That is correct. Aaron told me these blanks were incredibly hard to find, hence the rarity of the cams, but did mention they would be moving to a new blank.

I'm running the same cams Aaron is running in his personal car, and Mikey is running in his FP-Black 2.4LR.

I only lost 300 Rpm of spool but the car does have a pretty lazy feeling to it now so I don't blame ya lol

 

You were also going from 280 to 280 ;-)

 

Comp 280 is no 280, there actually smaller then a kelford 272 and pretty close to a hks280 from what I remember.

 

ya i remember you sharing this graph with me.. killer power man, and the curve looks good.

the higher the ethanol content the better the charge cooling effect you get.. so e98 will give more gains then say e85. ive said it before but im gonna mention you can still hit mbt on e70, but if you compare power to e85 you should see slight gains due to the cooling effect the additional ethanol content offers.

what compression is the engine?

e85 also helps make the engine more efficient. the cooling effect improves the ve allowing more air to be put into the cylinders without actually effecting the pressure of the cylinders.

the only downfall to e85 is it will slowly work its way past your rings and slowly dilute your oil over time allowing the engine to actually burn the oil off slowly. so do oil changes every 1k atleast and frequent check your oil levels.

 

This is 9.0 Compression as it will be run on 93 a lot of the time.

 

oh ok, same as my engine then. be careful on what you do with the cams, if you're the type of guy that wants low end kick if you do something that makes it laggy downlow you might regret it.

 

I've done A LOT of reading and comparing over the last few months. I have my mind made up. Shouldn't lose any spool (might actually gain 200-300rpm) and will gain huge power up top.

As far as the e85/e98 thing. I'm not running e98 to make more power than e85 (although it is a nice side effect). I am running e98 because it is readily available to me and provides a consistent mixture. I don't have to worry about testing ethanol content or running a pro efi with a flex sensor (not saying the pro efi might not happen in the future). Just that extra peace of mind not having to worry about contaminated e85 or getting anything from e60-e90 at the pump.

 

e70 to e98 etc, the less e content the richer u run, since the more e requires more fuel. so cant really get to dangerous in that department. although rbt and lbt can shift ignition points to mean something different then what the vehicle was once tuned for since burn rate is effected.

the contamination thing you mentiioned is a huge deal to me.. i only stick with amerigreen e85 stations otherwise its taking a chance. ive been getting the e85 from the same station now for 2 yrs and refuse to fill up anywhere else. call me overly cautious, but i feel its the only safe thing to do.

wish i had e98 at the pump.. lol.

btw what cams are you switching to the gsc s3's?

 

And i thought you were going to post pics of the rest of the car, Puleeeeze!

 

Mine.

Just out of curiosity, what makes you think that an S2 will gain spool over an HKS280? I went from HKS280 cams to a set of Kelford 272 cams and lost 200-300 RPM spool. I will be going to a set of S2 cams in the future in the hopes of regaining a little bit of the loss, but I wouldn't expect them to spool better than the HKS280 cams. IMO, if you're lucky the spool will be the same.

edit: actually I should've asked first - are these Evo 8 or 9 cams?

First off, its not a s2 its a completely different cam, second the hks 280s issue with this motor/turbo set up is that they literally don't let enough air into the motor. The hks 280 to s2 comaparo's have shown no increase in spool (not talking about the few hks 272 to s2 comparos). Aaron @ ER went from s2's to the new cam w/ the same result. In any event I'm not as worried about a few hundred rpms of spool as I am transient boost response.

To answer your other question, these are VIII cams. I didn't feel like adding another component that could possibly fail at these power levels (mivec).

 

awesome setup!!!!

 

There are a few shots in my build thread. I won't be posting more until I'm done with the interior as well as a few touch ups ;-)
