I reckon you'll run a 13.7 personally with slicks. 14 on street tyres. For a 302 thats a very respectable time I must add. |
