F1A stroker stock heads and cam +E85 build

[05yellowgt]

No problem. I did have to do some nice grinding on the front Calipers and in order to get them to fit. I still haven't done the neccessary grinding on the rear wheels to make them fit. What is currently on the car is a set of Prostar XP 15x9 5.5BS wheels. I have a set of 15x8 5.5BS Greg Welds but they aren't anywhere close to clearing the calipers. Once tuning is done I am going to take the grinder to the rear calipers and see if I can make them work. I am in serious need of a rear wheel that properly fits under the wheel well so I can run a 28" tall tire to try and get this beast to hook.

Awsome setup very impresive getting those numbers with the stock heads and cams. I'm running a very similar setup and just warning you don't know if that clutch will hold much more. My spec stage3+ just let go on the dyno on saterday at 734rwhp. I'd say their good to about 680rwhp

Here's to hoping mine holds. What is your combo and what clutch are you going to go with?

My setup is a forged 281 shortblock with livernois stage 3 heads custom comp cams f1a procharger. It has made 734rwhp on 19lb of boost with the stock intake. installed c&l intake but was unable to get a full run on the dyno due to clutch. Going the automatic route and getting a built th400 so I can turn up the boost.

 

[05yellowgt]

How much were you picking up with the intake before the clutch let go?

The dyno graph showed torque up about half way through the run power was up also but once on top end it smoked the clutch. As soon as I get the new numbers I will post. John Lund (tuner for evolution) said it would of made another 50rwhp easily.

I'm very interested to see how it affects your fuel pump duty cycle and MAF counts. I'm at about 900 AD counts on the MAF right now and about 87% duty cycle on my fuel pumps. I want the C&L manifold for the purpose of evening up the distribution of air to each intake runner and make it safer to run the boost I am. You can tell a difference between the higher flowing and lower flowing ports right now when you pull the plugs on my car. Did you change throttle bodies when you put the C&L on?

As far as throttle bodies go I had a mondo blade ready to go on but decided not to put it on for intake comparisons only. But once tranny is all sorted out will be putting it on. Then I'll thow 26# of boost at it and see if I can get 900rwhp out of her. After talking to fred at evolution may be swapping the the mondo blade for ford racing new throttle body.

 

[05yellowgt]

Yeah the FRPP TB is the one I will upgrade to if I ever decide to upgrade.

At 6800 it hit 23.5 psi. I will be more than happy to share pics, once I get the car cleaned up. She is a dusty dirty mess right now!

Was that on the 4.1 pulley or 4.3 ?
Nevermid . I saw it was a 4.25. I guess that is correct since I saw 22 with a 4.3 at 6200 and 24 psi with a 4.1 at 6200. I guess this why everyone says to run race fuel with the F1-a . Cant wait to see what my 3.9 and a 50 shot makes!

 

[05yellowgt]

It's actually a 4.3 so taking into account cam, head, and compression differences our boost numbers are just about the same.

Well great news and some not so great news from tonight. Eric worked his magic and the car made 650/605 but the clutch doesn't like it a bit above about 6000rpm. I would think that the Stage 3+ in the car would be able to hold but it shows on the power output and if you graph gear ratio on the dyno graph. I don't know if I can get a replacement tomorrow or not but I am going to try so we can finish tweaking the tune and see if it will make 700.

Fuel pump is at about 88% or so with the base pressure at 50psi. Timing is right near 20 degrees so we have a few more to add in as there is not a hint of detonation.

That is awesome man!!! Keep us posted on the dyno time....Good luck!! It would be awesome to make 700...

Very nice ! So did you get the cluch in ?

 

[ZmanM3]

time for the Spec 4 or maybe a twin disk.

Nope still waiting on the clutch before we can get the final numbers.
