Thanks for the compliment.
I am looking for ways to upgrade it further. Is it possible to turbo charge it or NOS it?
One tuner told me, with high compression, I can go on light boost (about 0.5 bar). And there is no need to worry about turbo lag due to the high compression. But then he warned me that I might have to pump octane 98 petrol forever and even have to add octane booster.
I read from the manual of ZEX 82021 NOS kit (55 to 75 shots) that for every 50 shots, 1.5 to 2 degree of retard timing is required. But I understand that my current timing (as programmed in UNICHIP) are mainly modified to be advanced from 2-8 degree throughout the rpm range for the increase in power. Will that be a problem? I gained all the extra horses from the advances. Now if I were to retard, I will lose back those power and have newly gain from the NOS power. A bit contradicting. So need some expert advice now.
2-8 degrees if timing will give you MAYBE 3-4 hp. Nitrous will give a **** ton more than that, even on the smallest shot. It is suggested that you retard the timing but with a 35-50 shot, it isnt really necessary. I run a 75 shot on my other car with no timing changes.
That whole, no lag because of high compression, is crap. It is all about flow. If your exhaust ports flow well, you will have less lag. And on such high compression, I would boost it. It is just asking for problems.
In the daewoo community I see allot more warnings about detonation with turbos than other communities. I don't know if our engines are just more prone to detonation or if it's something that just got stuck in the communities heads. Anyways, that being said I know allot of people that raise compression on there cars (hondas, nissans, ect) AND add turbo. One friend is running 14:1 compression with 20-30psi but he is also on race fuel (probably 112 octane) and another friend is running 13:1 or 13.x:1 compression with 7psi on 92 or 93 octane. The last friend just finished his build and says he plans on turning the boost up once the kinks are worked through.
I would go with nitrous over a turbo with your build…. But a 1.8-2.2 over either of them. Nitrous will be less risky on your engine and you won’t have to run higher octane either.
Am running out of idea and direction.
Having a problem of importing NOS due to the strict custom. NOS is illegal item. Highly dangerously flammable goods.
Thinking of Rotrex now. But wonder whether to use C15-60, C30-64 or C30-74 base on 133mm crank pulley diameter.
If using 70mm diameter pulley on C15-60, will be running the rotrex at 145K rpm base on the 6400rpm rev cut. The limit is 150k. But wonder whats the boost at that rpm.
If using C30-74 and 70mm diameter pulley, will be running the rotrex at 119krpm, near the 120k rpm limit at 6400rpm rev cut. But also duno whats the boost at that rpm.
Nitrous is not flammable.Originally Posted by xiaogary
yes huh didnt you see the fast and the furiousNitrous is not flammable.
Or rather compressed gas container not allowed.
Indeed I never watch Fast & Furious before. I only watch Fast & Furious 2. I missed the first one and didnt bother to buy a DVD/VCD to watch.
Rotrex C30-74.
