Any more reviews for this product wih the tune? Apart from improved driveability I wonder just how much faster the car becomes from 0 to 60. I am guessing aomething like .1 or .2 seconds faster? I am saything that because the power comes sooner (10 hp) and your reAlly not losing the late rpm power with the tune so their is simply more power.

I did some dyno testing on E85 yesterday and the results were as expected. Still picked up power in the 5500-6500rpm. But lost a fair it of power above that. Unfortuantely, it's the 6500 and up area of the power curve that usually performs so well on E85. And I was not able to get it back through custom tuning. I didn't exhaust all tuning possibilities but it doesn't look likely. So for those who run exclusively on E85 (and love the top end it provides), the Power Blocks may or may not be what you are looking for. I'll post dyno numbers after I spend more time on the dyno and exhaust all tuning possibilities

Cheers,
Shiv

Will be any benefit with Vortech + Block?

I don't think so. From my experience, power blocks and boost don't mix. Power losses everywhere. I think they are pretty specifically optimized for NA gasoline applications. Which is what 99% of people run. In that environment, they work very well.

thanks for the update

Well I just made my switch over to the OFT. Received it today infact. Thanks @shiv@vishnu. So far with the limited driving that I was able to do, the Stage 2 EL tune for the BPB works pretty good. Feels like the topend was restored. I also no longer feel the dip in midrange when running through the gears. It feels like it just pulls from wherever the tac lands. 1st gear is much nicer as well. Hopefully I'll get more time with it over the next few days, but so far I'm loving it. Thanks!

Thanks Shiv

Personally, would you prefer e85 or 93 + powerblocks ?

Since I am on e85 and lost a bit up top using the blocks i started looking at parts that help up top on the powerband. Muffler deletes caught my eye and from all the dynos i noticed that they really shine from 7000-7400 giving an 6-10hp gain which is pretty much what is lost. So im debating on getting a muffler delete to see if it helps. thoughts?

I was running a muffler delete with e85 for a while. I recently put back on the borla axle back I got with the car and I'm not sure if it's in my head but I definitely feel a little less pick-up up top.

bleh....well this confirms that my money is better left unspent for this "upgrade".

Boofneenee · 05-09-2014, 08:41 PM

is this worth it if you stay NA? according to the dyno their is a nice bump in tq and the power continues to redline with tune.

I say yes. Lengthened intake runners are(I believe) mainly beneficial to NA engines. They helped my car out for sure...don't plan on going FI.
