well today was my tune and im very happy with my motor and these cams. the car is about 350 whp on 15psi almost 16psi. the psi falls down towards redline but keeps making power. i was too nervous to push to 19 or 20 psi cause of my cast pistons and stock rods. my rev. is 8800 btw. if i try 19 psi the car should show around 380whp about. all on e85 and 93 pump gave us 310hp on 10 psi. the dyno wasnt accurate today so i dont even have a graph for you guys. these cams like high rpms and i did degree them. intake retard to about 2 degrees and exhaust advance to about 2 degrees.
thanks for all the input guys. i would like to thank my brother for his help and xenocron for great service thanks guys.

Didnt want to post this in the GSC thread I see!!

Did you try running the cams at 0/0?
Id like to see the dyno graph even if its not accurate just so I can see the curve.

What's your complete setup?
And what were your previous cams

Kr4nG

iTrader: (1)

i dont have the graph maybe my tuner can post it he might have something.

previous setup was the same except ctr intake cam and gsr exhaust cam rev. was 8200. stock valvetrain. 6262 ball bearing precision turbo with the ramhorn and a/c.
car made 324.2 whp and around 240 tq on 12-13 psi and 93 octane.

today the car is gsc cams and supertech valvetrain (dr springs) rev to 8800 (can put to 9000 but i like 8800 lol) 1000cc id injectors with e85. and no more a/c cause i want better cooling flow into my engine bay. 2.5 inch elbow from turbo into a 3 inch right before the oil pan continuing 3 inch exhaust no cat. the compression is a little higher than an ls its about 155-160 psi when i did the compression test. on cast pistons and stock rods. all gsr head and block

we didnt try to 0 0 the cams the car was pretty responsive my settings but i can try advancing the intake cam 1 or 2 degrees to see if my mid range feels better. but for now the car feels very good.

videos?

that is a clean body car...good numbers!

rico892002

power seems a lil bit on the low side. What gsc cams are these? what compression is the motor? with the power u made you could have made this with gsr cams. very clean car tho

power seems low for the setup, my b16 with stock rods/ctr pistons and b16 cams on e85 made 399whp and 280trq on 15psi out of a precision 6031. Nice setup none the less! Compression test numbers seem a lil low if you are running stock gsr pistons.

blackeg

ehhh i hate to hate (lol) but that is definately low compression for a stock gsr block/piston. id go with leakdown test to get more info. though the power was a bit low, you did have some nice gains which is where the cams came into play.


what do you mean specifically with the dyno not being accurate that day?

Kr4nG

iTrader: (1)

sorry should of mentioned. the pistons are low compression pistons but not forged. not gsr pistons. and the tune was very very safe. i didnt want to make my tuner push it. we had bad history with this motor and didnt want to repeat it. the car is easy a 400 whp car but like i said i wanted to be safe.

the dyno is on its way out and its not reading anything close to what the car actually is. and hes not bullshiting me cause i can actually tell the difference.
gsc t1 camshafts

all i wanted to do is share my setup and what happened with it thats all. this motor has over 200k on it and the block was never removed from the engine bay. nothing has any machining done. it was just built by me and painted and bodywork all done by me. If i had a car trailer i would of just told my tuner to go all out but i needed to drive home and that was very important. some might say its a bit low but as long as im happy with it. next year i might change it up a bit who know.

thanks

hmm
those numbers are low
grant it i have i built my motor and i made more hp at the same psi levels you mentioned
cp 9.1
eagle rods
itr cams
ramhorn
garrett 57 trim 63 ar

345 @10lbs
382 @15lbs

im not hating at all, please understand that, i know those cams are well worth the money. but you can definitely get more if you redo that motor of yours

He said cast pistons and not gsr's. Nippon?

Kr4nG

iTrader: (1)

yes nippon.

i understand they might be low but im just approximating my power as well. i have no idea what the exact number is.

again this is a very safe tune the car can probably see 400 on about 20 psi. the psi also drops down a bit towards redline but still pushing power.

im just trying to share thats all. next year things will change im sure. im just gonna have fun with this for a bit.

blackeg

Ok, the way you originally presented it made me think it was a bone stock bottom end. Did u upgrade to arp rod studs as well?

I've always wondered about those nippon pistons as a low cost alternative for low to moderate power engines that would really be on the borderline of oem piston limits

WTF.... i'm no expert at all but i can tell you something is not right.
Either the dyno is not reading right and your making ALOT morepower than you think or something mechanically wrong.


Here's my setup:
stock gsr longblock + skunk 2 IM
mini-ram + 3" dp
GT3540S
Crome
FIC 1100cc injectors
E85
330whp @ 10psi
395whp@ 16psi
Reving to 8K & mild tune cause I told him I may drive it in the fall when they switch to E70 & didn't want to bother with retune.


Honestly i think you have some boost leak cause your boost shouldn't tapper & you should be making a lot more power especially with the GSC cams.

Hope you figure it out pal.
Charlie


If you made 320whp on 10psi on 6262 full ram on e85 or pump gas somethings not right.
There's no point of turning up the boost until you figure it out.

kbouchard1092

Why get such a large Turbo for a Block with OEM internals? do you plan on upgrading soon?

Especially if your only looking to make 400whp...you shoudlnt even have a 400whp goal on oem internal

Making the same if not more on my GSR cams...
But he said the power is a guesstamete lol he might be making less power on that 160 compression, basicly got tuned on a but dyno.

Hyper16-Johnny

The turbo is sucking hot air from the radiator that's why power level is low. Make a custom intake for that turbo and retune, guaranteed instant power!

GsrIntegra789

We will go to the track and the trap speeds will give us a better idea of the power it is actually making. Once Chris gets a new dyno, its worth a shot going back and doing some pulls with 0,0 cam settings. Also, I agree about sucking hot air straight from the radiator. Flipping the turbo may be a better idea now that the AC is out of the car.

Charlie Moua

iTrader: (3)

I'd say that may account for like 20-30whp but not much (for similar setups) more cause it's not like there are no fans or the hood is closed during dyno testing...

I'd me more focused on why the boost tappers off when he's reving to 8800rpms.

GsrIntegra789

Since we know for a fact there are no boost leaks. (tested it) I would say its either his MBC or the cam settings are not ideal at what he had set them to. Would it be possible hes blowing some boost out at higher RPMs?

DDTECH

Unless his cam timing is that much off, no, these cams aren't exactly super duper huge to be blowing boost by at 8800rpms..Then again i've seen weirder things..

what degree settings does the op have them set to now? Did he move them on the dyno to see how the powerband moved? If so, to where.. what are the v2v/p2v clearences when degreed in.

Muckman

iTrader: (2)

Everybody Ive talked to said they made best power with the cams at 0/0. These are designed to be a drop in cam. I also want to know why the OP is running intake at -2* and exhaust at +2*.

Kr4nG

iTrader: (1)

when degreeing thats what my settings came out to be. right in the middle of the duration my crank was showing me the correct number numerious times when i rotated the engine.

no arp rod bolts just arp headstuds here.

this build will have better pistons and rods in the future but right now its just almost a stockish build.

i need to put this car on a different dyno to get a chart because this car actually might be in between 350 and 400 it feels nice.

i think the boost might be droping because of the ebay manual boost controller it makes a loud sssssshhhh sound when in boost. and i placed it in my cabin so i know its the actual controller making the sound not my turbo haha.
