[QUOTE="Moaz, post: 16099791, member: 194040"] Hi all, most of you pointing to very important things, but as per the last test, there were no boost leaking at all, pulley and belt were in place and tied very well. So, we have a root cause right now, which is the low-compression (i've no idea about the original engine, as I bought the car with this engine), Now the compression is 9.5, which after hundreds of searches, we have them partitioned to two islands, 1- one of them saying having high-compression like the 11.x supercharged is very safe and medium-durability (engine-lifetime) as long as between 700-800 RWHP, and using race-fuel is a must (which making the car is only for the track not street use in daily-basis usage or even weekends events) 2- the other side saying that going with Supercharged engines, it's the best-practice to go with low-compression aka 9.5 and add high boost on it. by doing so, low-compression gives the benefits of, long durability (lifetime), no need for race fuel as pump/gas station is safe to be used up to having 700 RWHP on street usages (daily-basis) and if Meth kit is used, this would be very generous to the engine. The only drawback here that to get 800-900 RWHP, you need very high boost like +25 PSI. So, I've two questions here, 1- If I asked your opinion about each of above, what would you say? 2- The most important now is, I've the engine semi-new, only 10K miles on it, so, what do you recommend to do to get that higher HP like 850 to 900 RWHP ? Side notes, 1- I have no idea about the size of the pulley installed right now, and am out of the country so I can't get the size label on the pulley it self, but in any way, I will order the smallest pulley which is 3.40 along with 12-rib built. 2- I have no idea about the current impeller RPM, but D1SC max supported RPM is 62,000, so we will have a look on the tune and see how it sat, then we will get it to the max. 3- I have no idea about the overall tune, but as per the tip given by the previous owner, which was tuned on the maximum safe-levels (I would say conservative tune), so, I have some local tuners who are experts as well so they can have a look and advise how can we get more out of this.
