How long does it take to fix a blown engine?
On a typical engine, the shop time quoted will be 10 to 12 hours. On an easy engine with a skilled mechanic, you may get quoted as little as 8 hours, while bigger jobs may require as many as 15 hours.
How many degrees of timing does a blown alcohol engine need?
With a very powerful 44 primary ampere magneto, only 22 degrees of timing is common. Nitro fuels run a lot more fuel volume and, as a result, need more timing. Example: For a blown alcohol engine on low percentages of nitro at a low level of enrichment, 40 degrees of timing was typical.
How much does it cost to replace a short block engine?
For a short block, meanwhile, expect to spend anywhere from $500 to $1,000. Aside from the cost of the actual engine, you also have to factor in the cost of the labor. In most cases, the hourly rate of local mechanics will be anywhere from $50 to $100.
What should I know before an engine swap?
Before an engine swap or replacement, these are some of the most important factors that should be given attention: Wiring: You need to understand the complex science behind how wires work. From wire gauge to amperage, you need to make sure that they are suitable for the new engine that will be used as a replacement.
Which is the best ignition timing for a blown gasoline engine?
Example: For blown gasoline at around 2 atmospheres, 28 degrees of ignition timing is common for best power. For the same blown engine on alcohol at a richer mixture, 32 degrees of timing is common. Example: One methanol combustion engineering test measured a 22% reduction in methanol flame speed for a 19% increase in fuel enrichment.
What was the speed at which my car blew up?
The failure on the car happened at 3,400rpm, about 75km/h under approx. 7psi boost, driving sedately from traffic lights to 80km/h.
What should I do if my mechanic blew up my engine?
