There's a guy in AZ who has one that he is planning to push to 8K+. Lots of mods, though.




I have a billet 3" stroke crank for sale if he wants it

it does, I'm one of only a small handful of people who still post there, facebook stripped all of the users away. Same for many of the forums that used to have a large following with hundreds of posts per day.

Totally agree with you!

I love how your engine is being compared to N*s and 3800SC's now instead of the swap that never made sense to me 3400...

Any tool that measures that same power source at the same rate of change of RPM and produces a different number is WRONG. There are LOT of ways a Mustang dyno can produce radically different results than a Dynojet.




Yep you are right Will but that test was Dynojet sponsored. But to get that out of the way I took my 2.8 to both dynos and look what happened.


Dynojet dyno


Mustang dyno

Exactly the same!

But like you said, I use dynos as a tool to measure my improvements not to brag.
I use the comparison with your N* as a reference of what an individual can achieve with any engine.
I know that if you make yours as radical as mine you'll be in almost at the 500WHP N/A because it has the hardware to achieve that.
Through your build I've admired the skills you have to make parts. For example, I don't have the machinery or the knowledge to
make a Quater Master clutch set fit in my engine (my dream) but I know that's beyond me, and you did it and I admire that.

So what I'm trying to say is that if you felt that I was putting you down in any way by comparing my engine to yours that was not the case.
And if you felt that way I owe you an apology, you are my best critic!
I'm looking forward to see your N* on the dragstrip and not brake more axles like me!

You know La Fiera I love the way you have added so much power to an 3.4 and you have proven it many times congratulations!

The points I want to bring is: Engine reliability, not sure how many km this 3.4 will endure,
Fuel consumption = Ouff ...

Of course, your goal is not to make it an everyday car.

I made a swap in my fiero 87 with a 3.5L Pontiac G6 2005 LX9 5 speed and I have another fiero 86 with a 3.8SC automatic, both with very few modifications.
The 2 engines run like clocks with very good performance and a good fuel consumption and a very good reliability.

We have 2 different thought.
And for finish your 3.4 since you converted it to the E85 I really don't like is rough idle.

Merry christmas everybody and La fiera continues to surprise us with some new modifications on the future 3.7 L



Its nice to see international fans Claude!
Fuel comsumption I don't care, its a Time Attack Racing car. More gas means more power!

Reliability, better than any stock 3.4 or any other stock GM engine at this power level because I improved things the factory missed because of budget.

The Idle roughness is not because of the E85, its because of the aggresiveness of the camshaft. Here where I live in the south they call that Lickin'!

Thanks for the support Claude!

I've seen one of your videos and your car looks and sounds radical!
Very well built engine.
Like to know what wheels and tyres you are using?
Regards, Rafe

So you are fasting for the holidays? Best of luck!

Just to clarify my point for the Idle roughness.

I said: And for finish your 3.4 since you converted it to the E85 I really don't like is rough Idle:
You replied: The Idle roughness is not because of the E85, its because of the aggresiveness of the camshaft. Here where I live in the south they call that Lickin '!

I watched the 2 videos again: https://youtu.be/qaDRamsYUtY
You are going to the dyno session and your Idle is really sweeter than on the other video: https://youtu.be/CUCOC4cxjo8

Did you change anything other than the coil pack and the E85 between the 2 videos.

In the future can you explain more your session of tuning please I'd appreciate lot's.
