Remote mount water pump sounds way COOLER!!!! Is it the coolant pump/poor passage design causing these problems? Can you disclose any pics or diagrams?

Re: 11:1 CR Race/Street Engine build
I noticed that those who have tracked the automatic SVX do not seem to have had the overheating problems that us manual transmission folks have had. Harry (NewSVX) and Paisan have both tracked their cars without incident. Almost everyone who has tracked a manual car has at least had blowback into the overflow tank. I think this is related to the 6400rpm redline mandated by the automatic shift points versus the 7200 to 7500 rpm that manual drivers use.
Even Jack Laverty (Eg33 RS showcased here by RallyBob) has had a lot of overheating problems. If overheating is related to high revs, I want to get good torque between 5500 and 6500 so I can use 7000 to 7200 as a shift point. As for the cost, by the time it is all done, pistons, long block build, injectors, Hydra Nemesis, equal length headers, dual exhaust, it is probably going to be pushing $12k.

Re: 11:1 CR Race/Street Engine build
I read somewhere that the stock water pump of the SVX is extremely efficient, sometimes better than the aux electric pumps. Will the stock pump remain along with the electric pump or are you planning to delete the stock one?

Re: 11:1 CR Race/Street Engine build
Works for me. Looks like a killer build, can't wait to see what it will do!
Also, the parts vulture in me wants to know if you have two left over ACL bearings you want to get rid of. |

Re: 11:1 CR Race/Street Engine build
Sounds like a intresting build
Are you keeping it 3.3 or are you going to bore the block out a lil bit?

Re: 11:1 CR Race/Street Engine build
I am hoping to have the long block completed by the end of the month. Basically my hold up is getting the cams back from Web to measure needed shims and order them. Once that is done I will do the R&R of the engine and begin working in the water pump & headers.

Re: 11:1 CR Race/Street Engine build
Guys I think the cooling could be a big problem for our engine. We have a guy over here who has a racing buggy (think you guys call them sand rails) and it has a SVX engine. He can't keep it cool even though his radiator is about 2 times bigger then our PBR.
He just brought a multi flow radiator. Should hear by the weekend if it fixed the problem. It seems that we need to keep the coolet in the radiator for a longer time to get rid of more heat. I am not going to race my car till I fix the heating issue. Tony

Re: 11:1 CR Race/Street Engine build
I miss it on the track. The new roadster is too much like work. Very twitchy, very tail happy. Scary fast, but scary. Also, I loved being king of the hill when it rained, rather than the soaked guy in the little orange car sliding all over the place.
Have fond memories of good turns, especially after I got a handle on how to drive it. Looking forward to more of the same. Will need about 1000 miles to break it in, so it might be next season before I'm back out on the track.

Re: 11:1 CR Race/Street Engine build
As I have tried to explain before many times and so have others, the overheating is not due to an insufficient radiator. When the needle is in the red, the coolant comming out of the radiator is still at ideal temp. It is a restriction/stagnation in the engine's cooling system. That is why I will be keeping the stock flow path and merely adding new ports to the cylinder heads for aux cold water inputs to keep the water from boiling and causing the spikes in water temp.
