The supercharger being in direct contact with the cylinder heads and sitting directly over the valley of the engine reduces thermal efficiency and heat is always the enemy in positive displacement superchargers. With the Thermal reduction plates the blower will operate significantly colder, reducing heat soak and increasing consistency. The air entering the combustion chamber will average lower temps and be denser, allowing a HP gain and when tuning more ignition timing thus again more HP.\u003c\/p\u003e\u003cdiv class=\"figure\"\u003e\n\u003cimg decoding=\"async\" class=\"alignnone wp-image-12685 size-medium lazyloaded\" data-src=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp\" alt=\"\" width=\"768\" height=\"560\" data-srcset=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp 768w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1224x892.webp 1224w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1536x1119.webp 1536w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-416x303.webp 416w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-jpeg.webp 1798w\" data-sizes=\"(max-width: 768px) 100vw, 768px\" src=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp\" style=\"--smush-placeholder-width: 768px; --smush-placeholder-aspect-ratio: 768\/560;\" sizes=\"(max-width: 768px) 100vw, 768px\" srcset=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp 768w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1224x892.webp 1224w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1536x1119.webp 1536w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-416x303.webp 416w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-jpeg.webp 1798w\"\u003e\u003cnoscript\u003e\u003cimg decoding=\"async\" class=\"alignnone wp-image-12685 size-medium\" src=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp\" alt=\"\" width=\"768\" height=\"560\" srcset=\"https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-768x560.webp 768w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1224x892.webp 1224w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-1536x1119.webp 1536w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-416x303.webp 416w, https:\/\/fiinterchillers.com\/wp-content\/uploads\/2021\/07\/LS1-Blower-Spacers-2-jpeg.webp 1798w\" sizes=\"(max-width: 768px) 100vw, 768px\"\u003e\u003c\/noscript\u003e\n\u003c\/div\u003e\u003ch3\u003eWhat engines and Superchargers do the plates suit?\u003c\/h3\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe plates will have a very dramatic effect on downwards discharge style blowers as they suffer the most from heat soak, they also have a temperature reduction on upwards discharge blowers. We have noticed with the blower spacers combined with our interchiller that that entire blower absorbs the cold temperature not just the intercooler core, this results in faster recovery times after wide open throttle and lower intake temperatures. So both upwards and downwards discharge blowers benefit from the spacer plates.\u003c\/p\u003e\u003cp\u003eThe plates suit LS1,LS2 style cylinder heads the brand of supercharger will not matter, the plates are 10mm thick and will raise the blower up by 10mm so check to see if you have enough hood clearance before ordering, 10mm isn’t much so they should clear most cars. You may also require a slightly longer drive belt, in most cases your current belt tensioner will have enough room to allow the increased height otherwise a ½ size increase in belt length is adequate.\u003c\/p\u003e\u003cp\u003eWhen the plates are combined with one of our interchillers the intake temperatures are reduced even further as efficiency is improved even further.\u003c\/p\u003e\u003ch3\u003eDownwards Discharge Blowers versus Upwards\u003c\/h3\u003e\u003cp\u003eMany people often give a cult following to certain brands of superchargers, however not many people have taken the time to look into how the superchargers intercooler system works and what effect one blower will have over another type.\u003c\/p\u003e\u003cp\u003eWith downwards discharge style blowers we have seen very high intake temps even on low boost and even whilst cruising on the highway not under boost, so much so one person was getting temps as high as 60c (140f) on a 30c (86f) day whilst on the highway not even in boost. So amazed at how high his temp was he called another shop and asked if they had the same.\u003c\/p\u003e\u003cp\u003eThe answer was on a 30c (86f) day they also see intake temps as high as 60-80c (140-176f) simply just cruising around not under boost.\u003c\/p\u003e\u003cp\u003eThese very high intake air temps will cause poor fuel consumption, ignition timing and HP loss\/reduction, fuel vaporization and when you do enter boost EXTREMELY high intake air temps which can create a higher risk of engine knock which can result in engine failure if not tuned to remove very large amounts of ignition timing.\u003c\/p\u003e\u003cp\u003eWe have drawn up a couple of images to show you how this effect is taking place. This is your typical downwards discharger blower such as the Whipple, Walkinshaw, SLP, older style Magnuson and Harrop blowers.\u003c\/p\u003e\u003ch3\u003eAir flow path\u003c\/h3\u003e\u003cdiv class=\"figure\"\u003e\u003ca href=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates2.jpg\"\u003e\u003cimg decoding=\"async\" class=\"alignleft wp-image-446 size-large lazyload\" data-src=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates2-1024x831.jpg\" alt=\"plates2\" width=\"1024\" height=\"831\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/831;\"\u003e\u003cnoscript\u003e\u003cimg decoding=\"async\" class=\"alignleft wp-image-446 size-large\" src=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates2-1024x831.jpg\" alt=\"plates2\" width=\"1024\" height=\"831\"\u003e\u003c\/noscript\u003e\u003c\/a\u003e\u003c\/div\u003e\u003ch3\u003eSuperchargers compared\u003c\/h3\u003e\u003cdiv class=\"figure\"\u003e\u003ca href=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates1.jpg\"\u003e\u003cimg decoding=\"async\" class=\"alignleft wp-image-445 size-large lazyload\" data-src=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates1-1024x771.jpg\" width=\"1024\" height=\"771\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/771;\"\u003e\u003cnoscript\u003e\u003cimg decoding=\"async\" class=\"alignleft wp-image-445 size-large\" src=\"http:\/\/fiinterchillers.com\/wp-content\/uploads\/2016\/03\/plates1-1024x771.jpg\" width=\"1024\" height=\"771\"\u003e\u003c\/noscript\u003e\u003c\/a\u003e\u003c\/div\u003e","brand":"Fiinterchillers","offers":[{"title":"Default Title","offer_id":45581913391263,"sku":null,"price":351.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0424\/7571\/6767\/files\/LS1-Blower-Spacers-2-768x560.webp?v=1718213687","url":"https:\/\/streetdrivenperformance.com\/products\/blower-spacer-plates-ls1-ls2","provider":"Street Driven Performance","version":"1.0","type":"link"}
