EDIT: dyno session 1 is posted.

Would it be safe to use Type A's on the stock B16 Valve train? I know that blox says that you can use them on stock valve train but I do beat on my motor quite a bit at autocross events etc. I would be keeping the stock revlimit I would suspect but I will be taking it to whitfield for proper tuning so i guess i'll know then. I also dont want to get valve springs that are too strong and wear down the cams so if I do upgrade the valve springs ITR would be good? I'll be using a thinner headgasket and getting the head resurfaced so that would up my compression a little.

What kind of power are people making from this cam Im not expecting any huge numbers I just want a little more power. My current mods are simple bolt on, 68mm TB, Blox IM, 4-1 header maybe upgrading to Whitfield tri-y, full catless exhaust.

Blox A are a good cam. Better than Type R, but if you stay with the B16a valvetrain then stay with the stock rev limit.

 

Dose any one have any other insight? How far past the stock 8200 rpm rev limit do these cams make power? Would it be worth upgrading the valve springs so i can have a higher rev limit or do the cams pretty much die at 8200 rpm's

 

Bump for some imput.

They actually perform a lot like ITR cams and stop making power around 8400 rpm.

 

They are slightly more aggresive then CTR cams but I still would upgrade the valvetrain.

CTR cams = 00-01 ITR cams

Agreed, ITR valvesprings at minimum

Im gonna be dynoing the car tomorrow to see what hp i have currently with just bold ons before cams and see how much HP and TQ is gained after the cams and head resurfacing. I still currently have the stock muffler on the 2.5 pipping I wont be upgrading that until I take in for tunning in a couple weeks. After tunning I ill see if the cams are still making considerable power at the stock rev limitm and if more power is to be had past stock rev limit I'll be upgrading to ITR valve springs.

I'll try and keep this updated as I go along.

Actually the blox only have .2mm more lift then CTR cams. ITR cams are 11.5mm and the blox are 11.7 if im not mistaken and 1mm diffrence on the exahust cam. The duration diffrence is about 3 or 4 degrees on both intake and exahust. But that is slightly more agressive as you guys stated.

Got back from the dyno, well take a look at the chart we only did two pulls and the car had been sitting for about 30min. The HP seems ok but the tq seems a little low, this was on a dyno jet. This was with the stock muffler still on the car and ebay ram air intake with the ebay filter and a correction on my TB, its 63mm not 68mm. Those parts other then the TB will be changed when the cams go in this weekend. I'll be putting in the ITR cold air intake and taking off the stock muffler for an es oval and adding a fuel pressure regulator. I'll be putting it back on the dyno after I get the cams on and setting the cam timing. I'll have to wait a week or so to save my pennies to take it to whitfield and have it tunned with chrome.

Free dyno time FTW!!

 

NOT BAD

 

This is a B16A? If it is, thats pretty good. Might wanna try out the Skunk2 Pro1s for more mid range.

 

looks like my old plot.

 

Yes, this is a second gen B16A, I have the Blox A's already so im just gonna put those in. Im kepping my stock valvetrain so thats why im going with a more conservative cam.

Keep in mind this is with my stock muffler on the 2.5 pipping, it's my old CX muffler so that thing is the size of a Mc Donalds straw. and my crappy intake. I was gonna try a few diffrent intakes that I borrowed but we ended up running a little short on time so we didn't have time to play with anything.

Ive decided to mill my head about .010" and use a 2ply head gasket witch should yeild about 11:1 compression so will se how much I can get out of the tq less b16. I'll keep the thread updated with dyno charts as i go along and maybe pics on the build.

Edit: if you look at the chart right around 7k the power starts to fall off a little when it was incresing i belive my restrictive stock muffler is to blame there.

 

bump for some decent info

 

so this dyno is with stock cams or with the type a?

 

I interpret it as stock.

If you pull the head to mill it and install a 2 layer gasket you might as well get some headwork done. Portflow is in So Cal as well, but if youre not looking to spend that much, PM me. I could take care of the porting and the milling for you, and that head will come alive.

The chart is with the stock cams on my pretty much stock SIR2 B16A, mods are listed.

I actually just installed the cams and JG gears earlier today, no mill or thinner gasket I was more impatient then anything. I've been toying with the timing in the garage and taking it out and driving im at In:+3de. Ex:-2de. but im hitting the dyno tomorrow morning I still have my stock muffler but I did install the AEM ITR cold air so will see what numbers I get tomorrow.

I would definitely be interested in you services though im looking to get about 11:1 compression witch would be milling .01" and using the 2 layer gasket I think I should be good with that, these are just A's after all, for now anyways I still would be interested in your help though, were are you located?

 

So Cal same as you. Why dont we take this to PM's and keep the thread on tech.

 

Ok, so I just got off the rollers, I ended up putting down 159.2 whp and 105.3 ft/lb of tq. The best peak hp was reached at 0,0 witch was about 159.8 but put down 104.1 ft/lb tq, I then palyed with the cam gear a little bit and end up with +2in,+2ex i picked up about 3-4 whp through the whole powerband but ended up with slightly less peak power.

This was untuned im still using the stock P30 So I still have the dip in the power band, I'll be taking it in for tunning at whitfield later this week or this weekend hopefully. I sitll have stock compression as well I never milled the head how I had planned. So I may do that first then tune, havent decided yet dont really know how much a diffrence 10.4 compression to somewhere in the low 11 compression will give. It might not be worth the work.

The set up:
Blox IM
Blox Type A cams
AEM ITR 3" CAI
62mm TB
Fake mugen header 2.5 with 2.5 collecter completly dented to **** on the two lower runners I put some pics up later maybe
2 1/4 piping into an es muffler of the same size

 

this was dynoed at whitfield? wow 17whp from just cams and exhaust?

 

cool beans

 

thats cool i was thinking about getting the blox type a's or either skunk 2 stage 1's

This was not at whitfield. The mods done are listed in my last post. This was on a dyno jet at the local city college, I get free dyno time there.

I would post the dyno charts but they are saved on the school computer that we have to use with the dyno. I didn't have a chance to email them to myself this time.

 

I just went to take some pics of my header and I noticed its cracked now. I know for a fact that it was not dented during the first dyno or at the muffler shop this past thursday but I dont know what kind of difference that would make. Its a slight crack. You can also see how badly dented it is, shitty ground clearance plus ricer height FTL!! I think it happend when I was going over some huge pot holes near a railroad track this past weekend.

To clarify the cam shafts were added and I switched from a short air intake to the ITR CAI.

 

any updates
