Well, i finally went and did a couple of pulls. i did 2 runs, first was 146.5hp and 131.6 torque, second was 141.2hp and 128.3 torque, i didnt give the car a chance to cool down. i have the following mods, pacesetter header, HS warm air intake setup, 2.25" exhaust, pullies, and all these on a Primera engine....does it seem good? i'd like to get some feedback.

thanks

PS, i will have some pics online later tonight, and video of the pulls one of these days coming up.

those are some kick ass numbers serban!look at other list members like naji who put down 147 hp with a cold air set up, hotshot header, and greedy exhaust, pullies. those sound really good. did you play with the timing at all?

Doug,

You need to dyno you car so we can know about the C1 cams on a 98. We know that the C3s suck on my car. I am very interested in yours.

Tell me how much your car weighs when you ran your 1/4 mile so I can deduce your hp with these cams.

Keep in mind that the primera engine comes with more aggressive cams and 10:1 compression ratio. That makes it stronger than a regular engine.

Keep in mind my 93 SE-R made 146.6HP with CAI, HS Gen3 and Greddy catback with stock colapsed cat
I was at the R&D dyno day there Naji, U remember
I have added pullies, JUN flywheel, ECU and few other small tricks to the head and intake manifold and a new cat !! my MPH went from 87MPH with the bad cat to awesome 97MPH...car ran like **** with a clogged cat, most of the exhaust was coming from the gasket before the cat hehe. I estimate somewhere in the high 150HP at the wheels range with a stock 93 motor. I give it exacly 158HP at the wheels.

I need to add the cat colapsed after the dyno about 5 months ago when I spun a rod bearing. I removed the primary to secondary to get the oil pan off to repleace the rod bearing. I didn't have a gasket to install so I got some muffler cement to seal the old gasket...needless to say some of the cement got into the cat... Its now sporting a Catco replacement cat that cost me 50 bux. Car passed emissions with flying colors.

Yea really good numbers. I remember Mike K, Rob C., And a few others commenting about the fact that a simple bolt on JDM engine puts down 140+ sometimes. And how a JDM engine with mods is like say 1000 bucks maybe. Not bad most say.

Next question is how did the graphs look? Like how flat is the torque, and where does it really kick in, that type of stuff. The area under the curves are really important also. But I wish I could put down numbers like that. Reason why I want a dirt cheap swap whore to work on.

I don't think Naji had a Greddy exhaust but did it with a custom or stock exhaust. I know he didn't wanna coffe can exhaust on his car. He did have cams in it thou, the S3s as I recall. I was there when he dynoed and he was accutally the 1st one to tell me what I got on the dyno with my car as I was reluctant to see my low 110HP to the wheels. But I was happy to see over 140HP ! Sounds pretty happy now snarling to 8K RPMs, gotta love that ECU. Rockers are also pretty happy. Its got this strange resonace at around 6900 to 8000RPM sounds VTEC-ish hehe.

ok, here are the pictures, the lines may be a little hard to see since they are so thin, but you get the idea.


this is the first pull


second pull

i was going to do the timing on the second pull, but i think it was still at 17 degrees. i have the UR pullies, and the marks are a little different, and i just decided to leave it alone, but car was on the whole time so it got all hot, and i didnt run as good.

well, what can i say, i am pleased with the times, stay posted, i will try to get the videos soon.

Why did you lose so much between the first and second dyno run? Usually dyno runs are within 1 hp of each other!!!

Yes Mike, I had the custom exhuast and the S3s. I wish I have kept my S3s and not traded them. Now I am kicking myself. I really feel like a jackass for getting those C3 cams. I should have kept the S3s, got and ECU for the S3s and that would have benn it.

But the Red Mist will rise again
I will hit the 165-170 hp mark with simple bolt-ons and cams. And I will keep some of the good mid range power that the S3s had.

the car had plenty of time to cool down before the first run, but after the first run, i left the car running since i wanted to mess with the timing, but decided not to do it, and just do the second run, so the car had no time to cool down.

I know Naji, I do need to get to the dyno. Check out my kill story from tonight. It was sweeeeet!. I am really curious how the c1's do too. When Rob Cadle and I spoke he told me the power curve was really flat and he put down just over 152-155 hp to the wheels with the C1's. I have a couple other things done too so hopefully in the 150's somewhere.By the way, I believe the cams in the primera motor is the same. The compression is good for a few ponies though. The car will overall respond better to mods with high compression. Anyway, those are some kick ass numbers.

Naji, use this opportunity to get the S4s instead if you do decide to get JWT's again

Hey Naji if I was you I would get C1 cams for your car since you have valvesprings and retainers in your car. The C1 cam is the best cam for the lowport motor. The problem with the low port motor is the size of the runners which is 1.5 ID, the runner length is about the same as the high port which is 1.75 ID but by making the ID smaller on the lowport you have made the runner that much longer. This speeds up the air in the intake which does not favor a big cam.

I remember when I e-mailed you in private, you recommended the C2s. I should have listened to you. But the power greed bug got the best of me


Do you still recommend the C2s for a high port like mine? If I get the C2s I do not have to reprogram the ECU. If I get the C1s I have to do that.

I know Doug is making good power with his C1 on his 98. But I would love to see a dyno chart from him. What do you estimate his peak power at?

Well if you want to discuss the cam issue with me call me at 305-282-3643. Sometimes I recomend things to people and they think I am not being honest or they think I am try to hold them back, if you ask me a question I will always give you information with alot of thought behind it.

what gear is the car supposed to be ran on the dyno? for a NA car, mine was done in third gear, and i was told by some that its not as accurate, and gave me higher than normal #s.

i would really like to know.

thanks
